When you carry out a chemical reaction in the lab the reactants are usually not in stoichiometric amounts. In other words, you probably don't have the proportions that are indicated by the balanced chemical equation. This means that at some point you will use up one of the reactants, a...

In a chemical reaction, reactants that are not used up when the reaction is complete are called excess reagents. To calculate the excess reagent, you need to find molecular weight then work out molarity.
After 51.0 min, 10.0 % of a compound has decomposed. What is the half life of this reaction assuming first order kinetics? A first-order reaction has a half-life of 26.9 s. How long does it take for the concentration of the reactant in the reaction to fall to one-fourth of its init...

The essence of all this manipulation can be summarized in a single statement. The standard Gibbs free energy for any reaction is just the sum of the standard Gibbs free energies of formation of the products minus the sum of the standard Gibbs free energies of formation of...
In a chemical reaction, how many reactants can there be? Can there be only 1 reactant? And same for products, can there only be one product? What happens to a catalyst during a chemical reaction? How do you find the mole ratio in a chemical reaction?
<p>To find out how long it took Lauryn Williams to run the actual distance of 100 meters, we need to subtract her reaction time from her total race time. Here’s how to do it step by step:</p><p><strong>Step 1: Identify the Given Information</strong> - <
The electrons in the dye atoms jump to a higher level, then fall back down, releasing energy in the form of light. The glow stick itself is just a case for the two solutions involved in the reaction — essentially, it's a portable chemistry experiment. The Glow Stick Activator - Hydrogen...
chemical sense this is more or less on target: A normalized preparation is one that has been created in proportion or relation to an established standard. To discover how to calculate the normality of NaOH, or how to convert from normality to molarity (another core chemistry concept), read ...
