Which of the following explains how electricity flows? Protons flow from the positive end of a source towards the negative end.E
zalisa [80]
I know for a fact the answer would (not) be the last option. This would not be a way that electricity would be able to really flow.

Your correct answer would be of when the "e<span>lectrons flow from the negative end of a source towards the positive end."

This would be because when the electrons would be free, they would have enough energy to then move from the negative side of the end, to the positive side.</span>

What mass of carbon dioxide is produced from the complete combustion of 6.00×10−3 g of methane?
Crazy boy [7]

The answer for the following problem is explained below.

  • <u><em>Therefore 16.5 × 10^-3 grams of carbon dioxide is produced from the complete combustion.</em></u>

Explanation:

Given:

mass of methane = 6.00 × 10^-3 grams

CH_{4} + O_{2} → CO_{2} + H_{2}O

Firstly balance the following equation:

Before balancing the equation:

CH_{4} + O_{2} → CO_{2}  + H_{2} O

After balancing the equation:

CH_{4}  + 2O_{2} → CO_{2} + 2 H_{2} O

where;

CH_{4}  represents methane molecule

O_{2} represents oxygen molecule

CO_{2}  represents carbon dioxide molecule

H_{2}O  represents water molecule

 

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

        16  grams of methane       →        44 grams of carbon dioxide

        6 × 10^-3 grams of methane →          ?

                 = \frac{44*6.00*10^{-3} }{16}

          = 16.5 × 10^-3 grams of carbon dioxide is produced from the complete combustion.

<u><em>Therefore 16.5 × 10^-3 grams of carbon dioxide is produced from the complete combustion.</em></u>
