redox reactions of metals with acids are described to oxidize the metal and generate hydrogen gas and an aqueous solution of ions. suppose 3.50 g of magnesium metal is dropped into 0.150 l of 6.00 m hcl in a 5.00 l cylinder at 25.0 oc whose initial gas pressure is 1.00 atm, and the cylinder is immediately sealed. find the final total pressure in the cylinder in atm.
