In an accident, a solution containing 40 moles of nitric acid (HNO3) was spilled. Nineteen moles of Na, Co, was quickly spread on the area and CO2 was released by the reaction. Was sufficient Na2CO3 used to neutralize all of
the acid?
2 HNO3 + Na2CO3 → CO2 + H2O + 2 NaNO3

How does a sample of helium at 15 degree celsius compare to a sample of helium at 215 k? a) the helium at 15 degrees celsius has a higher average kinetic energy that the sample at 215 k. b) the helium at 15 degrees celsius has lower nuclear energy that the sample at 215 k. c) the helium at 15 degrees celsius has slower- moving atoms that the sample at 215 k. d) the helium at 15 degrees celsius has smaller atoms than the sample at 215 k.
