Question 5 why does grinding solid crystals increase the rate of dissolving for a solid solute in water? smaller crystals are more polar. smaller crystals are more nonpolar. smaller crystals have more energy. smaller crystals have more surface area. none of the above

Chemical kinetics what was the rate of reaction in trial 3? choose the closest answer.

An atom of lithium-7 has an equal number of(1) electrons and neutrons(2) electrons and protons(3) positrons and neutrons(4) positrons and protons

How does a catalyst increase the speed of a reaction? a. the catalyst eliminates the activated complex stage, allowing products to form immediately. b. the catalyst lowers the energy level of the reactants, making it easier for them to react. c. the catalyst makes it easier for the activated complex to form, lowering the activation energy. d. the catalyst raises the energy level of the products, making the reaction finish sooner. reset next
