if measurements of a gas are 75l and 300 kilopascals and then the gas is measured a second Time and found to be 50L describe what had to happen to the pressure

Answers

Answer 1
Answer: In this problem, the ideal gas equation PV=nRT is applied. In this relationship, volume is inversely proportional to pressure. Hence, pressure increases when volume decreases, vice versa. In this case, volume is decreased from 75 to 50 L, so the pressure is expected to increase above 300 kilopascals.

How many moles of O2 would be consumed if 13.673 g of V were consumed according to the reaction below?

Answers

To determine how many moles of O2 would be consumed if 13.673 grams of V (vanadium) were consumed in a chemical reaction, you'll first need to know the balanced chemical equation for the reaction. I'll assume the reaction is as follows:

V + O2 → VO2

From the balanced equation, you can see that 1 mole of V reacts with 1 mole of O2 to form 1 mole of VO2. This means that the mole ratio of V to O2 is 1:1.

Now, calculate the number of moles of V in 13.673 grams:

Moles of V = Mass (grams) / Molar mass (g/mol)

The molar mass of V is the atomic mass of vanadium, which is approximately 50.94 g/mol.

Moles of V = 13.673 g / 50.94 g/mol ≈ 0.2684 moles

Since the mole ratio of V to O2 is 1:1, the number of moles of O2 consumed will also be approximately 0.2684 moles.

So, 0.2684 moles of O2 would be consumed if 13.673 grams of V were consumed in the reaction.

What determines when a system reaches equilibrium? What observations can be made about a system once equilibrium has been established?

Answers

Equilibrium is achieved when the reaction rate of the forward and backward reaction are equal or the concentrations of the reactants and the products are in an unchanging ratio. Specifically, this system is in a dynamic equilibrium.
