A limiting reactant is the substance that is fully consumed during a chemical reaction. Once the limiting reactant has been fully consumed, the chemical reaction stops. In some instances, the limiting reactant is known a... More »

To determine the limiting reagent, you must first determine the balanced equation for the chemical reaction. Convert every unit given into moles, then adjust the balanced equation for every one of the reagents. Use stoic... More »

In the equation H2 + N2 → NH3, the reactants are both H2 and N2. In this equation, the two reactants of hydrogen and nitrogen react to form ammonia gas. In a chemical equation, the components on the left side are the rea... More »

Titration is a technique that finds the concentration in a substance by using a known reactant. By gradually adding the reactant to the solution, eventually there's a change indicator that helps determine the concentrati... More »

A confirmatory test is a controlled chemical reaction used to determine the presence of a specific ion or compound in a solution or substance. Confirmatory tests are commonly used after an experiment in a laboratory sett... More »

Burning a match is a chemical reaction because the reactant, primarily wood, is chemically altered into a different substance, ash. A chemical reaction or change involves one or more reactants having bonds broken or alte... More »

The molecules of one reactant are combined with those of another reactant to form a new substance during a chemical reaction. As the chemical bonds are broken, the positions of electrons change, resulting in a product wi... More »
