The greatest molar amount of metal product is obtained from silver (1) nitrate.
Let us determine the mass of metal obtained in each case.
For La^3+;
La^3+ + 3e ----> La
1 mole of La is deposited by 3F
x moles of La is deposited by 10 F
x = 1 × 10/3
x = 3.33 moles
For Zn^2+;
1 mole Zn^2+ is deposited by 2F
x moles of Zn^2+ is deposited by 10 F
x = 5 F
For Ag^+
1 mole of Ag^+ is deposited by 1 F
x moles of Ag^+ is deposited by 10 F
x = 10 moles
For Ba^2+;
1 mole of Ba^2+ is deposited by 2 F
x moles of Ba^2+ is deposited by 10 F
x = 5 moles

Explanation:
Population is hugely dependent on the environment and it's factors. The physical, chemical and biological components of the environment plays vital roles in the sustenance of all life on earth.
A change in the environment can lead to terrifying consequences. Let's examine some of the changes:
- Climate change can lead to flooding of biological habitats and where people typically reside. This can lead to death and loss of life.
- Drought can lead to decline in food production. During a drought, a place receives little to no rainfall and the land is not fit for agricultural practices. This will eventually lead to famine.
- Pollution: it is the introduction of harmful substances into the environment. Pollution is harmful to the population.
- Geological hazards; earthquakes, volcanic eruptions,mass wasting and so on can lead to a crash in population.
- Wildfires, tornadoes, dust bowls e.t.c are changes in the environment that can cause severe consequences on the population.

Answer:
State Newton's first law of motion in your own words. According to Newton's first law of motion, the state of motion of an object does not change as long as the net force acting upon the object is zero. ... These two forces are called the action and reaction forces.
