<span>The combined Boyle's and Charles' gas law says P1V1/T1 = P2V2/T2 </span>
<span>In this case we have (2.5 atm) (900 ml) / 298 K = (P2) (450 ml) / 336 K -----> </span>
<span>7.55 = 1.34P2 -----> P2 = 7.55 / 1.34 = 5.63 atm</span>
1. 18 L
2. 20.832 L
<h3>Further explanation</h3>
Given
Combustion of ethane
Required
Volume of CO₂
Solution
Avogadro's Law :
In the same T,P and V, the gas contains the same number of molecules
So the ratio of gas volume will be equal to the ratio of gas moles
V₁/n₁=V₂/n₂
1. From equation, mol ratio of C₂H₆ : CO₂ ⇒ 2 : 6
so the volume of CO₂ :
= 6/2 x 6 L
= 18 L
2. mol ethane (MW=32 g/mol) :
= mass : MW
= 10 g : 32 g/mol
= 0.31
mol CO₂ :
= 6/2 x 0.31
= 0.93
The volume CO₂(assume at STP) = 20.832 L
Answer:
true
Explanation:
This sounds like the way an endothermic reaction is going to operate.
It's a very good description of taking on heat which is endothermic.
The statement is true.
Four conditions are needed for a natural selection they are reproduction, hereditary, variation in fitness or organisms, and variation in individual characters among members of the population.
