The correct answer is 0.04287 M
It is given that the rate constant of the reaction is 6.2 × 10⁻⁵ mol/L/s
Thus, as the rate of the reaction is in mol/L/s, it is a zero order reaction.
The initial concentration of a is 0.0500 M, and there is a need to find the concentration of a after 115 seconds. This can be done with the help of the equation:
[A]o -[A] = kt
[A] = [A]o - kt
= (0.0500 M) - (6.2 × 10⁻⁵) (115 s)
= 0.04287 M
Answer:
D. 3220
Explanation:
1 km equals 1000 m, so 3.22 km is
3220 m
Answer:
14
Explanation:
The sum of pH and pOH is always equal to 14.
Key to understanding scuba diving is the concept of pressure, and how it varies with depth. We intuitively understand that pressure is some type of force, but how is it actually defined? Pressure is a force or weight<span> per unit area. All matter, </span>including air<span>, has weight due to earth's gravity. Accordingly, anything exposed to air is under pressure - the weight of the atmosphere above it. This weight of air, due to gravity, is known as </span>atmospheric pressure<span> </span>
