Answer:
A. m and n are independent from the molar coefficients of the reactants in the balanced chemical equation.
B. m and n must be determined by experiment.
Explanation:
rate = k[H2O2]^m × [I-]^n
The Order of Reaction refers to the power dependence of the rate on the concentration of each reactant.
Either the differential rate law or the integrated rate law can be used to determine the reaction order of reactants from experimental data.
The results of this experiment gave Rutherford the means to arrive at two conclusions: one<span>, an atom was much more than just empty space and scattered electrons and </span>two<span>, an atom must have a positively charged center that contains most of its mass (which Rutherford termed as the </span>nucleus<span>).

1) Chemical reaction: HI(aq) → H⁺(aq) + I⁻(aq).
It gives an iodide anion.
2) Chemical reaction: H₂O → H⁺(aq) + OH⁻(aq).
It gives a hydroxide anion.
3) Chemical reaction: NH₄⁺(aq) → H⁺(aq) + NH₃(aq).
It gives ammonia.
4) Chemical reaction: HNO₃(aq) → H⁺(aq) + NO₃⁻(aq).
It gives nitrate anion.
Answer:
55.3 M
Explanation:
Given temperature = 25°C
Density = 0.997 g/mL
Based on density the mass of water per L = 997 grams
The molar mass of water = 18
The moles of water =
The molarity is defined as the moles of water per litre.
The moles = 55.3
Volume = 1 L
So molarity = 55.3 /1 = 55.3 M
