When a chemical change occurs the products have a greater mass than the reactants?
The answer depends entirely on the type of chemical reaction.
If it's a chemical reaction that "splits" the molecules of the reactants into their constituent parts than no, the resulting number of atoms in the product would be equivalent to the sum of it's parts. Think dropping a magnesium strip in water, it splits the water into two hydrogen atoms and one oxygen, the magnesium strip burns off into a gaseous form.
However the nuclear reaction actually reduces the complexity of the molecules and their base parts (like chemical fission) into simpler forms (like actually changing one oxygen atom into 8 hydrogen atoms) then yes, the product would indeed have more atoms (though simpler) than the sum of it's parts.

What happens to the reactants when a chemical change occurs?
During a chemical change, the reactants undergo a chemical reaction to form new substances called products. The reactants are transformed into products with different chemical properties through the breaking and forming of chemical bonds. The reactant atoms are rearranged to form the products.
Which are the products and reactants of a chemical reaction most likely to have in common?
The products and reactants of a chemical reaction are likely to have similar chemical properties and structures. This is because the reactants undergo a chemical transformation to form the products, so they often share similar elements, functional groups, or bonding arrangements.
In a chemical equation where do the reactants appear?
In a chemical equation the reactants appears to be on the left side. On the left you have the reactants and to the right you have the products.
What is the equation for calculating the change in enthalpy of a system during a chemical reaction?
The equation for calculating the change in enthalpy of a system during a chemical reaction is H H(products) - H(reactants), where H represents the change in enthalpy, H(products) is the enthalpy of the products, and H(reactants) is the enthalpy of the reactants.
What are all the reactants of stoichiometry?
Reactants in stoichiometry are the substances that are consumed in a chemical reaction to form products. They are the starting materials that undergo a chemical change. The reactants are written on the left side of a chemical equation.
What happens to the reactants when a chemical change occurs?
During a chemical change, the reactants undergo a chemical reaction to form new substances called products. The reactants are transformed into products with different chemical properties through the breaking and forming of chemical bonds. The reactant atoms are rearranged to form the products.
What does a chemical change always do?
A chemical change always changes the chemical composition of the reactants to produce products with new and unique properties, different from the reactants.
Substances change after a chemical reaction is called what?
A chemical reaction is the transformation of reactants in products.
What is made in a chemical change?
From the reactants new products are formed.
What always occur in a chemical change?
The reactants are transformed in products.
Which are the products and reactants of a chemical reaction most likely to have in common?

In a chemical equation where do the reactants appear?
In a chemical equation the reactants appears to be on the left side. On the left you have the reactants and to the right you have the products.
What is the chemical change or reaction?
Transformation of reactants in new compounds (products) is a chemical reaction.
How do reactants and products participate in a chemical reaction?
Reactants are the starting materials that undergo a chemical change to form products. During a chemical reaction, reactant molecules collide and undergo chemical transformations to produce new molecules known as products. The reactants are consumed, while the products are formed as a result of the reaction.
What is the equation for calculating the change in enthalpy of a system during a chemical reaction?
The equation for calculating the change in enthalpy of a system during a chemical reaction is H H(products) - H(reactants), where H represents the change in enthalpy, H(products) is the enthalpy of the products, and H(reactants) is the enthalpy of the reactants.
What does change in a chemical reaction?
The reactants change. The chemical bonds between the atoms in the reactants break, and then new bonds are formed, which results in the formation of new products.
What are the products and reactants of a chemical change?
The products of a chemical change are the substances formed as a result of the reaction, while the reactants are the starting substances that undergo the change. In a chemical equation, reactants are on the left side and products are on the right side.
