Hope this helped thanks u
The chemical reaction would be:
HBr + LiOH = LiBr + H2O
We are given the concentration of the other reactant. We use these given values and the reaction to relate to moles of HBr needed. We do as follows:
0.253 mol / L ( .005 L) ( 1 mol HBr / 1 mol LiOH ) = 0.0013 mol HBr
Molarity = 0.0013 / 0.01 = 0.13 M
38 g / (3 x 10^23 molecules) * 6,02x10^23 molecules/mol = 76,25 g/mol.
Answer:
The difference between the energy of the reactants and the energy of the products is called the enthalpy change (∆H) of the reaction. For an exothermic reaction, the enthalpy change is always negative. In an endothermic reaction, the products are at a higher energy than the reactants.
