Suppose that 0.524 g of Mg is reacted with 60.0 mL of 1.0 M H+. Assume that the density of the H+ solution is 1.00 g/ml and that its specific heat capacity equals that of water. The initial and final temperatures are 22.0 C and 65.8 C.
Calculate the ΔH of the reaction per mole of magnesium.
Based on the molecular formula, determine whether each of the following is an alkane, alkene, or alkyne. (Assume that the hydrocarbons are noncyclical and there is no more than one multiple bond.)
3.5 g of a hydrocarbon fuel is burned in a vessel that contains 250. grams of water initially at 25.00 C. After the combustion,the temperature of the water is 26.55 C.
Lithium iodide has a lattice energy of -7.3 times 10^2kJmol and a heat of hydration of -793kj/mol. Find the heat of solution for lithium iodide.
