There can be three mole ratios that can be written involving three substances.It depends on the constant of your reactant to your product. It also depends on the asked mole ratio. But the maximum would be 3 mole ratios because you have 3 substances in your reaction.
Answer : 3 substance will have 3 mole ratios to be written for a chemical reaction.
Explanation : The mole ratio can be defined as the ratio between the amounts in moles of any two or more compounds involved in a chemical reaction.
It can be determined by comparing the coefficients the formulas of a balanced chemical equation. It is also known as the molar ratio or mole-to-mole ratio.
Hence, when 3 substances are involved in a chemical reaction 3 mole ratios can be written for it.
I'd say that his comb has a static electricity charge. It can either be negative, or positive. Let's just say it's positive, and the water is negatively charged. This means that it will affect the water flow when the two charges meet. I hope this helps! ~Mia
