Answer:
0.00915 M of
remain after 5.16 seconds.
Explanation:
Using integrated rate law for first order kinetics as:
Where,
is the concentration at time t
is the initial concentration
Given that:
The rate constant, k =
s⁻¹
Initial concentration
= 0.054 M
Final concentration
= ? M
Time = 5.16 s
Applying in the above equation, we get that:-
<u>0.00915 M of
remain after 5.16 seconds.</u>

Explanation:
A toxic substance is a substance that can cause some harmful effects when a person is exposed to it. The sum of all adverse effects is called the toxicity of a substance. As higher is the toxicity, as dangerous is the substance. The effects can be observed in the mouth, the eyes, the skin, the tract respiratory, the brain, etc.
A substance or agent that can interfere with normal embryonic development is called teratogenic.
A substance or agent capable of causing or producing cancer in mammals is called carcinogenic.
The dose found to be lethal in 50 percent of a group of test animals when administered by the specified route is called LD50 (Lethal Dose 50).
