Statement:

The best way to measure the mass of an orange is to use a balance. You put the orange and the mass pieces in the same cup on the balance and find out how many centimeters it is. The mass of my orange was 145.

Explanation:

Problem 1

The student has not done a good job in measuring the weight of the orange. In fact, the has complicated his simple problem.

Reasons:

Using the mass pieces and the cup to find the weight of the orange is wrong approach.

He can easily place the orange on the balance and read off the weight.

Centimeters is a unit of length. What length is he measuring and recording?

The unit of weight is in newtons(N).

Mass is not read from a balance. A balance gives the weight of substance. Mass is different from weight.

Problem 2

Rewriting to paragraph to correct the errors:

The best way to measure the mass of an orange is to use a balance. You put the orange on the balance and find out how many newtons it is. The weight in newtons can be converted to mass in kilogram. The mass of my orange will be 145kg.

Answer:

The forward reaction is occurring at a faster rate than the reverse reaction.

Explanation:

Reaction quotient (Q) of the given reaction is -

$Q=\frac{[NO]^{2}}{[N_{2}][O_{2}]}$

where [NO], $[N_{2}]$ and $[O_{2}]$ represents concentrations of respective species at a certain time.

Here $[N_{2}]$ = 0.80 M, $[O_{2}]$ = 0.050 M and [NO] = 0.10 M

So, $Q=\frac{(0.10)^{2}}{(0.80)\times (0.050)}=2$

Hence $Q> K$

It means that forward reaction is faster than reverse reaction at that point. Because then only concentration of NO is higher than concentrations of $[N_{2}]$ and $[O_{2}]$ which makes Q higher than K.

Two commonly used sulfonic acids are methanesulfonic acid (CH3SO3H) and trifluoromethanesulfonic acid (CF3SO3H). Which acid's co

cluponka [151]

Answer:trifluoromethanesulfonic acid (CF3SO3H).

Explanation:

The trifluoromethanesulfonic acid (CF3SO3H) has a halogen atom which stabilizes the leaving group by withdrawal of charge from the SO3- moiety. The methanesulfonic acid (CH3SO3H) contains an electron pushing group which tends to destabilize the charge centre. The better leaving group will be the stabilized anion which in this case is trifluoromethanesulfonic acid (CF3SO3H). This typifies the role of stabilizing factors in formation of chemical species.
