Question 10 (05.04 MC)
The following reaction shows sodium hydroxide reacting with sulfuric acid.
4NaOH + 2H2SO4 → 2Na2SO4 + 4H20
How many grams of Na2SO4 are produced from 10.0 grams of NaOH?
(Molar mass of Na - 22.989 g/mol, O = 15.999 g/mol, H = 1.008 g/mol, S = 32.065 g/mol) (4 points)

Two metal blocks that have slightly different temperatures are placed next to one another. after five minutes, they both have lower but equal temperatures. according to the law of conservation of energy, what  most likelyhappened? energy was created inside the blocks.energy was destroyed inside the blocks.energy was absorbed into the blocks from outside the system.energy was transferred from the warmer block to the cooler block.
