Why is a saturated solution of magnesium hydroxide less basic than a saturated solution of potassium hydroxide? A.) magnesium hydroxide is less soluble than potassium hydroxide

B.) magnesium is less basic than potassium

C.) magnesium hydroxide solutions are just as basic as potassium hydroxide solutions

D.) when magnesium hydroxide dissolved the hydroxide ion is partially neutralized

The combustion of methane, ch4, releases 890.4kj/mol. that is, when one mole of methane is burned,890.4 kj are given off to the surroundings. this meansthat the products have 890.4 kj less than the reactants.thus, ah for the reaction = - 890.4 kj. a negative symbolforah indicates an exothermic reaction.ch (g) + 20 (g)> co2 (g) + 2 h0 (1); ah = - 890.4 kga) how much energy is given off when 2.00 mol of ch,are burned? b) how much energy is released when 22.4g of ch. areburned?
