Answer:
You have a chemical reaction that is occurring
Answer:
4.0625
Explanation:
1 grams Oxygen to mol = 0.0625 mol
0.0625 x 65 =4.0625
Answer: Option B and E
Explanation: No of neutrons (n) = Mass number - Atomic number= A-Z
A. n=1-1=0
B. n=2-1=1
C. n= 3-1=2
D. n= 2-2=0
E. n=3-2=1
F. n=4-2=2
Hence options B and E are correct
We need to set up an I.C.E chart as follows:
CO H20 CO2 H2
<span>I 0.35 0.40 0 0 </span>
<span>C .35-x 0.40-x x x </span>
<span>E 0.19 0.40-x x x
</span>
We have 0.35 mol of CO at the start and 0.19 remaining. This means that x=0.35-0.19 >> 0.16
<span>Now substitute in 0.16 in your Ke equation. </span>
<span>Just in case you're having trouble with that: </span>
<span>Kb= [Products]/[Reactants] = ([CO][H2O])/([CO2][H2])
</span>
Therefore, the constant of equilibrium would be equal to 0.56.
The chemical equation for this reaction is this:
CO2 + 4H2 = CH4 + 2H2O
from the equation, the mole ration of CO2 to CH4 is ratio 1:1
and CH4 = 25.1
The mole ratio of H2 to H2O is 4:2
therefore, mole of H2 = 19.1* 4/2 = 38.2
The moles of methane produced is 38.2 moles
