If 2.0 g of gas at 4.0 atm of pressure dissolves in 1.0 L of water at 25 deg C, how much will dissolve in 1.0 L of water at 1.0 atm of pressure and the same temperature?

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! )

Is 343 in the sequence -5, -2, 1, 4, 7

Consider the reaction: 2al(s) + fe2o3(s) → al2o3(s) + 2fe(s) the δhf for fe2o3(s) = -824.3 kj/mole. the δhf for al2o3(s) = -1675.7 kj/mole. finish the equation. δhrxn = [(1)( kj/mole) + (2)( kj/mole)] - [(1)( kj/mole) + (2) ( kj/mole)]
