Pleas help me!

Answer:

Explanation:

Question 1:

atomic number/number of protons

All atoms of the same element share the same number of protons or atomic numbers. In grouping elements on the periodic table, the periodic law is often used. The modern periodic law states that "properties of elements are a periodic function of their atomic number". The atomic number of an element distinguish it from others.

Question 2:

The two carbon atoms would be quite different as they are isotopes. Isotopy is the existence of two or more atoms of the same element having  the same atomic number but different mass numbers due to the differences in the number of neutrons in their various nuclei.

Naturally, carbon exists in two isotopic forms:

                        ¹³₆C and ¹⁴₆C

One might see these different samples in a rock and in the skin cells. They are simply isotopes. Isotopes have the same electronic configuration and hence similar chemical properties. Only their masses differ.

Apply the law of conservation of mass to explain how mass is conserved when water evaporates 
frutty [35]
The law of conservation holds that mass can not be destroyed but can only take on different forms. So if 5 g of water becomes a gas it becomes 5 g of water vapor. The mass of the liquid water is simply transferred into the mass of the newly formed water vapor.
