"reactant" is a correct and usable word in written English.
You can use it to refer to a substance or mixture of substances involved in a chemical reaction. For example, "The reaction produced an unusual side-reactant."
Gasification processes use one or a combination of three reactant gases: oxygen (O2), steam (H2O), and hydrogen (H2).
Establishing that a reaction is of the first order kinetically (that is, behaves as though only one molecule of the reactant is involved in the transition state) with respect to one of the components, for example, seldom reveals whether or not one or more molecules of solvent also is involved in the transition state.
Chemical intermediate, any chemical substance produced during the conversion of some reactant to a product.
In the redox reaction the electrons are passed from one reactant to another.
Temperature is influential because reactions occur only if collisions between reactant molecules are sufficiently energetic.
The product will then be formed at a rate governed by the expression k1[A][C], in which the square brackets indicate concentrations of reactant and catalyst.
Anions of weak acids dissolve in water to give basic solutions, as in the hydrolysis of the acetate ion, CH3C OO−.CH3COO−(aq) + H2O ll) → CH3COOH aq) + OH−(aq) Although this is a reactant-favoured reaction, it occurs to an extent sufficient to cause a solution containing the acetate ion to exhibit basic properties (e.g., turning red litmus paper blue).
Whether the equilibrium lies toward the reactants (reactant-favoured) or the products (product-favoured) is determined by the relative strengths of the acids and bases.
The hot gas breaks up the reactants into atoms of carbon, hydrogen, silicon and oxygen.
A variant of this reaction occurs in some bacteria, in which ATP and inorganic phosphate are reactants and AMP and inorganic pyrophosphate are products; as mentioned above, inorganic pyrophosphate is likely to be hydrolyzed to two equivalents of inorganic phosphate, so that the net balance of the reaction is identical with [56].
Heteropolymolybdates and heteropolytungstates are always prepared in solution, usually after acidifying and heating the theoretical amounts of reactants.
