STOICHIOMETRY:

1. Solutions of ammonium chloride and potassium hydroxide are mixed. Ammonia, potassium chloride, and water are produced. You have 1.46g of ammonium chloride in solution and 1.08g of potassium hydroxide in solution. If the experiment yields 0.406g of water, what is the percent yield?

(I don't how to start, help!)

To save time, you can approximate the initial mass of the solid to the nearest ±1 g. for example, if you are asked to add 14.3 g of copper, add between 13 g and 15 g. which of the following sets include two samples with an equal density? which all that apply below 15.4 g gold and 18.7 g silver 15.2 g copper and 50.0 g copper 20.2 g silver and 20.2 g copper 11.2 g gold and 14.9 g gold

Is this correct if not can u correct me

Use the periodic table to determine how many grams of oxygen would be required to react completely with 859.0 g c2h2
