1. How much heat is gained by nickel when 29.2 g of nickel is warmed from 18.3°C to 69.6°C? The specific heat of nickel is 0.443 J/(g · °C

THE HEAT REQUIRED TO RAISE 29.2 G OF NICKEL BY 51.3 °C IS 663.60 J

Explanation:

Mass of nickel = 29.2 g

Temperature change = 69.6 °C -  18.3°C = 51.3 °C

Specific heat of nickel = 0.443 J/g °C

Heat = unknown

The heat of reaction of nickel is the amount of heat needed to raide a unit mass of nickel by 1 °C

Mathematically.

heat = mass * specific heat * change in temperature

Heat = m C ΔT

Heat = 29.2 * 0.443 * 51.3

Heat = 663.596 J

The heat needed to raise 29.2 g of nickel by 51.3 °C is approximately 663.60 J

your answer is c) plasma
