If a 500 gram block of metal absorbs 5,016J of heat when its temperature changes from 20.00 Celsius to 45 Celsius what is the sp
ryzh [129]
The specific heat is 0.401 J/(g x C). The specific heat is the amount of heat of one unit mass of an object required to raise the temperature by one degree Celsius. The specific amount can be calculated using Cp = Q/(m x changes in T) formula, where Cp is the specific heat, Q is the amount of heat, m is the object's mass, and changes in T is the changes in temperature<span>.</span>

Silver nitrate reacts with calcium to make calcium nitrate and silver. The reaction is exothermic and produces 18.7 kJ/mol of en
denis-greek [22]

Answer:

1.63 kilo Joules of energy will be produced when 14.8 g of silver nitrate react.

Explanation:

AgNO_3+Ca\rightarrow Ag+CaNO_3,\Delta H_{rxn}=-18.7 kJ/mol

Mass of silver nitrate = 14.8 g

Moles of silver nitrate = \frac{14.8 g}{170 g/mol}=0.08706 mol

According to reaction, when 1 mole of silver nitrate reacts with 1 mole of calcium it gives 18.7 kJ of heat.

Then amount of heat released when 0.08706 moles of silver nitrate reacts :

0.08706\times 18.7 kJ=1.628 kJ\approx 1.63 kJ

1.63 kilo Joules of energy will be produced when 14.8 g of silver nitrate react.
