Jagdish 3 years, 8 months ago

Molecular orbital theory states that after forming molecule, electrons do not continue to revolve in atomic orbitals rather they start revolving in newly formed molecular orbitals which are around two or more nuclei of the participant atoms. It also explains the paramagnetic, diamagnetic properties as well as existence of some Diatomic molecules.

How to calculate enthalpy

Posted by Varun Kumar 3 years, 8 months ago

CBSE > Class 11 > Chemistry

1 answers

Rrrrr Rrrrr 3 years, 8 months ago

Use the formula ∆H = m x s x ∆T to solve. Once you have m, the mass of your reactants, s, the specific heat of your product, and ∆T, the temperature change from your reaction, you are prepared to find the enthalpy of reaction. Simply plug your values into the formula ∆H = m x s x ∆T and multiply to solve.
