Answer:
The temperature will increase or doubled.
Explanation:
In Amonton's Law, it states the pressure of a given amount of gas is directly proportional to its temperature on Kelvin scale when the volume is held constant.
1.1 / 2 = .7 --> 2.86 yrs
.7 / 2 = .45 —> 5.72 yrs
.45 / 2 = .225 —> 8.58 yrs
.225 / 2 = .1125 —> 11.44 yrs
So, for the sample of plutonium to reach .140 mg it should take a little less than 11.44 years.
Hope this helps
The answer above is correct (I took a test on this)
Answer:
49.09 moles of gas are added to the container
Explanation:
Step 1: Data given
Initial volume = 3.10 L
Number of moles gas = 9.51 moles
The final volume = 19.1 L
The pressure, temperature remain constant
Step 2: Calculate number of moles gas
V1/n1 = V2/n2
⇒with V1 = the initial volume of the gas = 3.10 L
⇒with n1 = the initial number of moles = 9.51 moles
⇒with V2 = the increased volume = 19.1 L
⇒with n2 = the final number of moles gas
3.10L / 9.51 moles = 19.1 L / n2
n2 = 58.6 moles
The new number of moles is 58.6
Step 3: calculate the number of moles gas added
Δn = 58.6 - 9.51 = 49.09 moles
49.09 moles of gas are added to the container

Let's start by stating what we know is wrong. Equilibrium is achieved when the reactants and products have a stable concentration. That makes D incorrect. Equilibrium is not established until about the 6th or 7th second.
The fact that you get any products at all means that the reactants will become products. Just who is favored has to be looked at very carefully. The products start very near 0. They go up until their concentration at equilibrium. When the reach equilibrium, the products have increased to 17. The reactants have dropped from 40 to 27. By a narrow margin, I would say the products are favored.
C is incorrect. There are still reactants left.
E is incorrect. the reactants started out with a concentration of 40. The reaction is not instantaneous. The concentration was highest at 40 or right at the beginning. This assumes that the reactants were mixed and the products were produced and the water/liquid amount has not changed.
B is incorrect. The concentration of the reactants is higher at equilibrium.
A is wrong. It is product favored.
I'm getting none of the above.
Problem Two
AgBr is insoluble (very). You'd have to work very hard to get them to separate into their elemental form. Just putting AgBr in water isn't enough. Lots of heat and lots of electricity are needed to get the elemental form.
I suppose you should pick B. Mass must be preserved. But if you balanced the equation, it would work with heat and electricity.
