• In the first and second video of balancing equation, I learned about reactant and product. As well as edentifying coefficients in a chemical equation the how to use the abbreviation in the physical state In video of the five major classe of chemical reaction it talk about Classify chemical reactions as synthesis (combination), decomposition, single displacement (replacement), double displacement, and combustion Electrolyte Electrolyte vs. nonelectrolyte a compound which produces ions when dissolved in a solution such as water. These ions have either a positive or negative electrical charge, which is why we refer to these compounds as electro-lytes . where the nonelectrolytr is a substance that does not readily ionize when dissolved or melted and is a poor conductor of electricity
