false is the answer to this question.
1 CH4 (g) + 2 O2 (g) -----> CO2 (g) + 2H2O(l) ΔH= - 890 kJ
1 mol 2 mol
1) If ΔH has minus, it means "release". We need only "release" choices.<span>
2) From reaction
1 mol </span>CH4 (g) "releases" ΔH= - 890 kJ - We do not have this choice.
2 mol O2 (g) "release" ΔH= - 890 kJ, so
1 mol O2 (g) "release" ΔH= - 445 kJ
Correct answer is B.
The 1 one electrons have positive charge
Answer:
1086.2 L
Explanation:
The computation of the volume of the elevation is given below:
Here we assume the volume of the elevation be x
As we know that
V¹ ÷ T¹ = V² ÷ T²
Here
V^1 = 1500
T^1 = 290
V^2 = x
T^2 = 210
Now place these values to the above formula
So,
1500 ÷ 290 = x ÷ 210
x = 1086.2 L
