A student carried out this reaction with methane as the limiting reagent. A 12.0 g quantity of methane was used, and the student
Sophie [7]

Answer:

The percent yield is 66.7%

Explanation:

1. The balanced chemical reaction to obtain carbon dioxide from the methane is:

CH_{4}+2O_{2}=CO_{2}+2H_{2}O

2. Calculathe the theoretical quantity of carbon dioxide.

As the problem says that the limiting reagent is the methane, all the calculations will be made from this quantity:

12.0gCH_{4}*\frac{1molCH_{4}}{16gCH_{4}}*\frac{1molCO_{2}}{1molCH_{4}}*\frac{44gCO_{2}}{1molCO_{2}}=33gCO_{2}

3. Calculate the percent yield:

Percent yield = \frac{actualyield}{theoreticalyield}*100

Percent yield = \frac{22.0g}{33.0g}*100

Percent yield = 66.7%

PLEASE HELP ASAPPPP

So what you do is you write out each element separately and how many of that element on either side of the arrow S-8|S-1
O-2|O-2
on one side theres 8 (S) and 2 (O) and 1(S) and 2(O) if you put a number in front to balance it you are multiplying it the elements number like
SO2 if I put a 2 in front now I will have 2(S) and 4(O)
