This is a redox reaction where oxidation and a reduction occur.

<span>Here, Mg goes to Mg²</span>⁺ <span>by changing its oxidation number from 0 to +2 while S goes to S²</span>⁻ <span>by reducing its oxidation state from 0 to -2 . Hence Mg is oxidized by S in the reaction.</span>

 

Reducing agent <span>is a substance which reduces other substance by oxidizing itself. Hence, the reducing agent of this reaction is <span>Magnesium.</span></span>

Determine which equations you would use to solve the following problem: Calculate the amount of heat needed to change 20.0 g of
Inessa [10]

Answer:

Q = 4019.4 J

Explanation:

Given data:

Mass of ice = 20.0 g

Initial temperature = -10°C

Final temperature = 89.0°C

Amount of heat required = ?

Solution:

specific heat capacity of ice is 2.03 J/g.°C

Formula:

Q = m.c. ΔT

Q = amount of heat absorbed or released

m = mass of given substance

c = specific heat capacity of substance

ΔT = change in temperature

ΔT = T2 - T1

ΔT =  89.0°C - (-10°C)

ΔT = 99°C

Q = 20.0 g ×2.03 J/g.°C × 99°C

Q = 4019.4 J
