One of the most important social reforms of the Jacobins was the abolition of slavery in French colonies. The slave trade began in the 17th century. The Convention in 1794 said to free all slaves in France. 10 years later, Napoleon reintroduced slavery. Plantation owners now understood their freedom & Slavery was finally abolished in French colonies in 1848.

Electricity is a secondary energy source that we get from the conversion of other sources of energy such as coal, natural gas, oil, nuclear power, and so on. These sources are known as “primary sources.” Primary sources can be renewable or non-renewable, but the electricity itself is neither.

Rrrrr Rrrrr 4 years, 11 months ago (10790488)

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.
