When chemical equation is balanced then what is equal?
When a chemical equation is balanced, the number of atoms of each element on the reactant side is equal to the number of atoms of the same element on the product side. This ensures that the law of conservation of mass is upheld, as no atoms are created or destroyed during a chemical reaction.
If heat is produced by a chemical system?
If heat is produced by a chemical system, it means that an exothermic reaction is taking place. In an exothermic reaction, heat is released to the surroundings as a byproduct of the reaction. This can result in an increase in temperature of the system.
Why is a rotting Apple a reaction in which energy in neither absorbed nor released?
The chemical energy in the reactants is almost equal to the chemical energy in the products
If 16 ounces of a chemical solution in 5 gallon of water equal 500 ppm how many ounces of chemical are needed to make one gallon?
To calculate the amount of chemical needed per gallon, first determine the total amount of chemical in the 5 gallons of water. Since 16 ounces in 5 gallons equal 500 ppm, you can set up a proportion: (16 ounces/5 gallons) = (x ounces/1 gallon). Solve for x to find out how many ounces of chemical are needed per gallon.
How is the law of conservation of matter best represented in a chemical reaction?
The Law of Conservation of Mass states that mass cannot be created or destroyed. In a chemical reaction that means that the number of a certain element on one side must equal the same amount on the other.

What law is the basis for the amount of reactants and products being equal in each chemical reaction?
Conservation of mass.
Is the chemical reaction of baking cookies a balanced chemical reaction?
The reactants and products need to be equal, as the supplies you put into the cookie mix has to be the same amount of cookies you get after.
Why is a rotting Apple a reaction in which energy in neither absorbed nor released?
The chemical energy in the reactants is almost equal to the chemical energy in the products
When a chemical change occurs what do you know about the amount of matter in the new substances What is this known as?
In a chemical change, the amount of matter in the new substances remains constant. This is known as the law of conservation of mass, which states that matter cannot be created or destroyed in a chemical reaction, only rearranged.
In most chemical reactions the amount of product obtained is?
In most chemical reactions, the amount of product obtained is determined by the limiting reactant, which is the reactant that gets completely consumed first, leading to the maximum amount of product that can be formed based on the stoichiometry of the reaction.
What is the concept of equivalence in chemistry and how is it used to determine the amount of a substance in a chemical reaction?
In chemistry, equivalence refers to the equal amount of reacting substances involved in a chemical reaction. It is used to determine the amount of a substance by comparing the number of equivalents of different substances involved in the reaction. This helps in calculating the stoichiometry and quantities of reactants and products in a chemical reaction.

What happens to the energy when its released when firewood is burned?
when the wood burns, chemical reactions occur that change chemical potential energy into thermal energy and light enery. Well, the released energy just simply turns into thermal and light enery.
What is is the principle of conservation of mass?
The amount of matter involved in a chemical reaction does not change. The total mass of the reactant must equal the total mass of the products.
What is a balanced chemical equation Why should chemical equations be balanced?
A balanced equation is when the amount of molecules reacting are equal to the amount of molecules being produced. Chemical equations must be balanced because no energy/mass is ever lost when a reaction takes place. This is because atoms are simply arranged.
