Answer:
When the volume will be reduced to 2.50 L, the temperature will be reduced to a temperature of 230.9K
Explanation:
Step 1: Data given
A sample of sulfur hexafluoride gas occupies a volume of 5.10 L
Temperature = 198 °C = 471 K
The volume will be reduced to 2.50 L
Step 2 Calculate the new temperature via Charles' law
V1/T2 = V2/T2
⇒with V1 = the initial volume of sulfur hexafluoride gas = 5.10 L
⇒with T1 = the initial temperature of sulfur hexafluoride gas = 471 K
⇒with V2 = the reduced volume of the gas = 2.50 L
⇒with T2 = the new temperature = TO BE DETERMINED
5.10 L / 471 K = 2.50 L / T2
T2 = 2.50 L / (5.10 L / 471 K)
T2 = 230.9 K = -42.1
When the volume will be reduced to 2.50 L, the temperature will be reduced to a temperature of 230.9K

wait a min you dont know the rock cycle?
Explanation:
Answer 1) Option D) 3 moles.
Explanation : In the reaction we can see that the number of moles of hydrogen are equal to the number of water molecules formed. Also, oxygen is found t o be the limiting reactant as equal number of moles are not produced in the reaction.
Here when we use 3 moles of hydrogen then 3 moles of water will be produced. As we are ignoring the moles of oxygen here as that is a limiting reactant.
Answer 2) Option A) 9 moles of reactants chemically change in to 11 moles of product.
Explanation : We can see that 1 mole of pentane reacts with 8 moles of oxygen to produce 5 moles of carbon dioxide and 6 moles of water. So when we add the reactants side we get 1 + 8 = 9 moles and in products it has 5 + 6 = 11 moles.
Hence, 9 moles of reactants produce 11 moles of products.
Answer 3) Option A) 0.62 moles.
Explanation : Here, the number of moles of Cu reacts with 2 moles of silver nitrate and gives 1 mole of copper nitrate and 2 moles of silver.
So, the ratio is 1 : 2 in the reactants side, Now, when we have 1.23 moles of silver nitrate then to calculate the number of Cu.
we can simply cross multiply and get the answer as 1.23 / 2 = 0.615 = ~ 0.62 moles.
