In a chemical reaction, the total bond energy of the products must be lower than the total bond energy of the reactants for the reaction to be exothermic (energy released) and vice versa for an endothermic reaction (energy absorbed). This is based on the principle of conservation of energy.
What else can I help you with?
In a chemical reaction the mass of reactants must equal the mass of.?
In a chemical reaction, the mass of reactants must equal the mass of products. This is in accordance with the law of conservation of mass, which states that matter cannot be created or destroyed, only rearranged.
The correct terms for the two sides of a chemical equation?
given the law of conservation of mass, we now know that the mass of the reactants must equal the mass of the product.
The atoms in the products are what the atoms in the reactants?
Yes, the atoms on either side of the arrow have to be the same. Sometimes to achieve this you must balance the equation with the amount of atoms. 2Cu(s)+1/2O2(g)--->2CuO(s) Where the numbers in front of the atoms tell you how many there are.
Is the volume always equal as the reactants and products?
The volume of reactants and products in a chemical reaction can vary depending on the stoichiometry of the reaction and physical state of the substances involved. In many cases, the volume of reactants may not be equal to the volume of products due to the formation of new substances with different properties.
How does mass of the reactants compare with the mass of the products?
The reactants will have a slightly greater mass because as the reaction occurs the mass of the reactants will separate out into the products and in the process a small amount of the mass from the original reactants will be lost leaving the products with less mass than the original reactants.
What must be true about the properties of the reactants and the properties of the products in a chemical reaction?
The reactants and the products must contain the same numbers of the same types of atoms, that is, atoms with the same atomic number, and either the products must contain at least one type of chemical bond distinct from any chemical bond in the reactants or the reactants must contain at least one type of chemical bond not found in the products.
What must happen for reactants to be changed into product?
in order for reactants to be changed into products, there needs to be a chemical change.
In a chemical reaction the mass of reactants must equal the mass of.?
In a chemical reaction, the mass of reactants must equal the mass of products. This is in accordance with the law of conservation of mass, which states that matter cannot be created or destroyed, only rearranged.
If the products of a reaction are Narc and H'S what does the law of conservation of mass reveal about the reactants in the reaction?
The law of conservation of mass states that mass cannot be created or destroyed in a chemical reaction. Therefore, the total mass of the reactants must equal the total mass of the products. Since the products of the reaction are Narc and H'S, the mass of the reactants must be equivalent to the combined mass of these products, ensuring that all atoms present in the reactants are accounted for in the products.
Reactants and products in an energy diagram?
Activation energy is the distance from the reactants to the top of the "hill."
What chemical equation is properly balance?
The reactants must be balanced correctly with reactants.
The correct terms for the two sides of a chemical equation?
given the law of conservation of mass, we now know that the mass of the reactants must equal the mass of the product.
What must combined to create a chemical equation?
Reactants and products must be combined to create a chemical equation. Reactants are the starting materials that undergo a chemical reaction, while products are the substances that are formed as a result of the reaction.
What if the total mass of the product in a chemical reaction is 14grams what must the combined masses of the reactants be?
The mass of reactants is equal to the mass of products.
In a chemical balancing equation what is to the left and right?
In a chemical equation, the reactants are on the left side, while the products are on the right side. The number and type of atoms in the reactants must be equal to the number and type of atoms in the products for the equation to be balanced.
What is a balance equation that indicate that it is conserved?
The mass of reactants must be equal to the mass of products.
How do you kow when a chemical equation is balanced?
The number of atoms for reactants and products must be equal.
