Assume that magnesium would act atom-for-atom the same as copper in this experiment. How many grams of magnesium would have been
Goshia [24]

Answer:

0.1127 grams of Mg is used to produce one gram of silver

Explanation:

Write a balanced equation

Mg(s) +2Ag + (aq) --> Mg^{2+}(aq) + 2Ag(s)

The atomic mass of magnesium is 24.31 g/mol and the atomic mass of silver is 107.84g/mol

1 g Ag of silver is produced from [(1 mol Mg)(24.31 g/mol)] /[ (2mol Ag)(107.84g/mol)]

1 g Ag of silver is produced from 0.1127 grams of Mg

0.1127 grams of Mg is used to produce one gram of silver

Which statement describes thermal energy?
Alona [7]

Answer: Option (d) is the correct answer.

Explanation:

Thermal energy is defined as the internal energy of an object because of the kinetic energy present within the molecules of the object.

So, when thermal energy is added to an object then kinetic energy within its molecules will also increase. As a result, temperature of the object will also increase due to increase in number of collisions between the molecules.

Therefore, we can conclude that the statement energy that is associated with temperature, describes thermal energy.
