Non-metals tend to form negative ions (anions )
Answer: The bacteria uses the oxygen present in the mouth.
Explanation:
The plaque that is formed in the teeth is a highly anaerobic bacteria but it can sustain in the environment rich in oxygen. The oxygen is used by the bacteria and there is a absence of oxygen in the teeth.
It is formed in between the teeth which needs oxygen to survive and if remains for tooth for a longer period of time then it began to grow without oxygen.
It basically uses the oxygen available in the mouth and makes the condition anaerobic.

Answer:
k ≈
Explanation:
For a first order reaction
Half life ( ) = 0.693 / k
k = rate constant
= 26.01
hence k = 0.693 / ( 26.01)
k ≈ 2.7 * 10^-2 d^-1
This is a detailed simple solution as required
