Answer:
Therefore (2.30-0.03747)= 2.2625 M of HI remains from an initial concentration of 2.30 M after 4.5 hours.
Step-by-step explanation:
second order reaction: The rate of reaction proportional to the square of the concentration of reactant.
For second order reaction

K is rate constant = 1.6×10⁻³M⁻¹hr⁻¹
a = initial concentration of reactant = 2.30 M
a-x = concentration of reactant after t h
t = time = 4.5 h
Putting the values in the above equation,





Therefore (2.30-0.03747)= 2.2625 M of HI remains from an initial concentration of 2.30 M after 4.5 hours.

the total number of markers in the container in all <span>(this one too because it doesnt say anything about markers, but we dont know if there is markers in this or not.)</span>
the total number of pencils in the container in all
Answer:
<em>46.9%</em>
Step-by-step explanation:
0.23/0.49 * 100% = 46.9%
15x-20<130
15x<130+20
15x<150
X=150/15
x<10
Expression is: 2.2 × 10⁴ / 8.8 × 10⁹
= 1 × 10⁴ / 4 × 10⁹
= 0.25 × 10⁴⁻⁹
= 0.25 × 10⁻⁵
= 2.5 × 10⁻⁶
In short, Your Answer would be: Option D
Hope this helps!
