By the time thermal equilibrium is attained in the system, ice is completely converted to water.

Thermal equilibrium is a situation in which two substances are exactly at the same temperature. That is. Heat is no longer flowing beween the bodies.

Recall that an insulated thermos flask implies that heat does not eneter or leave the system. Heat will flow from the water to the ice untill the both  attains the same temperature and the ice is completely converted to water.

Answer:

Explanation:

Both Sample A and B have the same mass (5g) and same temperature change (15°C). What is not said and may explain the difference in energy needed are their initial states and temperature.

For example Sample B may be liquid water at 90°C. Heating it up to 105°C will require additional energy to go from liquid to gas state. If Sample A is water vapor at 105°C at first, it has a lower specific heat and heating it up to 120°C does not involve a state change. So the eneregy needed is less.

Using accurate measurements, using pure chemicals and performing the reaction under the most ideal conditions is important to get a valuable percent yield.

Percent yield of any chemical reaction is define as the ratios of the actual yield to the theoretical yield of the product and multiply by the 100.

To get the high percent yield or actual yield of any reaction, we have to perform the reaction under ideal condition because if we not use the standard condition then we get the low rate of reaction. Reactants should be present in the pure form as impurity make unwanted products and reduce the productivity of main product and accurate amount of reactants also important for the spontaneous reaction.

Hence, options (a), (b) & (c) are correct.

[tex]mass = number \: of \: moles \times molar \: mass[/tex]

[tex]m = 2.36(223.2) = 526.752 \: grams[/tex]

[tex]n = \frac{mass}{molar \: mass} = \frac{23.5}{58.4} = 0.40239 \: moles[/tex]

[tex]n = \frac{0.778}{49} = 0.0158775 \: moles[/tex]

[tex]n \: o \: p = 0.0455 \times 6.02 \times 10 {}^{23} = 2.7391 \times 10 {}^{22} particles[/tex]

Mass in grams of 2.360 moles of lead (II) oxide is 0.0105.

Avogadro's number is the number of units in one mole of any substance and equals to 6.02214076 × 10²³. The units can be electrons, atoms, ions, or molecules.

No. of moles is defined as a particular no. of particles that we can calculate with the help of Avogadro’s number.

Mass of a particular product is also find out by stoichiometry of a reaction as per the no. of mole given in the reaction.

Given, No. of moles of lead oxide = 2.360 grams

No. of moles = Mass of compound ÷ Molar mass of compound

No. of moles = 2.36 ÷ 223.2

No. of moles = 0.0105

Therefore, Mass in grams of 2.360 moles of lead (II) oxide is 0.0105.

This is the mass number A. It shows the number of nucleons (neutrons and protons in the nucleus). It is made up of the atomic number Z and the neutron number N:

A = Z + N

Using the example of helium:

Helium has a mass number A of 4 and the atomic number Z 2, so the atom has 2 neutrons in its nucleus.

A = Z + N

4 = 2 + 2

Dalton's 5 postulates

All matter consists of indivisible particles called atoms.

Atoms of the same element are similar in shape and mass, but differ from the atoms of other elements.

Atoms cannot be created or destroyed.

Atoms of different elements may combine with each other in a fixed, simple, whole number ratios to form compound atoms.

Explanation:

Photosynthesis is that plant process is affected most during this darkness because photosynthesis only occurs when there is sunlight.

Photosynthesis is a process in which water and carbondioxide combine in the presence of sunlight and produce glucose and oxygen. We know that Photosynthesis occurs only at daytime.

So we can conclude that Photosynthesis is affected during this darkness because photosynthesis only occurs when there is sunlight.

Answer: Five moles of CH4 would require ten moles of O2.

Explanation: Start with a balanced equation. You can see from the balanced equation that one mole of CH4 reacts completely with two moles of O2. So five moles of CH4 would require ten moles of O2.

Answer:

C6 H10 O5+ 6O2-----> 6CO2+5H2O+heat

Explanation:

There are 6 carbon atoms in reactants to balance you put coefficient 6.

This makes the oxygen in CO2 12 so to balance put 6 in oxygen in reactants.

There are 10 hydrogen atoms in reactants to balance you put 5 in front of H2O in products.

If u recheck: 6 C atoms in reactants, 6 C atoms in products.

10 H atoms in reactants, 10 H atoms in products.

17 O atoms in reactants, 17 O atoms in products.

The new volume of the gas at a temperature of 273 K and at pressure of 101.33 KPa is 706.01 L

The new volume of the gas can be obtained by using the combined gas equation as illustrated below:

P₁V₁ / T₁ = P₂V₂ / T₂

(303.98 × 250) / 290 = (101.33 × V₂) / 273

Cross multiply

290 × 101.33 × V₂ = 303.98 × 250 × 273

Divide both side by 290 × 101.33

V₂ = (303.98 × 250 × 273) / (290 × 101.33)

V₂ = 706.01 L

The atomic mass unit is equivalent to 1 of the mass of a neutral atom of carbon.

It is defined as one out of twelve parts of the mass of the neutral atom of the most abundant isotope of carbon, that is, carbon 12.

By this definition, it is obvious that the atomic mass unit of elements is measured with respect to the mass of a neutral atom of carbon 12 - not hydrogen, gold, or oxygen.
