Answer: D (The abundance percentage of each isotope)
Explanation: hope this helps!
A + BC ---> AB + C
So here one reactant (A) is accepting a group which is being given by another compound (BC) however the A is not giving any group / element or ion
So this single displacement
Similarly in the given reaction
the anion OH- is only being replaced
The element Ca accepts OH- and H2O loses the same group to form new element H2
So the correct answer is
Single replacement also known as single displacement.
Answer:
C. Egg
Explanation:
has more higher concentration on water.
Answer : The reaction rate at 
are 
Solution : Given,
Mass of tablet = 1000 mg
Volume of water = 0.200 L
Formula used :
Now we have to calculate the reaction rate at different temperatures and reaction time.
Therefore, the reaction rate at are
