Answer: To calculate for the enthalpy of formation, it is the sum of all values of products - sum of all values of reactants.
Explanation:
I’m not sure what chemical reaction you are referencing to, but I attached an image below to help you see what I’m saying.
Answer:
The breaking of nuclear bonds
Explanation:
The energy that comes from the breaking of nuclear bonds is what is called nuclear energy
<u>Answer</u><u>:</u>
Hydrocarbon and oxygen
<u>Explanation</u><u>:</u>
"a substance reacts with oxygen gas, it must involve O² as one of the reactants."
Using this, we can confirm Hydrocarbon and oxygen is a valid one.
Answer:
50 mol CH₄
Explanation:
The question is incomplete so I looked it up online.
<em>How many moles CH₄, are needed to produce 50 moles of CO₂?</em>
Step 1: Write the balanced equation for the complete combustion of methane
CH₄ + 2 O₂ ⇒ CO₂ + 2 H₂O
Step 2: Establish the appropriate molar ratio
According to the balanced equation, the molar ratio of CH₄ to CO₂ is 1:1.
Step 3: Calculate the number of moles of CH₄ needed to produce 50 moles of CO₂
We will use the previously established molar ratio.
50 mol CO₂ × 1 mol CH₄/1 mol CO₂ = 50 mol CH₄
