Answer:
Boyle's law states that the volume of a fixed mass of agass at constant temperature is inversely proportional to its pressure
Answer:
65
Explanation:
Atomic Number, Protons, and Neutrons are always of the same amount.
<span>Carbon monoxide has a special type of bond that is a triple bond. The triple bond consists of two covalent bonds in which the elements share some of the outer electrons and then is a dative covalent bond. This is a bond that gives the elements a special kind of group and power in relation to the strength when attempting to break it up.</span>

<u>Gas Laws</u>
Ideal Gas Law: PV = nRT
- <em>P</em> is pressure
- <em>V</em> is volume
- <em>n</em> is number of 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> = 0.68 mol H
[Given] <em>T</em> = 298 K
[Given] <em>V</em> = 4.5 L
[Given] <em>R</em> = 0.0821 L · atm · mol⁻¹ · K⁻¹
[Solve] <em>P</em>
<em />
<u>Step 2: Find Pressure</u>
- Substitute in variables [Ideal Gas Law]: P(4.5 L) = (0.68 mol)(0.0821 L · atm · mol⁻¹ · K⁻¹)(298 K)
- Multiply [Cancel out units]: P(4.5 L) = (0.055828 L · atm · K⁻¹)(298 K)
- Multiply [Cancel out units]: P(4.5 L) = 16.6367 L · atm
- Isolate <em>P</em> [Cancel out units]: P = 3.69705 atm
<u>Step 3: Check</u>
<em>Follow sig fig rules and round. We are given 2 sig figs as our lowest.</em>
3.69705 atm ≈ 3.7 atm
