Answer:
The balanced chemical equation is P₄ (s) + 5O₂ (g) → P₄O₁₀ (s)
Explanation:
In order to balance the chemical equation, you first need to see what's out of balance.
In this case our Oxygen is not balanced, so in order to make the two the same, we need to see what coefficient we need to add to the compounds to balance the problem.
So, adding a coefficient of 5 to the O₂ will result in an equal number of oxygen on both sides.
The Hot water of the cofee is the SOLVENT, Sugar is the SOLUTE, and this means the sugar molecules must be HYDROPHILIC
Name for the compound HF is Hydrogen fluoride.
Hope this helps!
