Answer:
2.067 x 10⁻⁷ M/min.
Explanation:
- Knowing that the rate of the reaction is the change in the concentration of reactants (decrease) or the products (increase) with time.
- For the reaction: <em>2NOCl ⇄ 2NO + Cl₂,</em>
<em>Rate of the reaction = - 1/2 d[NOCl]/dt = 1/2 d[NO]/dt = d[Cl₂]/dt</em>
∵ d[Cl₂] = 3.39 x 10⁻³ M, dt = 1.64 x 10³ min.
∴ Rate of the reaction = d[Cl₂]/dt = (3.39 x 10⁻³ M) / (1.64 x 10³ min) = 2.067 x 10⁻⁷ M/min.

Hello,
In this case, we use the Avogadro's number to compute the molecules of C2F4 whose molar mass is 100 g/mol contained in a 485-kg sample as shown below:

Decomposers break down dead organic material to water, carbon dioxide, minerals and other simple chemicals which can again be consumed by green plants.
Answer:
its carbon
Explanation:
iron oxide + carbon = iron + carbon dioxide
as coke(mainly carbon) is a raw material gone into a blast furnace displaces iron.
Answer:
Accuracy
Explanation:
Accuracy is the nearness of measurement to true value.
Precision deals with the ability to be able to reproduce a set of result.
In calculating percentage error, we simply find the difference between the approximately measured value and the true value. We then divide by the true value and express as a percentage.
This percentage shows how much error was incurred in our expriment which did not yield the true value. An accurate result has a low percentage error.
