She should make soup. When you are way above sea level, the atmospheric pressure decreases. Boiling starts when the vapor pressure of the liquid is the same with the atmospheric pressure. This would mean that water boils at a much lower temperature than the usual 100deg C. So it would take longer for the components in the soup to cook compared to when it is cooked on the foot of the mountain.

Aleks04 [339]
<h3>Answer:</h3>

Atoms of elements on the reactants side

  • 2 Carbon atoms
  • 6 Hydrogen atoms
  • 7 Oxygen atoms
<h3>Explanation:</h3>
  • The equation; C₂H₅OH+ 3O₂ →2CO₂+ 3H₂O is balanced.
  • A balanced chemical equation has an equal number of atoms of each element on either side of the equation.
  • For example, in the equation given, the number of atoms of each element is equal on both sides of the equation.
  • There are 2 carbon atoms, 6 hydrogen atoms, and 7 hydrogen atoms on either side of the equation.
  • According to the law of conservation of mass, the mass of the reactants should be equal to the mass of reactants.
  • Therefore, chemical equations are balanced for them to obey the law of conservation of mass.
