Please, if you could help me with any of these problems! THANKYOU!
9.If the atmospheric pressure is 790 torr, what is it in atmospheres?
13.Given the equation Mg + 2HCl ïƒ* MgCl2 + H2 . How many grams of H2 are formed if 5 g of Mg react with excess HCl?
14.In the reaction Mg + 2HCl ïƒ* MgCl2 + H2 How many grams of H2 ar
16.A solution is made by dissolving 15 g of NaCl in distilled water and diluting to exactly 350 mL. What is the molarity of the solution?e formed if 2 moles of Mg react with excess HCl?
26.A sealed flask contains a mixture of 2.0 moles of gas A and 3.0 moles of gas B. If the total pressure of this gas mixture is 8.0 atmospheres, what is the partial pressure of gas A?
Remember, you don't have to answer them all. If you can even help me with one, that would be great!! God bless!
