Determine if the following reactions are exothermic or endothermic.

Choose the strong acids from the following (there may be more than one). 

A lab has a stock solution of 7.50 M hydrochloric acid. A scientist needs 0.750 L of 0.354 M hydrochloric acid, how many milliliters of the stock solution does the scientist need to use? 

For the following hypothetical reaction how much heat is released in kilojoules (kJ) if 210.0 g of propanol (C3H7OH ) is added to excess oxygen?   

If 21.2 g of chlorine gas reacts with 24.5 g of sodium iodide what is the limiting reagent and how much sodium chloride can be produce?

Which of the following pHs is the most basic?

If 42.0 mL of 0.631 M lead (II) nitrate, (Pb(NO3)2), is reacted with excess potassium chloride, (KCl), how many grams of lead (II) chloride (PbCl2) will be produced? 

Sodium is a very reactive metal that reacts with water to produce sodium hydroxide and hydrogen gas. If 12.6 g of sodium reacts with excess water how much hydrogen gas (in grams) can be produced? 

If 93.0 mL of 0.811 M lead (II) nitrate, (Pb(NO3)2), is reacted with excess potassium chloride, (KCl), how many grams of lead (II) chloride (PbCl2) will be produced?
