Answer:
Variables and independent variables
The atomic number of hydrogen is 1
From the stoichiometry of the problem, 2.01 × 10^5 g of zinc phosphate is produced.
<h3>What is volume?</h3>
Volume is the product of width, height and depth. The significant figures of the width, height and depth are 5, 4 and 6 respectively.The volume of the box is; 11.014 × 10^-2 m × 0.2481 m × 523.735 × 10^-3 = 0.01431 m^3 or 14310 cm^3 or 0.5053ft^3.
Density of zinc = 7.140 g / cm3
Volume of zinc = 14310 cm^3
Mass of zinc = 7.140 g / cm3 × 14310 cm^3 = 102 Kg
Moles of Zinc = mass /molar mass = 102 × 10^3/65 g/mol = 1569 moles
There are 195 g of zinc in 386 g zinc phosphate
102 × 10^3 g of Zn will produce x g
x = 102 × 10^3 g × 386 g / 195 g
x = 2.01 × 10^5 g of zinc phosphate

Answer:
Right
Explanation:
The given parameters are;
The soluble sulfate formed by the metal, M = M₂SO₄
In the galvanic cell formed by the metal M, we have;
The concentration of M₂SO₄ in the left half cell = 50.0 mM = 0.05 M
The concentration of M₂SO₄ in the right half cell = 5.00 M
In the galvanic cell, the metal 'M' will be dissolved into the solution with lower concentration as M²⁺ which is the left half cell, making the cell negative and the solution more concentrated
In the right half cell, the metal 'M²⁺' in the solution will be plated unto the electrode making the solution less concentrated and the electrode in the right half cell will be the positive electrode
Therefore;
The electrode which will be positive is the electrode in the right half cell.
It is a devoid of matter and gaseous pressure and atmospheric pressure.
