Maria found an unknown chemical in her cleaning cabinet. She knows that the chemical is either HCl or Mg(OH)2. She decides to test the chemical to help her classify the chemical. The pH measured 11 and the chemical did not affect a piece of blue litmus paper. Is the chemical HCl or Mg(OH)2? * 2 points
The chemical is an acid and must be Mg(OH)2.
The chemical is a base and must be HCl.
The chemical is an acid and must be HCl.
The chemical is a base and must be Mg(OH)2.

Use henry's law and the solubilities given below to calculate the total volume of nitrogen and oxygen gas that should bubble out of 1.7 l of water upon warming from 25 ˚c to 50 ˚c. assume that the water is initially saturated with nitrogen and oxygen gas at 25 ˚c and a total pressure of 1.0 atm. assume that the gas bubbles out at a temperature of 50 ˚c. the solubility of oxygen gas at 50 ˚c is 27.8 mg/l at an oxygen pressure of 1.00 atm. the solubility of nitrogen gas at 50 ˚c is 14.6 mg/l at a nitrogen pressure of 1.00 atm. assume that the air above the water contains an oxygen partial pressure of 0.21 atm and a nitrogen partial pressure of 0.78 atm.
