Answer 1

Natural vegetative propagation uses bulbils, aerial shoots, roots, underground stems, and subaerial stems. Utilizing unique vegetative components, artificial vegetative propagation is accomplished.

What is vegetative propagation, and how does it work?

The production and growth of a new plant through asexual means or from a plant fragment is known as vegetative propagation. There is no gamete production or fertilization throughout the process of propagation.

What are some instances of vegetative tuber propagation?

In this procedure, tubers—modified roots—grow into new plants. In some plant species, adventitious buds even grow on the roots. If the correct circumstances are present, these buds develop into new plants or sprouts. Sweet potato and dahlia are two examples.

Part 1 ( 0.5 point)
See Periodic Table See Hint
Which balloon, A or B, most accurately illustrates the effusion of a gas from the central balloon?
Calculate the relative rate of effusion for the orange to blue spheres. The root-mean-square speed for the orange spheres is 495.0m/s. The root-meah-5quare speed for the blue spheres is 380.0m/ s.

Answers

According to the claim, Balloon A, which has more blue and less orange, exhibits accurate effusion at a relative effusion rate of 1.303. (orange is 1.303 times more effused than blue).Relative rate of effusion for the orange to blue spheres = 1.531.

What is effusion ?

The process of effusion is when a gas escapes from a container through a hole that is significantly smaller in diameter than the molecules' mean free path.

Gas molecules flow through a small opening in one container and into another by effusion. Graham's law allows rates of effusion to be compared at the same temperature. Diffusion is the random molecular motion-based movement of gas molecules through one or more other types of gas.

Rate of effusion of Orange / Rate of effusion of blue

= [Mblue / Morange]^1/2

Vrms = sqrt [(3RT/M)]

Vorange / Vblue = [ Mblue / Morange]^1/2

Rate of effusion of Orange / Rate of effusion of blue

= 565/ 369

= 1.531

Thus,  Balloon A, which has more blue and less orange, exhibits accurate effusion at a relative effusion rate of 1.303.

What is the name of the ionic compound formed from lithium and bromine?

Why is the answer lithium bromide? What is the indicator that this is the correct name, rather than lithium bromate? Is this because a compound would need to contain 3 different atoms and oxygen to have the name lithium bromate? Is that why NaNO3 is Sodium Nitrate?

Answers

Answer:

The answer is lithium bromide because it is the combination of a metal (lithium) and a nonmetal (bromine). The indicator that this is the correct name, rather than lithium bromate, is that the compound is composed of only two elements and does not contain oxygen. Yes, this is why NaNO3 is Sodium Nitrate; it is composed of three different elements (sodium, nitrogen, and oxygen).

What is the mass of a 8.45 m3 piece of copper?

Answers

The mass of a 8.45 m3 piece of copper is 7537.4 grams.

What is mass?

Mass is described as a dimensionless quantity representing the amount of matter in a particle or object.

density of copper =8.92g/cm^3

volume = 8.45 x 100 cm^3

mass =  (8.45 x 100) x 8.92

mass = 7537.4 grams.

The relationship between mass, density and volume is that density offers a convenient means of obtaining the mass of a body from its volume or vice versa.

This means that the mass is equal to the volume multiplied by the density (M = Vd), while the volume is equal to the mass divided by the density (V = M/d).

What ions are formed with AgNO3 dissolves in water? How does water stabilize the ions?

Answers

Answer:

Explanation:

In water, silver nitrate (AgNO3) dissolves to generate the ions Ag+ (silver) and NO3- (nitrate). When the substance is dissolved in water, the ions are separated and become solvated, or surrounded by water molecules. Water molecules' oxygen atoms join the metal ion in a coordinate covalent bond that gives the metal ion a pair of electrons. By preventing it from interacting with other ions or molecules in the solution, this aids in stabilising the metal ion. As a result of their hydrogen bonds with the water molecules around them, the nitrate ions are likewise stabilised in solution.

What would be the electron configuration for neutral oxygen? Please show what energy level each electron is in using the electron diagonal filling rule do not use noble gas configuration.

Answers

Answer: 1s2 2s2 2p4

Explanation:

Recall the number of electrons an orbital can have:

s orbitals have 2, p orbitals have 6, d orbitals have 10, f orbitals have 14, and so on.

Oxygen in its neutral state would have 8 electrons.

To summarize the diagonal filling order, it goes from the least energy level to the most, and the orbital with the least amount of orbitals to the most.

So, the order for this will go from 1 and end at 2 (for energy level,) then s, s again (as energy level 1 has 1s orbital only,) and p.

So, the first energy level, 1s2 (2 electrons), leaves the remaining six electrons.

Completely fill the s orbital (another 2 electrons), and the remaining 4 electrons will be in the respective p orbital.

Thus, it is 1s2 2s2 2p4.

b. If you conducted an experiment and 11.5 grams of Fe(s) was formed what would be the percent yield?
c. If the percent yield for the process to obtain 75 kg of CO2 was 80.7%, how many kg of CO is needed?

Answers

The mass of the excess reactant ([tex]Fe_2O_3[/tex] that remains after the reaction would be 30.96 gramsThe percent yield would be 86.28%The amount of CO needed would be 59.14 kg.

Stoichiometric problems

From the balanced equation of the reaction, the mole ratio of the reactants is 1:3.

Mole of 50.0 g [tex]Fe_2O_3[/tex] = 50/160 = 0.3125 mol

Mole of 10.0 g CO = 10/28 = 0.3571 mol

Stoichiometric equivalent of  [tex]Fe_2O_3[/tex] = 0.3571/3 = 0.1190 mol

In other words,  [tex]Fe_2O_3[/tex] is in excess.

Excess mole = 0.3125 - 0.1190 = 0.1935 mol

Mass of 0.1935 mol [tex]Fe_2O_3[/tex] = 0.1935 x 160 = 30.96 grams

Mole ratio of CO to Fe = 3:2

Equivalent mole of Fe that would be formed = 0.3571 x 2/3

                                                                          = 0.2381 mol

Mass of 0.238 mol Fe = 0.238 x 56 = 13.328 grams

Percent yield of Fe = 11.5/13.328 x 100 = 86.28%

Mole of 75 gk CO2 = 75000/44 = 1704.55 mol

Mole ratio of CO2 and Co = 1:1

Equivalent mole of CO = 1704.55 mol

Mass of 1704.55 mol CO = 1704.55 x 28 = 47.73 kg

80.7% = 47.73 kg

100% = 100 x 47.73/80.7

        = 59.14 kg

In other words, 59.14 kg of CO would be needed.

RESOURCE: Access your online textbook through CLEVER, click to get the blue ribbon across the top of the page and go to the Table of Contents. Scroll down to Lesson 9 Conservation of Matter and select "Extending Your Knowledge: Mass and Matter"

Answers

Answer:

The Law of Conservation of Matter states that in a chemical reaction, matter is not created or destroyed. However, it is possible for the mass of a substance to change during a chemical reaction, as you observed.

When a substance burns, it reacts with oxygen in the air to form new compounds. For example, when wood burns, it reacts with oxygen to form water and carbon dioxide. The mass of the wood plus the mass of the oxygen is equal to the mass of the water and carbon dioxide produced.

In this case, the extra mass that you observed came from the oxygen that reacted with the wood. Oxygen has mass, and when it reacts with the wood, the mass of the resulting compounds is greater than the mass of the starting materials.

It's important to note that energy is not a form of matter, and therefore has no mass. However, energy can be converted into matter and vice versa, according to the famous equation E=mc^2, where E is energy, m is mass, and c is the speed of light. This equation demonstrates that mass and energy are fundamentally connected and can be converted into each other under certain conditions.

Answer:

C) W is the amplitude, and an increase in W is associated with an increase in energy.

Explanation:

A transverse wave consists of an oscillating electric field that is perpendicular to the direction of the wave. Increasing either the amplitude or the wavelength of the wave increases its energy. For a transverse wave, the amplitude corresponds to W, while the wavelength is labeled X. So increasing W or decreasing X will create increase the energy of the wave.

the enthaply of formation of water is -285.8kj/mol. what can be inferred from this statement

Answers

Answer:   It takes 285.8 kJ of energy to form one mole of water

Explanation:

The enthalpy of formation of a substance is the change in enthalpy that occurs when a substance is formed from its elements in their standard states. The enthalpy of the formation of water is -285.8 kJ/mol, which means that it takes 285.8 kJ of energy to form one mole of water from its elements (hydrogen and oxygen) under standard conditions. This value is negative, which means that the formation of water releases energy. This is why water is often referred to as an "exothermic" substance because it releases energy when it is formed. The negative value of the enthalpy of formation for water can be explained by the fact that the bonds formed between hydrogen and oxygen atoms in water are stronger than the bonds between hydrogen and oxygen atoms in the individual elements. This means that it takes less energy to break the bonds in the elements than it releases when the bonds in water are formed, resulting in a net release of energy.

This means that 285.8 kJ/mol is evolved when one mole of water is formed.

What is the enthalpy of formation?

The term enthalpy of formation has to do with the energy that is released or absorbed when a molecule of water if formed from its constituents.

The fact that the enthalpy of formation of water is -285.8 kJ/mol implies that 285.8 kJ/mol is evolved when one mole of water is formed.

Explanation:

The reaction below shows the combustion of propane (C3H8). Why is the mole ratio (3 moles CO2/1 mol C3H8) used to determine the amount of carbon dioxide (CO2) produced when propane (C3H8) combusts in excess oxygen? (1 point) C3H8 + O2 yields CO2 + H2O + heat Propane has a mass that is 3 times greater than that of CO2, so only 1 mole of C3H8 is needed to produce 3 moles of CO2. When the chemical equation for propane combustion is balanced, 1 mole of C3H8 is needed to produce 3 moles of CO2. During combustion, CO2 is approximately 3 times more reactive than C3H8, so less C3H8 will participate in the reaction. Carbon dioxide has a volume of about one-third that of C3H8, so 3 moles of CO2 are needed to react with each mole of C3H8.

Answers

One mole of the propane produces three moles of the carbon dioxide from mole ratio.

What is the mole ratio?

When we talk about the mole ratio, we mean the ratio of the species that can be found in the reaction. We can be able to get the mole ratio from the balanced reaction equation and we apply it to solve problems from the stoichiometry of the reaction.

Given the fact that we have the reaction as it has been written in the question, it is clear that we would need about one mole of the propane to produce three moles of carbon dioxide.

We can see that there are three atoms of carbon in the propane and the implication of this is that we are going to produce three atoms of carbon dioxide in the product.
