how many grams of water would require 22000 joules of heat to raise its temperature from 34 C to 100 C. THe specific heat of water is 4.2 j/g C
The mass of water required to raise 22000 joules of heat from a temperature of 34°C to 100°C is 79.37g.
How to calculate mass?The mass of a substance can be calculated by using the following formula:
Q = m × c × ∆T
Where;
Q = quantity of heat absorbed or releasedm = mass of substancec = specific heat capacity∆T = change in temperature22000 = m × 4.2 × (100 - 34)
22000 = 277.2m
m = 22000/277.2
m = 79.37g
Therefore, the mass of water required to raise 22000 joules of heat from a temperature of 34°C to 100°C is 79.37g.

620
25.5
The molar enthalpy of combustion in kj/mol of magnesium is 620 kj/mol, Option D is the correct answer.
What is enthalpy of Combustion ?The energy released when a fuel is oxidized by an oxidizing agent is called enthalpy of Combustion.
It is given that
a 1.0 g sample of magnesium is burned to form MgO. in doing so, 25.5 kj of energy are released.
Molecular weight of Magnesium = 24.35g
24.35 g makes 1 mole of Mg
1g = 1/24.35
For 0.04 moles 25.5 kJ is released
for 1 mole 25.5 *1/.04
= 620 kj/mol
Therefore the molar enthalpy of combustion in kj/mol of magnesium is 620 kj/mol.
