Answer:
The rate of reaction depends on the rate determining step of a nonelementary reaction
Explanation:
A non elementary reaction is a reaction that proceeds in a sequence of steps. One of the steps is usually the slowest step in the reaction sequence. This slowest step is called the rate determining step. In an SN1 reaction, the rate determining step is the formation of the carbocation, the concentration of the carbocation affects the rate of reaction because it is involved in the rate determining step. The attack of the nucleophile is a fast step and does not affect the rate of reaction.
Answer:
70 decibels and above can cause damage if heard for a long time
120 decibels and above is considered an immediate threat
Explanation:
Answer:
1/4
Explanation:
Cystic fibrosis is a recessive disorder and therefore, is expressed only in homozygous recessive genotype. Let's assume that the allele "c" is responsible for the disease in the homozygous state. Since the couple already has a child with cystic fibrosis (cc), they both are heterozygous carriers for the disease.
The genotype of male and female each is "Cc". A cross between Cc x Cc gives progeny in the following phenotype ratio=1/4 diseased: 1/2 normal carriers: 1/4 normal. Therefore, the probability of getting a diseased child for them is 1/4.
It is important to use relatively thick gloves and change them often. If your agency provides you with thin gloves you should double-glove for adequate protection. In my next post I will discuss the second reason for wearing gloves in the crime scene—to protect the evidence from us.28/01/2016
