9. Why did you choose the answer above (explain why)? 1pt
Answer:
Its velocity was 7.8 km/s northward.
Explanation:
Because the meteor was only 45 m wide and was 27,700 km above Earth's surface it was not visible with the aid of a telescope.

9. Do all enzymes function at the same pH?
Each enzyme has an optimum pH but it also has a working range of pH values at which it will still work well. This depends on the type of enzyme. The enzyme pepsin breaks down proteins in the acidic conditions of the stomach. ... Catalase has an optimum pH of 9 and a working range of between pH 7-11. Hope this was helpful

Why does lowering the pressure cause a liquid to boil?
A. It becomes easier for molecules to escape.
B. It pushes molecules out of the liquid.
C. It causes the temperature to rise.
D. It changes the volume of the liquid.
Lowering the pressure in a container will cause the liquid in the container to boil faster because it becomes easier for the molecules to escape.
What causes boiling?Boiling happens when the vapor pressure of a liquid equals the atmospheric pressure.
By lowering the atmospheric pressure, the vapor pressure of a liquid takes a lower time to equal the atmospheric pressure.
Thus, it becomes easier for the molecules of the liquid to escape from each other.

An initial mixture of nitrogen gas and hydrogen gas is reacted in a rigid container at a certain temperature as follows:
Answer:
The concentration of nitrogen gas and hydrogen gas that reacted initially are 10.0 M and 11.0 M respectively.
Note: The question is incomplete. The complete question is as follows:
An initial mixture of nitrogen gas and hydrogen gas is reacted in a rigid container at a certain temperature as follows:
3H2(g)+N2(g)⇌2NH3(g)
At equilibrium, the concentrations are
[H2] = 5.0 M, [N2] = 8.0 M, and [NH3] = 4.0 M.
What were the concentrations of nitrogen gas and hydrogen gas that were reacted initially?
Explanation:
Given the following data:
Concentration of H2 at equilibrium = 5.0 M
Concentration of N2 at equilibrium = 8.0 M
Concentration of NH3 at equilibrium = 4.0 M
The given equilibrium reaction is,
Initial a b c
Change -3x -x +2x
Equilibrium (a-3x) (b-x) +2x
The value of x is calculated from the equilibrium of NH3
Concentration of NH3 at equilibrium = 4.0 M = 2x
x = 2.0 M
Substituting the value of x above
Initial Concentration of H2:
a - 3 × 2.0 M = 5.0 M
a = 6.0 M + 5 = 11.0 M
Initial Concentration of N2:
b - 2.0 M = 8 M
b = 8.0 M + 2.0 M
b = 10.0 M
Therefore, the concentration of nitrogen gas and hydrogen gas that reacted initially are 10.0 M and 11.0 M respectively.
