Answer:
Because atoms could not be seen, Dalton could not base his theory on direct observation, and this was a major stumbling block for many scientists. ... It was easier to express stoichiometric proportions in terms of atoms than in terms of absolute mass.
Explanation:
Answer:
The correct answer is having more surface area
Explanation:
Reaction rate can be defined as the amount of substrate is converted into product per unit time .Reaction rate also called reaction velocity.
The reaction rate can be increased by increasing the surface area so that many reactant molecules can participate in the reaction as a result the reaction rate is being increased.
On the other hand decreasing the amount of reactant,diluting the solution and lowering the temperature decreases the reaction rate.
