Answer:
50kg
Explanation:
Using the formula for potential energy, which is the amount of energy due to position;
P.E = m × g × h
Where;
m = mass (kg)
g = acceleration due to gravity (10m/s²)
h = height (metres)
According to the information provided in this question, m = ?, P.E = 2500J, h = 5m
Using P.E = m × g × h
m = P.E/gh
m = 2500/(5 × 10)
m = 2500/50
m = 50kg
The mass of the man is 50kg.

Answer:
FeSO₄ + 2NaOH → Fe(OH)₂ + Na₂SO₄
Explanation:
The equation for the reaction is:
FeSO₄ + 2NaOH → Fe(OH)₂ + Na₂SO₄
Dissociation of each compound
FeSO₄ → Fe²⁺ + SO₄⁻²
NaOH → Na⁺ + OH⁻
Fe(OH)₂ → Fe²⁺ + 2OH⁻
Na₂SO₄ → 2Na⁺ + SO₄⁻²
