How do forces in nuclear and chemical reactions differ

2 answers:

8 0

1) Nuclear reactions involve a change in an atom's nucleus, usually producing a different element. Chemical reactions, on the other hand, involve only a rearrangement of electrons and do not involve changes in the nuclei. ... (3) Rates of chemical reactions are influenced by temperature and catalysts.

Answer:

Your pulse will go higher or lower, This explains the changes in our pulse rate because, our heart is having to work twice as hard. Our heart is having to work twice as hard because while its producing oxygen its also getting rid of the Carbon Dioxide. while you are jogging or doing any physical activity than your body requires alot of energy and produce a lot of carbon dioxide which causes the heart to beat fast as to remove co2 and take o2 from the blood leading to higher rate of pulse. on the secon hand if you are sedentary , consumption and production of o2 and co2 respectively will decrease leading to the slow beating of heart leading to low pulse

How many asymmetric centers are present in the open chain form of the aldohexose D-(-)-gulose?

bulgar [2K]

Answer:

D) 4

Explanation:

If we want to find the asymmetric centers, we must first remember that in an asymmetric center, in the carbon, we will have 4 different types of groups bonded to it.

Therefore we must look for carbons that have 4 different groups. With this in mind, we can look at each carbon.

Carbon 1

In this carbon, we have two bonds with the oxygen, therefore, we dont have 4 different groups. So, this is not an asymmetric center.

Carbon 2

In this carbon, we have an "OH" in the top, an hydrogen in the bottom a carbonyl group in the right, and a CHOH in the left. We have 4 different groups. So, this is an asymmetric center.

Carbon 3

In this carbon, we have an "OH" at the bottom, an hydrogen in the top, a CHOH group in the right (that is bonded to a carbonyl group), and a CHOH in the left. We have 4 different groups. So, this is an asymmetric center.

Carbon 4

In this carbon, we have an "OH" at the top, an hydrogen in the bottom a CHOH group in the right (that is bonded to a CHOH group), and a CHOH in the left. We have 4 different groups. So, this is an asymmetric center.

Carbon 5

In this carbon, we have an "OH" at the bottom, an hydrogen in the top, a CHOH group in the right (that is bonded to a CHOH), and a CH2OH in the left. We have 4 different groups. So, this is an asymmetric center.

Carbon 6

In this carbon, we have two bonds with hydrogens, therefore, we dont have 4 different groups. So, this is not an asymmetric center.

See figure 1

I hope it helps!
