Answer:
0.045 M/s
Explanation:
Given:
Initial concentration of A = 0.625 M
Final concentration of A = 0.100 M
Total time taken for the change of concentration = 11.6 seconds
The average rate of reaction is calculated as:
= 
on substituting the respective values, we get
= 
or
The average rate of reaction = 0.045 M/s
Answer:
1. The organism becomes ill or may die.
2. Pathogens.
Explanation:
(1) When an organism fails to maintain homeostasis, the organism typically becomes ill, and they will die if homeostasis cannot be re-achieved.

Answer:
a) 6.02 × 10^23
b)6.02×10^23
c)3.01×10^24
d) 3.612×10^24
In every mole of a substance there are 6.02×10^23 entities.
in ( c) there are 5 carbon atoms . 5 is multiplied by the number of moles of the molecule and then multiplied by 6.02×10^23. ( using the formula N=nL )
D is the answer I believe.
