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>
Answer:
bond angles of 120 degrees.
#1 is 6
#2 During chemistry lab, Mrs. Black’s students placed an antacid tablet in a zip lock bag. They recorded the mass of the tablet in the bag. Then they carefully added 50 grams of water and quickly sealed the bag. The tablet began to fizz and soon disappeared. The bag was filled with gas and it felt cold to the touch.
