A certain metal forms a soluble nitrate salt M(NO3)3. Suppose the left half cell of a galvanic cell apparatus is filled with a 3
DiKsa [7]

Answer:

1.The electrode on the right is positive

2. 0.058V

Explanation:

The above cell is a concentration cell.

A concentration cell is an electrolytic cell that is made of two half-cells with the same electrodes, but differs in concentrations of the solutions. A concentration cell functions by diluting the more concentrated solution and concentrating the more dilute solution, creating a voltage as the cell reaches an equilibrium thereby transferring the electrons from the cell with the lower concentration to the cell with the higher concentration.

In the above cell, electrons flow from the left electrode (less concentrated) to the right electrode (more concentrated). Therefore, the right electrode is the positive electrode (cathode).

Part 2: Please, see the attachment below for the calculations.

Alenkinab [10]

Answer:

4 protons, 5 neutrons, 4 electrons to have the neutral Be atom

the only way to make a negative Be is to have more than 4 electrons

Explanation:

Make a neutral Beryllium atom by adding protons, neutrons and electrons. Now, what would you do to make a

beryllium atom with a negative charge?

Be has an atomic number of 4, an atomic mass 9

its atomic number tells us it has 4 protons, with a +4 charge

its atomic mass = neutrons + protons, so it has 5 neutrons with no charge

its neutral atom will have 4 electrons each with a negative charge to balance the +4 total proton harge.

so

4 protons, 5 neutrons, 4 electrons to have the neutral Be atom

to make a negative Be species, it still must have an atomic number of 4,

or it is not Beryllium

so the only way to make a negative Be is to have more than 4 electrons
