Ahydrocarbon sample was burned in a bomb calorimeter. the temperature of the calorimeter and the 1.00 kg of water rose from 20.45°c to 23.65°c. the heat capacity of the calorimeter, excluding the water, is 2.21 kj/°c. using this information, determine the heat released by the combustion.

The heat released by the combustion is 20,47 kJ

Explanation:

Bomb calorimeter is an instrument used to measure the heat of a reaction. The formula is:

Q = C×m×ΔT + Cc×ΔT

Where:

Q is the heat released

C is specific heat of water (4,186kJ/kg°C)

m is mass of water (1,00kg)

ΔT is temperature change (23,65°C - 20,45°C)

And Cc is heat capacity of the calorimeter (2,21kJ/°C)

Replacing these values the heat released by the combustion is:

Q = 20,47 kJ

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates
