The given question is incomplete. The complete question is :
This is the chemical formula for carvone (the chemical that gives spearmint its flavor)
: An organic chemist has determined by measurements that there are 27.3 moles of carbon in a sample of carvone. How many moles of oxygen are in the sample
Answer: 2.73 moles of oxygen are there in the sample.
Explanation:
The chemical formula of carvone is
.
This means:
When 10 moles of carbon are there in carvone , 1 mole of oxygen is there in carvone
Thus for 27.3 moles of carbon in carvone ,
mole of oxygen is there in carvone.
Thus 2.73 moles of oxygen are there in the sample.
option of d is the write answer
Yes, because cotton is a plant and then the cotton is then made into a ball of yarn.
Hi , basically dominant alleles are always expressed in the organism , while recessive traits tend to be expressed only when the dominant allele is not present.
Answer:
The biological significance is that it is the normal human body temperature and also the optimum temperature of the enzyme.
Explanation:
- Enzymes are biological catalysts that speed up the rate of chemical reactions.
- Enzymes catalyze specific reactions by working on a specific substrate to convert it into a product.
- The rate of enzyme activity depends on several factors which include pH, temperature, substrate concentration, and enzyme concentration among others.
- Enzymes work best at a specific pH and temperature known as optimum pH and optimum temperature respectively.
- In this case, enzyme amylase works best at a temperature of 37° C which is equivalent to the normal human body temperature.
