The answer is <span>1.63 × 1024 atoms Fe.

Avogadro's number is the
number of units (atoms, molecules) in 1 mole of substance:
<span>6.023 × 10²³ atoms per 1 mole
</span>So, how many atoms are per 2.70 moles:
6.023 × 10²³ atoms : 1 mole = x : 2.70 moles
x = 6.023 × 10²³ atoms * 2.70 moles : 1 mole
x = 16.3 × 10²³ = 1.63 × 10 × 10²³ = 1.63 × 10²⁴ atoms
Answer:
Reduction
Explanation:
The charge on Mg goes from 2+ to 0 which means this is a reduction.
C because a compound is a substance made of at least two atoms bonded together
Waves travel through matter, so I am 99.9% sure that is the answer.
Id look through your lesson to be sure!
