Answer:

The mass of coke needed to react completely with 1.0 ton of copper(II) oxide is 0.794 Ton.

Explanation:

2CuO+C\rightarrow 2Cu+CO_2

1 Ton = 907185 grams

Mass of copper oxide = 1.0 Ton = 907185 grams

Moles of copper oxide =\frac{907185 g}{79.55 g/mol}=11,403.95 moles

According to reaction, 2 moles of copper oxide reacts with 1 mole of carbon.

Then 11403.95 moles of copper oxide will react with:

\frac{1}{2}\times 11403.95 mol=5,701.98 mol of carbon

Mass of 5,701.98 moles of carbon:

5,701.98 mol\times 12 g/mol=68,423.75 g

Mass of coke = x

Mass of carbon = 68,423.75 g

Percentage of carbon in coke = 95%

95\%=\frac{68,423.75 g}{x}\times 100

x=720,250.09 g=0.794 Ton

The mass of coke needed to react completely with 1.0 ton of copper(II) oxide is 0.794 Ton.

dmitriy555 [2]

Dominant allele

Explanation:

An allele whose trait shows up in an organism when the allele is present is called a dominant allele.

An allele whose trait does not show up in an organism when present is called a recessive allele.

  • An allele is the two possible forms of gene.
  • A gene can be dominant or recessive in nature.
  • An allele is a DNA that occupies a particular locus on a chromosome.
  • They usually occur in pairs.
  • The allele determines hereditary characteristics.
