Answer:
I think it will option B it will retain enough heat
Answer:
CH₄ + 2O₂ –> CO₂ + 2H₂O
The coefficients are: 1, 2, 1, 2
Explanation:
CH₄ + O₂ –> CO₂ + H₂O
The above equation can be balance by as follow:
CH₄ + O₂ –> CO₂ + H₂O
There are 4 atoms of H on the left side and 2 atoms on the right side. It can be balance by writing 2 before H₂O as shown below:
CH₄ + O₂ –> CO₂ + 2H₂O
There are 2 atoms of O on the left side and a total of 4 atoms on the right side. It can be balance by writing 2 before O₂ as shown below:
CH₄ + 2O₂ –> CO₂ + 2H₂O
Now, the equation is balanced.
The coefficients are: 1, 2, 1, 2
One lead atom, two nitrogen atoms, four oxygen atoms.
Answer:
Explanation:
Here's where all that equation balancing is going to come into use. Since the main object of the question is not the equation, I'm just going to balance it and use it.
4Fe + 3O2 ====> 2Fe2O3
Step One
Find the number of mols of O2 in 24.9 grams of O2
1 mol O2 = 2*16 = 32 grams
x mol O2 = 24.9 grams Cross multiply
32x = 24.9 * 1 Divide by 32
x = 24.9/32
x = 0.778 moles of O2
Step Two
Type the findings under the balanced equations parts. Solve for the number of moles of Fe
4Fe + 3O2 ====> 2Fe2O3
x 0.778
Step Three
Set up the proportion
4/x = 3/0.778 Cross multiply
Step Four
Solve the proportion moles of Fe
4*0.778 = 3x
3.112 = 3x Divide by 3
3.112/3 = 3x/3
x = 1.037 moles of Fe
Step Five
Find the mass of Fe
1 mol Fe = 56 grams
1.037 mol Fe = x Cross Multiply
x = 56*1.037
x = 58.1 grams
20000 centimeters because 1 dekameter is 1000 centimeters
