What happens when there is It increases the total number of molecular collisions that
an increase in temperature occur
for a reaction rate?
Select all that apply. It increases the percentage of collisions that result in a reaction
What is latent heat of the amount of heat released when a certain mass of a substance
condensation? changes from a gas to a liquid
The greater the average the higher the temperature
kinetic energy of the
particles in a sample of
matter, __________.
Why do water molecules The exposed charge on hydrogen's protons are attracted to
tend to stick to each other to unshared electron pairs on oxygen atoms.
form a liquid?
0.25
A solution is formed by
dissolving 83.2 grams of
copper II chloride (CuCl22) in
2.5 liters of water. The molar
mass of CuCl22 is 134.45
g/mol. What is the molarity
of the solution?
, A mixture consists of 45% 0.369
oxygen, 12% argon, and 43%
nitrogen by volume. A sample
of this mixture has a pressure
of 2.0 atm in a 5.3 L container
at 350 K temperature. How
many moles of gas are in the
container?
What type of reaction is Exothermic: Energy is released to the environment during the
shown in the graph, and formation of the products.
why?
Examine the image, which D
shows four chemical
systems of colliding
molecules. Which chemical
system has the highest
reaction rate?
Study the following The rate of the forward reaction is at its maximum when the
equation.Fe(s) + 2 HCl(aq) ⇌ reaction first starts.
H22(g) + FeCl22(aq) What
happens to the iron metal The rate of the reverse reaction increases as hydrogen gas
when it is reacted in a closed accumulates.
