If 75.2 mL of 0.25 M HCl(aq) reacts with an excess of Mg(OH)2(aq), what mass of magnesium chloride could be produced? and What mass of water could be produced?

What type of reaction is shown below? check all that apply. 2h2o2 → 2h2o + o2 synthesis decomposition combustion

Chemistry worksheet - i am not sure what they are asking for exactly?

Hydrogenation reactions, in which h2 and an "unsaturated" organic compound combine, are used in the food, fuel, and polymer industries. in the simplest case, ethene (c2h4) and h2 form ethane (c2h6). if 140 kj is given off per mole of c2h4 reacting, how much heat (in mj) is released when 12 kg of c2h6 forms?
