An oil refinery or petroleum refinery is an industrial process plant where crude oil is transformed and refined into useful products such as petroleum naphtha, gasoline, diesel fuel, asphalt base, heating oil, kerosene, liquefied petroleum gas, jet fuel and fuel oils.
Thanks Hope it helps.(PLEASE HELP) 500 mL of a gas is collected at 745 mmHg. What will the volume be at 1.8 atm?
Answer:
272.22 mLExplanation:
The new volume can be found by using the formula for Boyle's law which is
[tex]P_1V_1 = P_2V_2[/tex]
where
P1 is the initial pressure
P2 is the final pressure
V1 is the initial volume
V2 is the final volume
Since we're finding the new volume we have
[tex]V_2 = \frac{P_1V_1}{P_2} \\[/tex]
First convert 745 mmHg to atm
760 mmHg = 1 atm
745 mmHg = 745/760 = 0.98 atm
We have
[tex]V_2 = \frac{500 \times 0.98}{1.8} \\ = 272.222...[/tex]
We have the final answer as
272.22 mLHope this helps you
What happens when a current is applied to two electrodes immersed in pure water?

C. Electrolysis occurs, releasing oxygen and hydrogen gas.
Answer:
b
Explanation:
Gucci ghhvhjhsgjjn hvh
Answer:
B
Explanation:
A cylinder is filled with 10.0 L of gas and a piston is put into it. The initial pressure of the gas is measured to be 273. kPa.
The piston is now pulled up, expanding the gas, until the gas has a final volume of 50.0 L. Calculate the final pressure of the gas. Be sure your answer has the
correct number of significant digits.
P2 = 54.6 kPa
Explanation:
Given:
V1 = 10.0 L. V2 = 50.0 L
P1 = 273 kPa. P2 = ?
We can use Boyle's law to solve this problem.
P1V1 = P2V2
Solving for P2,
P2 = (V1/V2)P1
= (10.0 L/50.0 L)(273 kPa)
= 54.6 kPa

Given the following equation: Na2O + H2O ---> 2 NaOH
How many moles of NaOH are produced from 1.02 moles of Na2O?
Answer:
2.04 moles
Explanation:
Since the ratio of Na2O to NaOH is 1:2, you multiply the number of moles by 2, equaling 2.04 moles.

You will be graded on the following rubric:
luje
Answer:
NH3(aq) and HCl(aq) are the reactants, while NH4Cl(aq) is the product.
Explanation:
The hydrogen atom from the HCl molecule joins the other three in NH3 creating a four hydrogen molecule, NH4Cl.
