According to the arrhenius concept, an acid is a substance that a. is capable of donating one or more h⁺b. tastes bitter c. reacts with the solvent to form the cation formed by autoionization of that solvent d. causes an increase in the concentration of h⁺ in aqueous solutions e. can accept a pair of electrons to form a coordinate covalent bond

Achemical equilibrium between gaseous reactants and products is shown. n2(g) + 3h2(g) ⇌ 2nh3(g) how will the reaction be affected if the pressure on the system is increased? it will shift toward the reactant side as there is lower pressure on the reactant side. it will shift toward the product side as there is higher pressure on the product side. it will shift toward the reactant side as there are a greater number of moles of gas on the reactant side. it will shift toward the product side as there are a fewer number of moles of gas on the product side.
