Given a mole each for iron and magnesium, the number of atoms of each element is equal. Iron has a greater mass due to its greater molecular weight. The correct statement among the choices is D.

Answer: d) They both have the same number of atoms.

Explanation:

A mole is defined as the amount of substance that contains Avogardro number of the substance. Avogadro's number is given by 6.022\times 10^{23}.

1mole=6.022\times 10^{23}particles

According to avogadro's law, 1 mole of every substance weighs equal to its molecular mass and contains avogadro's number 6.023\times 10^{23}

Thus 1 mole of magnesium and iron both contains 6.023\times 10^{23} particles.

For each of the following choose the variable that will be more favorable in solution formation. A) Weak or Strong Solvent inter
Deffense [45]

Based on factors affecting solution formation;

  • Strong solvent-solute intermolecular forces favors solution formation.
  • Increase in entropy favours solution formation
  • Decrease in enthalpy favours solution formation

<h3>What is a solution?</h3>

A solution is a substance formed when a substance known as solute dissolves in another substance know as solvent.

Factors that affect solution formation include:

  • strength of intermolecular forces between solute and solvent
  • entropy
  • enthalpy

Strong solvent-solute intermolecular forces favors solution formation.

Increase in entropy favours solution formation

Decrease in enthalpy favours solution formation.
