What is Br2 in chemistry?
Bromine compound
Bromine compound is a molecule formed when two bromine atoms combine together. Bromine (Br2) is a red-brown liquid at ordinary temperature. It is very volatile.
How do you find enthalpy?
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.

What is Q MC ∆ T used for?
The amount of heat gained or lost by a sample (q) can be calculated using the equation q = mcΔT, where m is the mass of the sample, c is the specific heat, and ΔT is the temperature change.
How do you calculate the enthalpy of a solution?
Heat of Solution or Enthalpy of Solution Chemistry Tutorial
- Step 1: Calculate the amount of energy released or absorbed (q) q = m × Cg × ΔT.
- Step 2: Calculate moles of solute (n) n = m ÷ M.
- Step 3: Calculate mount of energy (heat) released or absorbed per mole of solute (ΔHsoln) ΔHsoln = q ÷ n.
What is the bond enthalpy equation?
Bond Enthalpy – Key takeaways Enthalpy values use the mean bond energy which is an average over different molecules. We can use the mean bond energy to calculate the ΔH of a reaction by using the formula: ΔH = Σ bond energies broken – Σ bond energies made.
