Answer:
2CO + O₂ → 2CO₂ ΔH = -566 kj
Explanation:
Given data:
Energy evolved when 1 mole of CO react = 283 Kj
Energy evolved when 2 mole of CO react = ?
Solution:
Chemical equation:
2CO + O₂ → 2CO₂
It is given when one mole of CO react with oxygen 283 KJ energy is produced.
When 2 mole react,
2 ×-283 kj = -566 kj
Thermal equation:
2CO + O₂ → 2CO₂ ΔH = -566 kj
Answer:
A) $0.208 per unit
B) $0.220 per unit
C) An inspector should be hired
Explanation:
percentage of defect rate = 2% = 0.02
cost of inspector = $10 per hour
production rate = 48 per hour
cost of not hiring an inspector = $11
A) Determine the inspection cost per unit if an inspector is hired
= cost of inspector / production rate
= 10 / 48 = $0.208 per unit
B) Determine the defective cost per unit if an Inspector is not hired
= cost of not hiring an inspector * percentage of defect rate
= 11 * 0.02
= $0.220 per unit
C) Inspection cost < defective cost i.e. $0.208 < $0.220 hence an inspector should be hired
Answer:
Explanation:
To interpret this pedigree, let’s start with information that we already know:
Brown is recessive, which means brown individuals must have the phenotype BB. In this pedigree, brown individuals are filled in.
Black is dominant, which means black individuals must have at least one B allele. Their phenotype could be either BB or BB. In this pedigree, black individuals are not filled in.
Figure 5 shows the same pedigree, but with information about the individual’s phenotype filled in.
The shaded individual, who is a brown female puppy, must have the phenotype BB. If she had any B alleles, she would be black because the black allele is dominant over the brown allele.
In order for the brown puppy to have the phenotype BB, she must have gotten two “b” alleles: one from each of her parents. We know that her parents are both black (because they are unshaped), which means they must have a least one “B” allele. This means that both parents must be heterogeneous: BB.
The three black puppies must have at least one “B” allele in order for them to be black in color. However, we can’t tell whether they are homologous dominant (BB) or heterogeneous (BB) since both of those phenotype would result in black color. One way to represent this on a pedigree is B-, meaning that the second allele could be either B or b.
