Answer:
1. The correct option is;
c. maintains charge balance in the cell
2. The correct option is;
c. +3.272 V
Explanation:
The aqueous solution in a galvanic cell is the electrolyte which is a ionic solution containing that permits the transfer of ions between the separated compartment of the galvanic cell such that the overall system is electrically neutral
Therefore, the aqueous solution maintains the charge balance in the cell
2. Here we have;
B₂ + 2e⁻ → 2B⁻ Ecell = 0.662 V
A⁺ + 1e⁻ → A Ecell = -1.305 V
Hence for the overall reaction, we have;
2A + B₂ → 2AB gives;
(0.662) - 2×(-1.305) = +3.272 V.
Answer:
a scientific question
Procedure
Conclusion.
Explanation:
Scientific investigation is usually carried out to explain and give answers to natural phenomenon. Now, this scientific investigation is performed through the three main types as described in the question.
With that being said, the most common parts of all types of investigation are :
1. Scientific question: In this stage, questions are usually asked on the basis of observation made which could be answered.
2. Procedure: In this stage, the dimension of the steps are followed to answer and test the scientific question.
3. Conclusion: This is the primary aim that we check when done with our sample values

Suspension mixture was their dinner if they were having spaghetti and meatballs. The right option is D.
Explanation:
Properties of suspension mixture are:
Bigger particles are seen in suspension, and they are visible by naked eye.
Suspension is a heterogenous mixture of either two or more substances.
Solute particles are not dissolved in solvent instead they are suspended as it is or in bulk.
Exhibits Tyndall effect.
Solid particles get sedimented easily.
A mixture of spaghetti and meatballs are suspension because two paricles are not dissoved, and they have separate phases on sphagetti and meat ball where liquid in meat ball drizzles to bottom and meatball remians on top.
