Answer:
<u>d) 1.8 atm</u>
Explanation:
<u>According to Boyle's Law,</u>
Here, we are given :
- <u>P₁ = 1.5 atm</u>
- <u>T₁ = 25°C = 298 K</u>
- <u>T₂ = 75°C = 348 K</u>
<u />
<u>Solving</u>
- P₂ = P₁T₂/T₁
- P₂ = 1.5 x 348 / 298
- P₂ = 522/298
- P₂ = <u>1.8 atm</u> (approximately)
Answer:
When you freeze the already cracked glow stick the chemical reactions are slowed down. When you take it out of the freezer and it reaches room temperature the chemical reaction will go on as 'normal'. XD hope this helps
Explanation:
1) Reaction:
Mg(s) + 2HCl (aq) ----> H2(g) + MgCl2(aq)
2) Analysis
An increase in pressure affects directly the rate of reaction involving reactiong gases. Changing the pressure where there are only solids or liquids does not affect the rate of reaction.
This reaction is not an equilibrium, the reaction is only forward. So, the reacting components, Mg(s) and HCl(aq) are a solid and a liquid.
Therefore, the reaction is not affected by the change in pressure.
Answer: the reaction is not affected at all.
