Hii!! need help with this last answer for chem. would appreciate the help. (question 3)
avanturin [10]

Answer:

1.023 J / g°C

Explanation:

Mass, m = 37.9 g

Temperature increase (change) = 25.0°C

Heat = 969 J

Specific heat capacity ,  c= ?

The relationship between these quantities is given by the equation;

H = mcΔT

c = H / mΔT

c = 969 / (37.9 * 25)

c = 969 / 947.5 = 1.023 J / g°C

You have a 15.0 gram sample of gold at 20.0°C. How much heat does it take to raise the temperature to 100.0°C?
Nadusha1986 [10]

Answer:

=154.8 J

Explanation:

The rise in temperature is contributed by the change in temperature.

Change in enthalpy = MC∅,  where M is the mass of the substance, C is the specific heat capacity and ∅ is the change in temperature.

Change in temperature = 100.0°C-20.0°C=80°C

ΔH=MC∅

The specific heat capacity of gold= 0.129 J/g°C

ΔH= 15.0g×0.129J/g°C×80°C

=154.8 J
