or the solution containing Zn2+(aq), n is 2, so the MM/n ratio will be the molar mass of Zn divided by 2: MM/n = (65.39 g/mol) /

2 = 32.70 g/mol Compare this theoretical value with your experimental result. If the plating efficiency is significantly less than 1, say it is 0.55, how would the observed MM/n ratio compare to the theoretical value?

Answer:

MM/n will be less than the theoretical value

Explanation:

Provided that

The plating efficiency is proportional to the element weight

i.e.

\frac{Zn^2}{(aq)}

That represents \frac{MM}{n\ value}

So,

MM by N value is

= 65.39 g /mol ÷ 2

= 32.70 g/mol

Also, the experimental plating value is 0.55 that represents that it is much lesser than the normal value

So it would be concluded that the MM by N would be lower than the theoretical value

lisov135 [29]

Answer:

90%

Explanation:

Data obtained from the question include:

Actual yield = 585g

Theoretical yield = 650g

%yield =?

%yield = Actual yield /Theoretical yield x100

% yield = 585/650 x 100

% yield = 90%

Brilliant_brown [7]

Answer:

It is a physical change.

Explanation:

While it is a chemical reaction because the salt gets dissolved, if you were to   boil the water off of a salt solution, all that would be left is salt. This can be done physically. Thus, it is a physical change.

Which is not a product of the fractional distillation of petroleum?
Natalka [10]
Answer:
            Option-C, <u>STEEL</u> <span>is not a product of the fractional distillation of petroleum.

Explanation:
                   Petroleum is the mixture of Hydrocarbons *carbon and hydrogen containing compounds) present beneath the Earth's surface. Petroleum is formed from the remains of animals and plants beneath earth's surface in an anaerobic conditions.
                   Petroleum contains from small hydrocarbons (gases) to medium (liquids) and long chain hydrocarbons (Solids). These hydrocarbons are separated from each other by Fractional Distillation method (separation due to difference in boiling points)
                   Gasoline is a derivative of one of the fraction of petroleum used in internal combustion engines.
                   Jet Fuel is also derived from Kerosene and Naphtha fractions of petroleum.
                   While, Steel is inorganic Alloy (mixture of metals) composed of mainly Iron, Carbon and other elements.</span>
