Question

If 40
grams of methane (CH4) is buant then how much amount
of cos is liberaled?​

Answer 2

Answer:

100gm

Explanation:

Your reaction will produce 100 g of carbon dioxide.

Start by writing the balanced chemical equation for the combusiont of methane

CH4(g)+2O2(g)→CO2(g)+2H2O(l)

Notice that you have a 1:1 mole ratio between methane and carbon dioxide. This means that the number of moles of carbon dioxide produced will be equal to the number of moles of methane that reacted.

To determine how many moles of methane react, use the compound's molar mass

40g⋅1 mole CH416.04g=2.49 moles CH4

The reaction will thus produce

2.49molesCH4⋅1 mole CO21moleCH4=2.49 moles CO2

To get the mass of carbon dioxide that would contain this many moles, use the compound's molar mass

2.49moles⋅44.01 g1mole=109.6 g CO2

Rounded to one sig fig, the number of sig figs you gave for the mass of methane, the naswer will be

mCO2=100 g CO2
