A sample of helium gas occupies 12.4 L at 23oC and 0.956 atm. What volume will it occupy at 40oC and 0.956 atm?

How many liters of ethylene glycol antifreeze (c2h6o2), with a density of 1.100 g/l, would you add to your car radiator containing 15.0 kg of water if you needed to protect your engine to - 21.5°c? for water, kf = 1.86°c m -1.

Na chemical reaction, activation energy increases the of the reactants. this outcome causes the particles to collide, which results in the of new products.

Consider this reaction taking place in a closed 2 liter container: 2so2(g) + o2(g) → 2so3(g) if the volume of the container is decreased to 1 liter, what will happen to the equilibrium of the reaction? it will shift left. it will shift right. it will remain constant it will decrease by half
