<span>If you overshoot the endpoint of the acetic acid/NaOH titration, the expected effect on the calculated concentration of acetic acid will be higher because the volume measured for the titrant NaOH which is assumed to react with the acetic acid is more than what is needed to completely react with the given solution.</span>
Answer:
rate = [NO]²[O2]
Explanation:
The rate law for the reaction:
2 NO(g) + O2(g) → 2 NO2(g)
Is expressed in terms of reactants as follows:
rate = [NO]ⁿ[O2]ˣ
<em>Where n and x are the coefficients of the rate law.</em>
<em />
If [NO] is doubled, the rate increased 4 times. That is only possible if:
rate = [NO]²[O2]ˣ
Now, as [NO] is doubled and increased the rate 4 times, and [NO] + [O2] when doubled increased the rate 8 times, doubled [O2] implies increased the rate 2 times. That is only possible is:
<h3>rate = [NO]²[O2]</h3>

Answer:
- The metal industry uses large quantities of copper sulphate as an electrolyte in copper refining, for copper coating steel wire prior to wire drawing and in various copper plating processes
.
- The mining industry employs it as an activator in the concentration by froth flotation of lead, zinc, cobalt and gold ores
.
- The paint industry uses it in anti-fouling paints and it plays a part in the colouring of glass.
Explanation:
Hello,
In this case, since copper sulphate also known as blue stone, blue vitriol is more commonly found in a pentahydrated cupric sulphate due to its stability. In fact it is often the starting raw material for the production of other varied copper-based salts. Henceforth, you will find three applications.
