Answer:
300 K
General Formulas and Concepts:
<u>Atomic Structure</u>
<u>Gas Laws</u>
Ideal Gas Law: PV = nRT
- <em>P</em> is pressure
- <em>V</em> is volume
- <em>n</em> is moles
- <em>R</em> is gas constant
- <em>T</em> is temperature
Explanation:
<u>Step 1: Define</u>
<em>Identify variables</em>
[Given] <em>n</em> = 0.5 mol N₂
[Given] <em>V</em> = 6 L
[Given] <em>P</em> = 2 atm
[Given] <em>R</em> = 0.0821 L · atm · mol⁻¹ · K⁻¹
[Solve] <em>T</em>
<em />
<u>Step 2: Solve for </u><em><u>T</u></em>
- Substitute in variables [Ideal Gas Law]: (2 atm)(6 L) = (0.5 mol)(0.0821 L · atm · mol⁻¹ · K⁻¹)T
- Multiply [Cancel out units]: 12 atm · L = (0.04105 L · atm · K⁻¹)T
- Isolate <em>T</em> [Cancel out units]: 292.326 K = T
- Rewrite: T = 292.326 K
<u>Step 3: Check</u>
<em>Follow sig fig rules and round. We are given 1 sig fig as our lowest.</em>
292.326 K ≈ 300 K
A. The air pressure gets higher because there is less air above you.
Answer:
See below
Explanation:
PV = n RT R = .082057 L - Atm / (K-Mole)
.97 V = .118 (.082057)(305)
V = 3.04 liters
Will not change for argon.....will be the same for all ideal gases
Answer:
C. A physical change.
Explanation:
A liquid is cooled during an investigation causing it solidify.Which of the following most likely occurred?
A. Absorption of heat. NO. Heat was released.
B. A chemical change. NO. It was a physical change
C. A physical change. YES. The physical change is called solidification.
D. Formation of a new compound. NO. This would be a chemical change.
Answer:
the answer is 0.041756547635452 we assume you are coverting between moles LiOH and gram
Explanation:
you can view details on each measurements units:monecular weight of LiOH or grams this compound is also known as lithium hydroxide the si base unit for amount of substance is the moles1 moles qual1 moles LiOH..... Sana makatulong sayo lods ang answer ko
