Answer:
Option A is correct.
Because two molecules of NO are consumed per molecule of O2, the rate of disappearance of O2(g) is 2.5×10−5 Ms−1.
Explanation:
2NO(g) + O2(g) → 2NO2(g)
The rate of a chemical reaction is defined as the amount of reactant used up or the amount of products formed in the reaction.
From the chemical balance, 2 moles of NO gives 1 mole of O2, hence, it is evident that 2 molecules of NO is consumed per 1 molecule of O2.
Hence, the rate of consumption of O2 is exactly half of the rate of consumption of NO.
Rate of consumption of O2 = (1/2) × Rate of consumption of NO = (1/2) × 5.0×10−5 Ms−1
= (2.5×10−5) Ms−1

Answer:
1) S2N
2)ClI
Explanation:
A chemical formula shows the relative ratio of atoms present in a compound. When we write a chemical formula, we have an idea of the ratio in which atoms combine in the compound of interest. This is a great clue when we are attempting to elucidate the structure of the compound.
For hexasulphur mononitride,the formula of the compound must be S6N3, this reduced to lowest terms to give S2N.
Similarly, the formula for chlorine monoiodide is ClI as shown in the answer above.
You can use the law of superposition:in horizontal sedimentary rock,the oldest layer is at the bottom.the more layers up is younger than the ones under
C₁ * V₁ = C₂ * V₂
1.0 * 20 = C₂ * 60
20 = C₂ * 60
C₂ = 20 / 60
C₂ = 0.33 M
hope this helps!
