Answer:

Answer is below with the steps in order

Explanation:

4) Blood picks up carbon dioxide from the body

7) Heart pumps carbon dioxide rich blood to the lungs

8) Inhale

9) Nose traps germs in air

10) Air moves down the trachea

3) Air moves through bronchi into the bronchioles

6) Alveoli receive oxygen pass to blood

9) Oxygen passes into the blood

11) Alveoli receives carbon dioxide from the blood

12) Oxygen-rcih blood flows to the heart

3) Carbon Dioxide moves from bonchioles to bronchi

13)Carbon dioxide flows up

1) Heart pumps oxygen-rich blood to the body

The last four of five steps could be switched up a little bit since it all happens synchronously, but this is the most accurate interpretation.

The statements in the correct order are:

The lungs and respiratory system allow us to breathe. They bring oxygen into our bodies (called inspiration, or inhalation) and send carbon dioxide out (called expiration, or exhalation). This exchange of oxygen and carbon dioxide is called respiration.

A metal is said to be an active metal when it reacts strongly and quickly with other elements due to the electrons in its structure and its ease of sharing the electrons with other elements. ... A metal's reactivity increases as we go from the top to the bottom of the periodic table.

Explanation:

A natural flow of ground water that has reached surface level is call a spring.

Water moves underground downward and sideways, in great quantities, due to gravity and pressure.

A spring is the result of an aquifer being filled to the point that the water overflows onto the land surface. They come in different sizes, from intermittent seeps, which flow only after much rain, to huge pools flowing hundreds of millions of gallons daily.

Answer:

We have the atoms, and we have the molar mass of Vanadium (listed in the periodic table) which should be 50.94g/mol.

The first step is to convert the 4.18 x 10^23 atoms into moles by dividing the atoms by Avogadro's number (6.02 x 10^23)  

(4.18 x 10^23)/(6.02 x 10^23) = 0.694 moles

Now we know that moles is equal to the mass divided by the molar mass. So now that we have the moles and the molar mass of Vanadium, we can rearrange the equation to find mass. Once you have rearranged it, you have to multiply the moles by the molar mass.

So 0.694 moles x 50.94g/mol = 35.35g of V

Answer:

Answer:

Fe₃PO₄

Explanation:

They have given the total mass of the compound, the mass of iron and the mass of phosphorus. So we can find the mass of oxygen.

Mass of oxygen = 12.17 - (7.77 + 1.44) = 2.96g

So we can now find the empirical formula.

Element - mass - Mr - Mass÷Mr - Ratio - Simplest Ratio

Fe - 7.77g - 55.8 - [7.77÷55.8] - [0.14÷0.05]  - 2.8 = 3

P   - 1.44g -   31   -   [1.44÷31]    - [0.05÷0.05] - 1

O  - 2.96g -   16  -   [2.96÷16]   - [0.19÷0.05]  - 3.8 = 4

[The simplest ratio was obtained by dividing the answer of mass÷mr with the smallest value. Phosphorus had the smallest value of mass÷mr=0.05, so all other answer were divided by 0.05]

Answer:

15 mol

Explanation:

the balanced equation is AgNO3 + NaCl > NaNO3 + AgCl.

the stequiometry of the reactions says: one mol of silver nitrate reacts with one one mol of silver chloride to produce one mol of silver nitrate and one mol of sodium chloride.

by proportions, if you have 15 mol of AgNO3 you're gonna have 15 mol of AgCl

From 15 mol of Silver nitrate, the moles of silver chloride produced have been 15 mol. Thus, option B is correct.

The balanced chemical reaction for the synthesis of silver chloride has been:

[tex]\rm AgNO_3\;+\;NaCl\;\rightarrow\;AgCl\;+\;NaNO_3[/tex]

From the balanced equation, since there has presence equal moles of silver nitrate and sodium chloride, the moles of silver chloride formed has been equivalent. Thus, 1 mole of silver nitrate gives 1 mole of silver chloride.

The moles of silver nitrate available are,  [tex]\rm M_A_g_N_O_3=15\;mol[/tex]

The moles of silver nitrate produced can be given as:

[tex]\rm 1\;mol\;AgNO_3=1\;mol\;AgCl\\15\;mol\;AgNO_3=15\;\times\;1\;mol\;AgCl\\15\;mol\;AgNO_3=15\;mol\;AgCl[/tex]

Thus, the moles of silver chloride produced have been 15 mol. Thus, option B is correct.

87 picograms are equivalent to [tex]8.7\times 10^{-11}[/tex] grams.

This is a unit problem, in which a derived unit must translated into a fundamental unit. A picogram is a equivalent to a trillionth of a gram, which is the fundamental SI mass unit. Mathematically speaking, we have the following equivalence:

[tex]1\,pg = 1\times 10^{-12}\,g[/tex]

Now we proceed to find the equivalent value for this case:

[tex]87\,pg[/tex]

[tex]87\times 10^{-12}\,g[/tex]

Answer:

3, why because most of the time chemicals reacts within eachother to make new compound that's may lead the liquid chemicals to deflect some of the spectrom of light like red,yellow,blue

To solve such this we must know the concept of chemical reaction. There are so many ways to identify the chemical reaction. Therefore the correct options are option 3, 5.

Chemical reaction is a process in which two or more than two molecules collide in right orientation and energy to form a new chemical compound. The mass of the overall reaction should be conserved that is mass can nether be created nor be destroyed in a chemical reaction.

There are so many types of chemical reaction reaction like combination reaction, double displacement reaction. The evidence of a chemical reaction are  "the liquid turned pink when mixed" and "over time, a white solid formed at the bottom of the beaker".

Therefore the correct options are option 3, 5.

Answer:

B.chlorine ,Cl2 is the one

Molecules are formed when two or more atoms chemically bond together. In 3H₂(SO)₄, three molecules are present.

Molecules are the smallest unit present in any compound and are formed by a group of atoms. A number denoted in front of the chemical species is the coefficient that represents the number of molecules.

The coefficient present in front of the reactant or the product in a chemical reaction gives the number of the molecules present in a compound. As three is denoted in front of the sulphuric acid, hence will be the number of the molecules.

Therefore, there are three molecules present in sulphuric acid.
