A soild reactant placed into a beakerof warm warer the liquid vigorously bubbles as the soild dissolves into the solution what most likely happen if the temperature of the liquid is slightly reduced?

If a solid reactant is placed in a beaker of warm water and the temperature was slightly reduced after it dissolved, it may produce more bubbles as a result of more heat escaping.

Chemical reactions will occur independently of the reactant's temperature?
false
What is the reactant called that gets used up first?
The Limiting Reactant is the reactant that runs out first in a reaction.
You can speed up a reaction if you break the solid reactant into smaller pieces what factor does this describe?
When you break up a solid into smaller pieces it dissolves faster when you have big pieces of the solid you have to wait for the substance that is dissolving it ti be picked up by the object that is being dissolved but when the pieces are smaller it dissolves faster because their smaller and the substance dissolving the object get picked up much faster
Is sodium acetate a reactant or a product?
reactant
How limiting reactant control a reaction?
Using an excess of another reactant limits a reactant.
Chemical reactions will occur independently of the reactant's temperature?
false
Why does surface of a reactant influence the rate of the reaction?
A chemical reaction is nothing but the conversion of the reactant molecules into product molecules. By increasing the surface area of the reactants more number of reactant molecules are exposed which eventually increases the rate of the reaction...for example, powdered chalk piece dissolves faster in water than a piece of chalk.
Do chemical reactions occur independently of the reactant's temperature?
Almost all chemical reactions are dependant of the temperature that it takes place.

Why is a reaction between steam and a metal quicker than with just water and a metal?
Temperature is something that can hinder or catalyze a reaction. In order for molecules to combine and rearrange, they have to not only line up correctly, but hit with sufficient force. By increasing the temperature of a reactant, you are increasing the speed of the particles. This is the same way with steam vs. water: the steam, with a higher temperature, will react more vigorously with the metal because the molecules will "bump" into more metal atoms more times, and also with more force.
Will increasing the temperature cause an increase in the rate of a reaction?
increased temperture causes rate or reaction to increase.
Is copper oxide a reactant or product?
It can be either depending on the reaction. It can be a product of electrolysis of copper with sulfuric acid, or an acid base reaction of copper hydroxide and sulfuric acid. It can react with metals such as zinc.
What is the reactant called that gets used up first?
The Limiting Reactant is the reactant that runs out first in a reaction.
How factors affect rates of physical change?
-Reactant Concentration • The greater the concentration of reactants (the more particles per unit volume), the greater will be the number of effective collisions per unit time, and therefore, the reaction rate will generally increase. • For zero order reactions, however, the reaction rate is not dependent on the concentration of reactants. Increasing the reactant concentration will have no effect on the rate. -Temperature • The reaction rate will increase as the temperature of the system increases. As the temperature increases, the reactant molecules have more energy. They thus find it easier to climb the energy barrier to the reaction (the activation energy). -Solvent • The reaction rate will increase as the temperature of the system increases. As the temperature increases, the reactant molecules have more energy. They thus find it easier to climb the energy barrier to the reaction (the activation energy).
How many liters of hydrogen gas are formed from 6.0 g of HCl and 5.0 g of mg?
Assuming we are at standard temperature and pressure (STP), the answer is approximately 1.85L of hydrogen gas. The HCl is the limiting reactant and the Mg is the excess reactant.
