___Al + ___O2 → ___Al2O3
4Al + 3O2 → 2Al2O3
Answer:
I'd say the answer is B) Load.
Hope this helps. :-)
The percent yield is given by the actual and the theoretical yield. The percent yield of the 2.73 gm compound is 80.3%. Thus, option b is correct.
<h3>What is the percent yield?</h3>
The percent yield is the ratio of the actual yield to the theoretical yield. It is calculated as:
% Yield = Actual yield ÷ Theoretical yield × 100%
= 2.73 ÷ 3.84 × 100%
= 71.09 %
As the closest number to 71.09 is 80.3% the percent yield will be 80.3%.
There is no limiting reagent in the reaction between the copper iodide and mercury iodide as the moles of the reactants and the products are in equal quantity.
Hence, option b. there is no limiting reagent in this reaction.

Answer:
1. The salt bridge completes the circuit of the voltaic cell to allow the flow of current
2. The porous divider performs the function of a salt bridge, hence a salt bridge is unnecessary in a single-beaker voltaic cell
Explanation:
1. The oxidation and reduction half cells of a voltaic cell are connected by the salt bridge in other to ensure that the internal circuit is electrically neutral, to avoid the rapid reaction to reach equilibrium conditions which affects results in preventing voltage drop in the voltaic cell.
The salt bridge also aids in charge accumulation
2. In a single-beaker voltaic cell with the compartments separated by a porous divider, the function of the porous divider is the same as that of the salt bridge, hence the salt bridge is unnecessary.
