a). What mass of carbon dioxide is produced from the complete combustion of 2.30×10−3g of methane?

b)What mass of carbon dioxide is produced from the complete combustion of 2.30×10−3 g of methane?

Can someone step me through this?

This is the unbalanced equation given:

CH4+O2->CO2+H2O to go with that problem

balance it.

then look at the mole ratio of methane to CO2.

How many moles of methane do you start with? Using the mole ratio, how many moles of CO2 do you get? How many grams is that?

I balanced the equation and got CH4+2O2->+2H2O

so would the mole ratio of CO2 be 1/2

To find the mass of carbon dioxide produced from the complete combustion of methane, we need to use the balanced chemical equation for the combustion of methane.

The balanced chemical equation for the combustion of methane (CH4) is:

CH4 + 2O2 → CO2 + 2H2O

From the equation, we can see that one molecule of methane reacts with two molecules of oxygen to produce one molecule of carbon dioxide and two molecules of water.

Now, let's calculate the molar mass of methane (CH4) and carbon dioxide (CO2).

The molar mass of carbon is 12.01 g/mol and the molar mass of hydrogen is 1.01 g/mol.

Molar mass of methane (CH4) = (12.01 g/mol x 1 atom of carbon) + (1.01 g/mol x 4 atoms of hydrogen) = 16.04 g/mol

Molar mass of carbon dioxide (CO2) = (12.01 g/mol x 1 atom of carbon) + (16.00 g/mol x 2 atoms of oxygen) = 44.01 g/mol

a) Now, let's calculate the mass of carbon dioxide produced from the combustion of 2.30×10−3 g of methane.

To do this, we need to use the molar mass and stoichiometry of the balanced equation.

First, calculate the number of moles of methane using the equation:

moles of CH4 = mass of CH4 / molar mass of CH4
= 2.30×10−3 g / 16.04 g/mol

Next, use the stoichiometry of the balanced equation to determine the number of moles of carbon dioxide produced.

From the balanced equation, we can see that for every 1 mole of CH4, we get 1 mole of CO2.

Therefore, the moles of CO2 produced = moles of CH4

Finally, calculate the mass of carbon dioxide produced using the equation:

mass of CO2 = moles of CO2 x molar mass of CO2

b) The steps to solve part b are the same as part a. Just replace the mass of methane (CH4) with 2.30×10−3 g and follow the same calculations.

Note: Make sure to use the correct number of significant figures throughout the calculation and round the final answer to the appropriate number of significant figures.
