Answer:
C5 and its absolute configuration is R
Explanation:
<u>A chiral center is a carbon atom (C) which is bonded to four different groups, generating optical activity in the molecule. </u>
The first two chiral centers are:
- C1: bonded to OH, H, the carbon chain (seen from left to right) and the carbon chain (seen fron rigth to left).
- C2: bonded to CH3, the above C and its CH3, the carbon chain (seen from left to right) and the carbon chain (seen fron rigth to left).
The thrid chiral center is C5, which is bonded to H, the above C and its CH3, the carbon chain (seen from left to right) and the carbon chain (seen fron rigth to left).
The absolute configuration of it is R (clockwise)
Answer:
The concentration of one or more of the products is small.
The reaction will not proceed very far to the right.
The reaction will generally form more reactants than products
Explanation:
We often write
K =[Products]/[Reactants]
Thus, if K is small
- We have fewer products than reactants
- We have more reactants than products
- The position of equilibrium lies to the left
A. is wrong. Usually, if K < 1, the concentration of reactants is greater than that of the products.
to write 0,0045 in scientific notation, we will have to move the decimal point three point to right, which literally means multiplying by 1000=103 . Hence in scientific notation 0.0045=4.5×10−3 (note that as we have moved decimal three point to right we are multiplying by 10−3 this is an example
Answer:
70 180 000 kg
Explanation:
We can solve this problem by multiplying the amount of garbage each Canadian throws out each day (2.2 kg) by the number of Canadians:
- 2.2 kg/person * 31 900 000 persons = 70 180 000
Thus according to this problem, all Canadians throw out 70 180 000 kg of garbage each day.
