Solid sodium reacts violently with water, producing heat, hydrogen gas, and sodium hydroxide. how many molecules of hydrogen gas are formed when (46.3 g) 48.7 g of sodium are added to water? show your work. assume the sodium is limiting:
na (s) + h2o (l) h2 (g) + naoh (s)
also if sodium is the limiting reactant, what does this indicate about h2o in this reaction?

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.
