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...

Finding the Limiting Reactant When Given Mass of Reactants Now that you know how to find the limiting reactant, take a look at this example. Aluminum chloride can be made by reaction aluminum and chlorine: \(2Al+3Cl_2 \rightarrow 2AlCl_3\) What is the limiting reactant if you have...
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.
You can create new experiments using an existing one as starting point by using the “Cloning” option. You will find this option very useful when repeating experiments using different conditions, etc. The structured nature of the DESK working space allows you to neatly record your chemistry.Relat...
Why do reactants become hotter during exothermic reactions when they are losing energy and why do reactants become colder when they are gaining energy in endothermic reactions? What are the entropy changes with catabolic reactions? How could you perform an experiment to find the melting point of...
Step 1:Determine the reaction order with respect to the first reactant. First, we will find the reaction order of NO. The comparison of experiments 2 and 3 is as follows: rate3rate2=k[NO2]x[O3]yk[NO2]x[O3]y We will now plug in the experimental data. ...
How to calculate the rate of reaction in chemistry? How many grams of N2 will be produced in 49.26 L of H2 that reacts at a temperature of 300 K and 3 atm pressure? N2+ 3H2 rightarrow 2NH3 How do you find the rate constant of a reaction?
I know what they mean, but in a very early set of problems they ask us to predict how certain reactants would pair up or change in the products. And I could figure out mostly how the reactants would pair up, but really had no idea if it would be a gas, liquid, or solid. Is...
In chemistry, a mole is a quantity used relate reactants to products in stoichiometric equations. A mole of any substance is equal to 6.02 x 10^23 particles -- usually atoms or molecules -- of that substance. For a given element, the mass (in grams) of o
