Answer:
The ratio 35Cl/37Cl = 3/1
Explanation:
<u>Step 1:</u> Data given
Chlorine has 2 isotopes:
- mass = 35 g/mol
- mass = 37 g/mol
Average molar mass of chlorine = 35.5 grams
<u>Step 2: </u>Calculate the % of isotopes
35x + 37y = 35.5
x+y = 1 or x = 1-y
35(1-y) + 37y = 35.5
35-35y +37y = 35.5
0.5 = 2y
y = 0.25 = 37Cl
x = 1 - 0.25 = 0.75 = 35Cl
<u>Step 3: </u>
The ratio 35Cl/37Cl = 0.75/0.25 = 3/1
Answer:
When iron sulfide is exposed to oxygen it reacts rapidly, releasing large amounts of heat.
Explanation:
i took this from my notes- so whatever aligns with that. sorry if this didnt help but i think its genuinely c heating
Answer:
Explanation:
MM: 30.01
N₂ + O₂ ⟶ 2NO; ΔH = +43 kcal/mol
m/g: 147
Treat the heat as if it were a reactant in the reaction. Then you can write
N₂ + O₂ + 43 kcal ⟶ 2NO
The conversion factor is then 43 kcal/2 mol NO.
1. Moles of NO
2. Amount of heat
As the pressure on the on a gas cofined above a liquid increases, the solubility of the gas will increase
this also happen when we lower the temperature
