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
Hey there!!
since bubble reaction means chemical as you said, then yes its a chemical reactant.
Hope this helped an have a great day
Electrons are emitted from the surface of a metal in photoelectric effect.
<h3>What is the photoelectric effect?</h3>
The photoelectric effect is the emission of electron from the surface of a metal when light is shone on the surface..
For electrons to be emitted, the light must have a certain frequency known as threshhold frequency.
Therefore, electrons are emitted from the surface of a metal in photoelectric effect.

Answer: Oxidation reaction occurs when a reactant losses electrons in the reaction.
Reduction reaction occurs when a reactant gains electrons in the reaction.
Explanation: Reduction reaction : It is defined as the reaction in which a substance gains electrons. That means, the gain of electrons takes place.
Or we can say that, reduction reaction occurs when a reactant gains electrons in the reaction.
Redox reaction or Oxidation-reduction reaction : It is defined as the reaction in which the oxidation and reduction reaction takes place simultaneously.
