Answer:
Cp = 0.237 J.g⁻¹.°C⁻¹
Explanation:
Amount of energy required by known amount of a substance to raise its temperature by one degree is called specific heat capacity.
The equation used for this problem is as follow,
Q = m Cp ΔT ----- (1)
Where;
Q = Heat = 640 J
m = mass = 125 g
Cp = Specific Heat Capacity = <u>??</u>
ΔT = Change in Temperature = 43.6 °C - 22 °C = 21.6 °C
Solving eq. 1 for Cp,
Cp = Q / m ΔT
Putting values,
Cp = 640 J / (125 g × 21.6 °C)
Cp = 0.237 J.g⁻¹.°C⁻¹
It’s a combustion reaction but what are you trying to find?
The correct answer is letter B. Genetic engineering has shown a great leap in Science because we can now harness the ability of mutations of cells in crops and in other aspects. Flour is a commodity that is greatly needed by the masses and learning how to genetically modify its components to help it breed better is a great advantage for any society.
