Calculate the [h3o+] of an aqueous solution that is 2.42 × 10−7 m in oh−.

When 225mg of anthracene, c14h10(s), was burned in a bomb calorimeter the temperature rose by 1.75k. calculate the calorimeter constant. by how much will the temperature rise when 125mg of phenol, c6h5oh(s), is burned in the calorimeter under the same conditions? (δch< (c14h10,s)=–7061 kj mol−1.)

What is the relation between concentration of reactants and the rate of chemical reaction?

Calculate the number of molecules present in 0.750 mol of mgo.
