Answer:
D
Explanation:
The sample must contain impurity that is lower in atomic mass to sodium and since potassium has higher atomic mass to sodium, the answer is the sample contains NaCl and LiCl. We are sure already that the sample is not pure which rules out option a and option b contains sodium iodide which cannot contribute to the increase in chlorine
Answer:
Explanation:
Equation of the reaction:
O3(g) + NO(g) ⟶ O2(g) + NO2(g)
From the Rate Law:
R = k[O3][NO]
The order of NO is 1 and that of O3 is also 1, therefore order of reaction = 1 + 1
= 2
Given :
Concentration of O3, [O3] = 7.0×10^-4M
Concentration of NO, [NO] = 5.0×10^-5M
Rate constant, k = 3.0 × 10^6M^-1s^-1
R = 3.0×10^6 × 7.0×10^-4 × 5.0×10^-5
= 0.105 M/s

Answer:
Computer hard drives use magnetism to store the data on a rotating disk. More complex applications include: televisions, radios, microwave ovens, telephone systems, and computers. An industrial application of magnetic force is an electromagnetic crane that is used for lifting metal objects.
