Write balanced equations for the following reactions (a) reaction between magnesium (mg) and nitrogen (n.) to form mg n, at high a temperature. (b) reaction between mgan, and water to form magnesium hydroxide and ammonia (nh) (c) decomposition of magnesium hydroxide when it is strongly heated. see step 22 of the procedure for the products formed in this reaction.] a sample of 0.756 moles of propane (ch) is completely burned in 1.95 moles of oxygen. the products are carbon dioxide and water. (a) write the balanced equation. (b) which is the limiting reactant? (show calculations) (c) how many moles of water are produced during this reaction? (show calculations) (d) which is the excess reactant? how much of the excess reactant remains unreacted?
