Answer:
The answer to your question is: 1, 2, 1, 2
Explanation:
1 Fe(s) + 2 Na⁺(aq) → 1 Fe²⁺(aq) + 2 Na(s)
Fe⁰ - 2e⁻ ⇒ Fe⁺² Oxidases
Na⁺ + 1 e⁻ ⇒ Na⁰ Reduces
1 x ( 1 Fe⁰ ⇒ 1 Fe⁺²) Interchange number of
2 x ( 2Na⁺ ⇒ 2 Na⁰ ) electrons
I believe it is the mechanical organ.
Answer:
%age Yield = 66.05 %
Explanation:
In order to check the efficiency of a reaction the %age is calculated so that it can be concluded that either the conditions provided for certain reactions are favourable or not because at large scales reactions with greater %age yields are favoured as it results in high product quantity and hence, greater economical advantages.
The percent yield is given as;
%age Yield = Actual Yield / Theoretical Yield × 100
Putting values,
%age Yield = 253 g / 383 g × 100
%age Yield = 66.05 %
Hence, for the given reaction the success of the reaction is only 65% hence, steps can be made to improve this yield by modifying the reaction conditions.
The best answer to the question presented above would be letter a. Changing the pressure of a system has the highest effect on a gaseous phase. Solids and liquids under pressure make little difference, while gas molecules have many behaviors due to change in pressure.
Well, the answer relies on all four factors, I mean on all options. So, the answer is A, B, C, and D.
