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>

Answer:

I hope this helps you! :)

Explanation:

In peas, yellow pods are dominant to green pods. A homozygous recessive pea plant crosses with a heterozygous pea plant. Use the
Lorico [155]

Answer:

  • <u><em>50% of the offspring will have green pods.</em></u>

Explanation:

Use a upper case to identify the dominant allele and lower case to identify recessive allele.

<em>A homozygous pea plant</em> would be YY or gg. The <em>homozygous recessive pea pleant</em> would be gg (YY is dominant).

<em>A heterozygous pea plant</em> would be Yg (or gY which is the same).

The <em>Punnett Square </em>for the cross between a <em>homozygous recessive pea plant</em> (gg) and a <em>heterozygous pea plant</em> (Yg) would be:

                 g        g

       Y      Yg      Yg

       g      gg      gg

Hence, <em>the offspring will have</em> two Yg, which would be yellow pods, and two gg which would be green pods.

That is, 50% of the offspring will have yellow pods and 50% will have green pods.
