I believe that the answer is element
Arrhenius Bases, so that other compounds that have the hydroxyl group (OH⁻)
hope this helps!
Answer:
872.28 kJ/mol
Explanation:
The heat released is:
ΔH = C*ΔT
where ΔH is the heat of combustion, C is the heat capacity of the bomb plus water, and ΔT is the rise of temperature. Replacing with data:
ΔH = 9.47*5.72 = 54.1684kJ
A quantity of 1.922 g of methanol in moles are:
moles = mass / molar mass
moles = 1.992/32.04 = 0.0621 mol
Then the molar heat of combustion of methanol is:
ΔH/moles = 54.1684/0.0621 = 872.28 kJ/mol
Answer:
I think
(d) All compounds contain the same elements in the same properties
Answer: Atom/element
Explanation: Since matter cannot be created or destroyed, the number of atoms has to be equal on both sides of the equation.
