Reactant

  • (noun): A chemical substance that is present at the start of a chemical reaction.

Some articles on reactant, reactants:

Synthetic Compound - Strategies
... strategies exist in chemical synthesis that go beyond converting reactant A to reaction product B ... chemical transformations take place within a single reactant, in multi-component reactions up to 11 different reactants form a single reaction product and in a telescopic ...
Abundance (chemistry)
... In a chemical reaction, a reactant is considered to be in abundance if the quantity of that substance is high and virtually unchanged by the reaction ... Abundance differs from excess in that a reactant in excess is simply any reactant other than the limiting reagent the amount by which a reactant is in excess is often specified, such as with terms like ... the reaction go to completion, the quantity of the reactant in excess will have halved ...
Chemical Kinetics - Factors Affecting Reaction Rate - Physical State
... state (solid, liquid, or gas) of a reactant is also an important factor of the rate of change ... When reactants are in the same phase, as in aqueous solution, thermal motion brings them into contact ... the reaction is limited to the interface between the reactants ...
Lanthanide Trifluoromethanesulfonates - Lewis Acid Catalysis
... forms a polar coordinate with a basic site on the reactant (such as an O or N) Its electrons are drawn towards the catalyst, thus activating the reactant The reactant is then able to be transformed by a substitution ...
Limiting Reagent - Method 2: Comparison of Product Amounts Which Can Be Formed From Each Reactant - Example
... Which reactant is limiting if 20.0 g of iron (III) oxide (Fe2O3) are reacted with 8.00 g aluminium (Al) in the following thermite reaction? Since the reactant amounts are given in ... Moles produced of from reactant Moles produced of from reactant There is enough Al to produce 0.297 mol Fe, but only enough Fe2O3 to produce 0.250 mol Fe ...
