Answer:
Explanation:
1 mole = 6.02x10^23
32.3x10^24/6.02x10^23= 53.65449 moles
53.65449 moles
Most teachers force you to worry about significant figures
53.65 moles
Idk if it is multiple choice but if it is it is the first two, if it is a single answer then it is the first one
Answer:
Reactants disappear while the Products appear
Explanation:
Answer:
Sn²⁺ + Tl³⁺ → Sn⁴⁺ + Tl⁺
Explanation:
The Sn²⁺ is oxidized to Sn⁴⁺. Whereas Tl³⁺ is reduced to Tl⁺. The half-reactions are:
Sn²⁺ → 2e⁻ + Sn⁴⁺ (Oxidation, loosing electrons)
Tl³⁺ + 2e⁻ →Tl⁺ (Reduction, gaining electrons)
The sum of the reactions gives:
Sn²⁺ + Tl³⁺ + 2e⁻ → 2e⁻ + Sn⁴⁺ + Tl⁺
Subtracting the electrons in both sides of the reaction:
<h3>Sn²⁺ + Tl³⁺ → Sn⁴⁺ + Tl⁺</h3>
The answer is A because it does not represent a redox reaction
