Chemistry
1 answer:
AfilCa [17]3 years ago
8 0

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

Rudiy27

Answer:

The mouth uses both mechanical and chemical digestion. Mechanical digestion involves physically breaking down the food into smaller pieces (using the jaw/teeth). However, chemical digestion then takes over and starts breaking down the food into simpler nutrients that can be used by the cells using saliva, which is naturally made within the mouth.

Hope this helps you! Have a great day! :D
