Answer:
It becomes shorter
Explanation:
A wave, such as a Soundwave, controls volume based on it's Wavelength. A Louder sound has a shorter wavelength, a softer sound has it's waves spread out more. Amplitude is simply a fancy name for Volume in Amps. When amplitude increases, the volume increases. Thus, waves become shorter.
Answer:
The answers are in the explanation
Explanation:
A. For the reaction:
CO(g) + H₂O(g) ⇌ CO₂(g) + H₂(g); ΔH°=−41kJ.
As the reaction is exothermic ( ΔH°<0), you need to use low temperature to increase the equilibrium yield of hydrogen -LeChatelier's principle-.
We would use <em>low </em>temperature. For an <em>exothermic </em>reaction such as this, <em>decreasing </em>temperature increases the value of K and the amount of products at equilibrium.
B.
c. No. We cannot increase the equilibrium yield of hydrogen by controlling the pressure of this reaction.
It is possible to increase the equilibrium yield of reaction by controlling the amount of reactants added. As reactants and products are gases, the pressure of the reaction will not change the amount of reactants or products in the equilibrium.

The molarity of the resulting solution is 0.65 M.
<h3>Which molarity is it?</h3>
- To be able to comprehend what we mean by the molarity of a solution, we must first go back in time. We are aware that molarity refers to the concentration of the component in the solution. In this situation, it's important to be aware that the molarity can only be represented in terms of moles per litre.
- The number of moles of the gas must now be determined, and this can only be done by applying the ideal gas equation, which is what we will be able to accomplish in this issue.
PV = nRT
Pressure is P.
Volume is V.
The number of moles is n.
Gas constant R
Temperature is T
n = PV/RT
n = 0.97 * 12.7/0.082 * 306
n = 12.3/25.1
N=0.49 moles.
Number of Mole/Volume Equals Molarity of the Solution
0.49 moles/0.750 liters
= 0.65 M

#SPJ4
The amount of substance at a certain time t, At, with half-life of h is determined by the equation,
At = (Ao)(0.5)^(t/h)
where Ao is the original amount.
From the given,
At/Ao = 0.45 = (0.5)^(t/432)
The value of t from the equation is 497.67 years.
42700 milliliters would be the answer...
Hope this helps!
