Chemistry is composed of many sub-disciplines such as inorganic chemistry, physical chemistry, biochemistry, organic chemistry, analytical chemistry etc. The following is a matching of certain projects against the sub-discipline in chemistry where they rightfully belong.

1) Determine the composition of a moon rock sample..... analytical chemistry

2) Do research on making a new medicine to treat high blood pressure..... biochemistry

3)  Investigate ways to regulate the rate of gasoline burning in an automobile engine......physical chemistry

4) Develop a plastic that can be decomposed by bacteria......organic chemistry

5) Improve the method for extracting iron from iron ore.....inorganic chemistry

The sub-disciplines of chemistry all work together to make the world a better place. The science of chemistry is very pivotal hence it is applicable in every area of science and technology.

Analytical chemistry, as the name implies, deals with "analyzing" or finding out the components of materials.

Biochemistry is concerned with the study of molecules that have biological activity such as medicine to treat high blood pressure.

One key area of physical chemistry is chemical kinetics which discusses rates of chemical reactions. This sub-discipline is important when investigate ways to regulate the rate of gasoline burning in an automobile engine.

Organic chemistry is the chemistry of carbon compounds. It studies compounds that contain long chains of carbon such as those found in plastics.

Inorganic chemistry deals with the study of the elements including the extraction of elements such as iron from its ore.

When 25.0 g of ch4 reacts completely with excess chlorine yielding 45.0 g of ch3cl, what is the percentage yield, according to c
snow_tiger [21]

Percentage yield = (actual yield / theoretical yield) x 100%<span>

The balanced equation for the reaction is,
    CH₄(g) + Cl₂<span>(g) </span>→ CH₃Cl(g) + HCl(g)</span><span>

Since there is excess of Cl₂ gas, we can assume that all of CH₄ gas are reacted.</span><span>

Moles of CH₄(g) = mass / molar mass</span><span>
                           = 25.0 g / 16 g/mol
                           = 1.5625 mol

The stoichiometric ratio between CH₄(g) and CH₃Cl(g) is 1 : 1</span><span>

Hence moles of CH₃Cl(g) = 1.5625 mol</span><span>

Molar mass of CH₃Cl(g) = 50.5 g/mol</span><span>
 
Mass of CH₃Cl(g) = number of moles x molar mass</span><span>
                             = 1.5625 mol x 50.5 g/mol
<span>                             = 78.9 g</span>
Hence theoretical yield = 78.9 g
Actual yield = 45.0 g

Hence,
<span> Percentage yield = (45.0 g / 78.9 g) x 100% </span>
<span>                             = 57.03%</span></span>

<em>Nothing happens</em>; water is still H₂O, even if it turns into ice, or vapor. Although, the molecules still move around faster, just like a normal gas would.

Compare 1 mole of H2, 1 mole of O2 and 1 mole of F2
likoan [24]

Explanation:

(a)  As per the mole concept, one mole of any atom contains 6.022 \times 10^{23} atoms or molecules, that is, Avogadro's number of atoms.

Therefore, 1 mole of H_{2} = 2 \times 6.022 \times 10^{23} molecules

                                           = 1.2044 \times 10^{23} molecules

   1 mole of O_{2} = 2 \times 6.022 \times 10^{23} molecules

                                    = 1.2044 \times 10^{23} molecules

   1 mole of F_{2} = 2 \times 6.022 \times 10^{23} molecules

                                    = 1.2044 \times 10^{23} molecules

Hence, there are equal number of molecules present in the given atoms.

(b)   Mass of each given atom will be calculated as follows.

                Mass = no. of moles × molar mass

As one molecule of H_{2} contains 2 atoms of hydrogen.

So, mass of 1 mole of H_{2} = 2 mol \times 1.008 g/mol

                                                     = 2.016 g

      mass of 1 mole of O_{2} = 2 mol \times 15.999 g/mol

                                                     = 31.996 g

      mass of 1 mole of F_{2} = 2 mol \times 18.998 g/mol

                                                     = 37.996 g

Thus, we can conclude that F_{2} has the greatest mass.
