<span>Answer is 6.66 mol.
<em>Explanation:</em>
According to the
Avogadro's constant, 1 mole of substance has 6.022 × 10²³ particles.
Number of Zinc atoms = </span>4.01 x 10²⁴
Avogadro's constant = 6.022 × 10²³ mol⁻¹
Hence,
moles of Zinc = number of Zinc atoms / Avogadro's constant
= 4.01 x 10²⁴ / 6.022 × 10²³ mol⁻¹
= 6.66 mol

The controlled variable is the variable that remains the same throughout the whole experiment. Here, the warm water and the same dishes are the same throughout the whole experiment- so they are the controls
Answer:
KOH (aq) + HC2H3O2 (aq) → H2O (l) + KC2H3O2 (aq)
Explanation:
When acetic acid react with potassium hydroxide, it will produce potassium acetate and water according to the equation below:
KOH (aq) + HC2H3O2 (aq) → H2O (l) + KC2H3O2 (aq)
