Answer:
2994 kJ
Explanation:
When one mol of ethane (C₂H₆) is combusted, 1451 kJ of heat is exchanged.
First we convert 61.9 g of C₂H₆ into moles, using its molar mass:
- 61.9 g ÷ 30 g/mol = 2.06 mol C₂H₆
Finally we <u>calculate how much heat is exchanged by the combustion of 2.06 moles of C₂H₆</u>:
- 2.06 mol * 1451 kJ/mol = 2994 kJ
1. Answer:
B) An allele is one form of a gene.
Explanation:
- <em><u>An allele refers to an alternative form of a gene. In other words it is one of the form of a gene.</u></em>
- <em><u>A gene may have two alleles, where one of the allele is a dominant allele and the other is a recessive allele. </u></em>
- A homozygous organisms may be dominant or recessive, a homozygous recessive contains two recessive alleles while a homozygous dominant contains two dominant alleles.
- A heterozygous organisms contain one dominant allele and one recessive allele.
2. Answer;
B) Alleles
Explanation;
- <em><u>According to Mendel genes are inherited in pairs of alleles that behave in a dominant and recessive pattern. </u></em>
- <em><u>Alleles are alternative forms of a gene. </u></em>
- A gene may have two alleles, where one of the allele is a dominant allele and the other is a recessive allele.
- A homozygous organisms may be dominant or recessive, a homozygous recessive contains two recessive alleles while a homozygous dominant contains two dominant alleles.
The answer is B. The complete equation is C6H12O6 + 6O2 -->6H2O + 6CO2 + energy. So we can know that A and C and D is right. For B, the reaction release energy so it is exothermic reaction.
