How many atoms are there in 0.57 mol of Zn
AfilCa [17]

Answer:

3.43 * 10^23 atoms of zinc

Explanation:

According to Avogadro's law, one mole of a substance contains a certain number of atoms of the substance commonly referred to as the Avogadro's number.

We already know from Avogadro's law that;

1 mole of zinc contains 6.02 * 10^23 atoms of zinc

Therefore;

0.57 mole of zinc will contain 0.57 * 6.02 * 10^23/1

which gives us 3.43 * 10^23 atoms of zinc

What are some chemical changes that occur at school at home and in nature
Travka [436]

Chemical changes are irreversible.

A chemical change that could happen at school would be when you have a chemistry experiment and you mix an acid and a base such as mixing hydrochloric acid with sodium hydroxide.

A chemical change that could happen at home would be baking a cake. You can't take the ingredients used in baking a cake back apart because they have changed their chemical composition.

A chemical change that happens in nature could be a forest fire. The burning of wood would be the chemical change in this case.
