a nucleic acid
Explanation: The nucleic acids, both DNA and RNA, consist of polymers ofnucleotides. The nucleotides are linked covalently between the 3' carbon atom of the pentose and thephosphate group attached to the 5' carbon of the adjacent pentose

<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
You rearrange the ideal gas law equation to solve for the pressure by just plugging in the given values.
Did you ever get the awnser to this question cause im stuck on it too
Answer:
validity is the extent to which a test measures what it claims to measure. It is vital for a test to be valid in order for the results to be accurately applied and interpreted.
Explanation:
Validity is important because it can help determine what types of tests to use, and help to make sure researchers are using methods that are not only ethical, and cost-effective, but also a method that truly measures the idea or constructs in question.
