How do you identify which is the reactant and which is the product?
In a chemical reaction equation the reactants are the ones in the left side of theequal or arrow sign, and the products are the ones on the right side.i.e., Reactants → Products
Substances that enter a reaction are termed?
A substance which enters into a chemical reaction is called a reactant.In a chemical reaction-also called chemical change- one or more reactants (the initial substances that enter into the reaction) change into one or more products (the final substances that are present at the end of the reaction).
What speeds up chemical reactions?
to speed up a chemical reaction .. we use a catalyst
What is chemical equilibrium in a cell?
A cell in an isotonic stateWhere osmatic pressure is equal in and outside of the cellthe answer is: a chemical reaction in which both the reactants and products are only used in a metabolic pathway that is completely inactive
Which term describes the difference in the concentration of a substance across a cells membrane?
concentration gradient
What happens to the mass of reactants in a chemical reaction?
The reactants will form products, so the amount of reactants will decrease, proportionally to the increase in products. The amount can be expressed in mass, concentration or moles.
What are four ways that chemists can control chemical reactions?
increase in surface area, increase in temperature, increase the concentration of the reactants, and the presence of catalysts or inhibitors.
If you wish to increase the rate of a chemical reaction you might try increasing the concentration of the reactants. (True) or (False)?
(True)
What are substance you start with in a chemical reaction called?
The reactants
What conditions increase the rate of chemical reaction?
Many factors can and do increase the rate of chemical reactions. The most obvious is an increase in temperature, although too large an increase can breakdown the reactants. Other factors include catalysts, enzymes, pressure, concentration of reactants , surface area and other forms of energy (UV is an example).
What effect does the concentration of reactants have on the the rate of a reaction?
The effect of concentration of reactants on rate of reaction depends on the ORDER of the reaction. For many reactions, as the concentration of reactants increases, the rate of reaction increases. There are exceptions however, for example a zero order reaction where the rate of reaction does not change with a change in the concentration of a reactant.
What are the substance you start with in a chemical reaction?
The reactants
What is a starting substance of chemical reaction?
reactants
How does increasing pressure affect the reaction rate?
The concentration of reactants is changed.
When are reactants referred to as substance?
All reactants are compounds or elements.During a chemical reaction reactants are transformed in products.
The substance which undergo chemical change in areaction are called?
The initial substances in a chemical reaction are called reactants.
What speeds up in chemical reaction?
There are numerous ways to affect the speed of a chemical reaction. They are add a catalyst, increase the concentration of reactants, increase surface area of reactants, increase pressure, and increase the energy in the environment around the reaction.
