Balanced Equation of magnesium metal with hydrochloric acid: Mg+2HCl --> MgCl2+H2
Balanced Equation of magnesium oxide with hydrochloric acid: MgO+2HCl --> MgCl2+H2O
Combine the above two equations with that for the formation of liquid water and use addition and/or subtraction(i.e. Hess's Law) to arrive at the equation for the formation of magnesium oxide. Show work please.
Determine the molarity of a solution of twenty grams of Ammonium bromide, NH4Br, in enough water to produce 132 mL of solution?
What mass of HCl is contained in 30.0ml of a solution solution which is 37.2 mass% HCl has a density of 1.19g/ml.
KEtones also undergo the aldo condensation, although a succesful reaction often requires "enhanced" conditions, since the addition involves an unfavorable equilibrium constant.
A 309 mL sample of unknown HCl solution reacts completely with Na_2CO_3 to form 10.1 g CO_2. What was the concentration of the HCl solution?
