g Gaseous methane will react with gaseous oxygen to produce gaseous carbon dioxide and gaseous water . Suppose 0.96 g of methane
galben [10]

Answer: 2.64 g of carbon dioxide that could be produced by the chemical reaction.

Explanation:

To calculate the moles :

\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}    

\text{Moles of} CH_4=\frac{0.96g}{16g/mol}=0.06moles

\text{Moles of} O_2=\frac{6.37}{32}=0.20moles

CH_4(g)+2O_2(g)\rightarrow CO_2(g)+2H_2O(g)

According to stoichiometry :

1 mole of CH_4 require = 2 moles of O_2

Thus 0.06 moles of CH_4 will require=\frac{2}{1}\times 0.06=0.12moles  of O_2

Thus CH_4 is the limiting reagent as it limits the formation of product and O_2 is the excess reagent.

As 1 moles of CH_4 give = 1 mole of CO_2

Thus 0.06 moles of CH_4 give =\frac{1}{1}\times 0.06=0.06moles  of CO_2

Mass of CO_2=moles\times {\text {Molar mass}}=0.06moles\times 44g/mol=2.64g

Thus 2.64 g of carbon dioxide that could be produced by the chemical reaction.

AnnyKZ [126]

Answer:

V=0.048m^3

Explanation:

Hello,

In this case, since the volume is computed by multiplying the given dimensions as follows:

V=0.2m*0.4m*0.6m

The result is shown in cubic meters since each meter is also added:

V=0.048m^3

Best regards.
