Do the numbers of atoms increase or decrease after the chemical reaction?

Yes, in chemical reactions atoms are neither created nor destroyed, nor changed from one kind to another. Those things can only happen in nuclear reactions. Chemistry deals with how atoms combine with one another.

∙ 14y agoThe numbers of each type of atom involved in a chemical reaction are always exactly the same before and after the reaction; only the bonds between the atoms change.

∙ 13y agoyes because energy cannot be created or destroyed so whatever you put into the equation you need to get back out
Wiki User
∙ 11y agoThe total number of atoms before and after a chemical reaction is the same.
Wiki User
∙ 11y agoThere will be neither a change in the number of atoms in a particular element nor a change in the number of overall atoms involved in a chemical reaction.
Wiki User
∙ 8y agoThe number of atoms and their type remain unchanged; only they are rearranged.

∙ 12y agoThey stay the same. Conservation of mass.

In a redox reaction the numbers of some of the elements changes from the reactants to the products?
In a redox reaction the OXIDATION numbers of some of the elements change from the reactants to the products. The numbers of atoms each element never changes in any chemical reaction.
Numbers that precede symbols and formulas in a chemical equation?
The numbers that precede symbols and formulas in a chemical equation represent the balance of atoms or molecules on each side of the equation. These numbers are coefficients and indicate the ratio in which the reactants combine or products are formed in the chemical reaction. They ensure that the law of conservation of mass is satisfied in the reaction.
A balanced chemical equation allows you to determine the?
A balanced chemical equation allows you to determine the ratio of reactants consumed and products produced in a chemical reaction. It also allows you to calculate the amounts of substances involved in the reaction based on the stoichiometry of the equation.
What is a method to indicate reactants and products of a chemical reaction using chemical formulas?
One common method is to write the chemical formulas of reactants on the left side of an arrow and the products on the right side. For example, the reaction between hydrogen gas (H2) and oxygen gas (O2) to form water (H2O) can be written as: 2H2 + O2 → 2H2O. The numbers in front of the formulas represent the balanced coefficients in the reaction.
Matter can be created during a chemical reaction?
No, matter is not created or destroyed in a chemical reaction. The total mass of the reactants before a reaction is equal to the total mass of the products after the reaction. This is known as the law of conservation of mass.
What are the similarities and difference between enzymes and chemical catalyst?
Enzymes and chemical catalysts both increase the rate of a chemical reaction without being consumed. The main difference is that enzymes are biological catalysts produced by living organisms, while chemical catalysts are typically synthetic or inorganic substances. Enzymes are typically more specific in their action and operate under milder conditions compared to chemical catalysts.
What does exponential mean?
Numbers that are raised to an exponent either increase or decrease at an extremely fast rate.
How do you find a percentage increase decrease between two numbers?
In order to find the percentage increase and decrease between to numbers are easy. All you have to is subtract the number you start out with to the number it becomes.
What chemical equation has equal numbers of reactant and product atoms?
Any chemical reaction.
What happens to the chemical reactivity of alkali metals as you increase atomic numbers?
The chemical reactivity of alkali metals increase when the atomic number increase.
What are some ways to describe the relationship between sets of numbers?
by their increase or decrease
What is the difference between multiplying and dividing?
when multiplying the numbers increase unless it is multiplied by a decimal, it will then decrease. when dividing the numbers are divided (splitted) therefor it decreases unless it is divided by a decimal, it will then increase. Decrease means 'gets smaller or less' Increase means 'getting bigger or more'
What does exponentially?
Numbers that are raised to an exponent either increase or decrease at an extremely fast rate.
What indicates the relative numbers of reactants and products in a chemical reaction?
The number of initial chemical compounds (reactants) and the number of final compounds resulted from the reaction (products).
What does not happen in a chemical reaction?
The total numbers of atoms of reactants do not change in products.
In a redox reaction the numbers of some of the elements changes from the reactants to the products?
In a redox reaction the OXIDATION numbers of some of the elements change from the reactants to the products. The numbers of atoms each element never changes in any chemical reaction.
What is an atom inventory?
Is a count of the numbers of atoms of each element in a compound or in a chemical reaction.
