Bob needs to mix 2 cups of liquid lemonade concentrate with 3.5 cups of water to make lemonade. bob has 6 cups of lemonade concentrate. how much lemonade can he make?

Iam in desperate need of with this !

In a reaction (at equilibrium) that makes more moles of gas than it consumes, what is the effect of increasing the pressure?

Suppose you mix one mole of sulfuric acid (h2so4) with 1 mole of sodium hydroxide(naoh). why does the ph of the solution remain below 7? ( explain so i can get better understanding! )
