Obtain from your classmates, the molar enthalpies of neutralization of hydrochloric acid, sulfuric acid, and phosphoric acid when each reacts with sodium hydroxide. Write a chemical equation for each of these neutralization reaction.
How much energy (in J) is required to change the temperature of 1.00 kg Fe from 25.0°C to 1515°C? The specific heat capacity of iron is 0.449 J/g*°C.
Actually, whether these collisions are elastic or inelastic makes no difference as long as the walls are at the same temperature as the gas. Explain.
Sodium peroxide used to remove carbon dioxide from the air supply in space crafts. it works by reacting with the co2 in the air to produce sodium carbonate and O2.
what will the concentration be after 3.00 minutes? B)A zero-order reaction has a constant rate of 3.40×10^?4 M/s . If after 80.0 seconds the concentration has dropped to 3.00×10^?2 M , what was the initial concentration?
