Calculate the heat of combustion of a compound if o.06 mole of burning raise the temperature of 40.0gm of water by 10k ( specfic heat of water=4.2
To calculate the heat of combustion, you need to use the equation:
q = m * c * ΔT
where:
q = heat energy
m = mass of water
c = specific heat of water
ΔT = change in temperature
Given:
m = 40.0 g
c = 4.2 J/g·K
ΔT = 10 K
n = 0.06 moles (quantity of the compound)
To convert the moles to grams, you need to know the molar mass of the compound.
Once you have the molar mass, you can calculate the mass of the compound:
mass of compound = n * molar mass
Then you can use the calculated mass of the compound in the heat equation to determine the heat of combustion.
Let's assume the molar mass of the compound is 100 g/mol.
mass of compound = 0.06 mol * 100 g/mol = 6 g
Now, you can substitute the values into the heat equation:
q = (mass of water) * (specific heat of water) * (change in temperature)
q = (40.0 g) * (4.2 J/g·K) * (10 K)
q = 1680 J
Therefore, the heat of combustion of the compound is 1680 J.
