The electrons determine chemical behavior
There are six atoms of oxygen in that compound.
Shorter showers, hand washing dishes, rewearing clothing if it isn’t too dirty, not letting the sink run while brushing teeth, eco friendly toilet.
Answer:
Explanation:
maleic acid ⇒ fumaric acid
ΔHreaction = ΔHproduct - ΔHreactant
ΔHproduct = -1336.0 kJ mol⁻¹
ΔHreactant = - 1359.2 kJ mol⁻¹.
ΔHreaction = -1336.0 kJ mol⁻¹ - ( - 1359.2 kJ mol⁻¹.)
= 1359.2 kJ mol⁻¹ -1336.0 kJ mol⁻¹
= 23.2 kJ mol⁻¹ .
Enthalpy of isomerization from maleic to fumaric acid is 23.2 kJ per mol.
Answer:
Explanation:
Hello there!
In this case, since the heat of fusion is a property that allows us to calculate the heat involved during the change from solid to liquid (fusion) and is calculated as shown below:
In such a way, given the heat involved during this process and the mass of copper, we calculate the heat of fusion as shown below:
Or in kJ/mol:
