Answer: C2H4 + 3O2 → 2CO2 + 2H2O
Explanation:
2Al + 2O2 → 2AlO + O2 Not Balanced Properly: 2Al + O2 = 2AlO
C2H4 + 3O2 → 2CO2 + 2H2O Looks Good
2CH4 + O2 → 2CO + 4H2 Not Correct: CO should be CO2
Ca + O2 → CaOH Not Balanced and No source for the H
Answer:
<h2>7.54 atm </h2>
Explanation:
The required pressure can be found by using the formula for Boyle's law which is

where
P1 is the initial pressure
P2 is the final pressure
V1 is the initial volume
V2 is the final volume
From the question we have

We have the final answer as
<h3>7.54 atm </h3>
Hope this helps you
Answer:

Explanation:
Hello,
In this case, we can study the ideal gas equation that relates temperature, volume, pressure and moles as shown below:

Thus, since we are asked to compute the pressure y simply solve for it as follows:

Best regards.
Answer:
Dilution is the process of decreasing the concentration of a solute in a solution, usually simply by mixing with more solvent like adding more water to the solution
Answer:
B. The reactants will react to produce more H₂O
Explanation:
Given the reaction
2H₂+O₂→2H₂O
A decrease in the amount of H₂O will cause the reaction to produce more H₂O. When you change something, the reaction seeks to undo that change.
