Answer:
Rate = K[NH₄⁺][NO₂⁻]
Explanation:
In kinetics studies of reaction, rate law is a mathematical expression that relates speed of reaction with concentrations of the reactants. For a reaction:
aA + nN → cC + dD
The rate law is expressed in terms of [A] and [B] as follows:
Rate = K[A]ᵃ[N]ⁿ
<em>Where K is rate constant.</em>
<em />
For the reaction:
NH4+ + NO2– ⟶ N2 + 2H2O
The rate law is:
<h3>Rate = K[NH₄⁺][NO₂⁻]</h3><h3 />
<em>As was said in the problem, the rate is porportional to [NH₄⁺] and to [NO₂⁻]</em>

Explanation:
Hello!
In this case, since the molarity of the iodide ion is computed by dividing the moles of iodide ions by the volume of solution in liters (0.150 L), we first need to compute the moles of zinc iodide (ZnI2) by using its molar mass and then using a mole ratio of 1 mol of zinc iodide to 2 mol of iodide ion:
Therefore, the resulting molarity turns out:
Best regards!
The second blank is living. I'm not sure what the first one is.
Answer:
Li to Zn2+
Explanation:
Because oxidation number of Li changes from 0 to 2+ it means that Li has lost two electrons and oxidation number of Zn2+ changes to Zn which means Zn received two electrons.
