Answer: 
Explanation:
The unbalanced equation is
Balancing this equation, we get:
Answer:
The law of conservation of mass states that mass in an isolated system is neither created nor destroyed by chemical reactions or physical transformations. According to the law of conservation of mass, the mass of the products in a chemical reaction must equal the mass of the reactants.
Explanation:
How does the concept of conservation of mass apply to chemical reactions? the reactants and products have exactly the same atoms. the reactants and products have exactly the same molecules. the change in the amount of matter is equal to the change in energy.
can someone help me with my qustions?
Answer:
There are 2 types of forces, contact forces and act at a distance force. Every day you are using forces. Force is basically push and pull. When you push and pull you are applying a force to an object.
Explanation:

I believe it's (3)
Explanation:
same number of proton and electrons in both atoms A and atom B. but different number of neutron
All of the energy from the reactants will be lost to the surroundings.The energy found in the reactants remains in the system, and the reactants also take energy from the
surroundings is true of energy in reactants during endothermic reaction.
<h3>What is Endothermic reaction?</h3>
Endothermic reaction is a reaction in thermochemistry where the reactants absorb heat from the surrounding to form the products.
In an endothermic reaction, the products have more energy than the reactants, that is they absorbed more energy. The reactants have less energy,that is they loss energy . Therefore, the change in enthalpy is positive, heat is absorbed from the surroundings during the reaction.
Therefore, All of the energy from the reactants will be lost to the surroundings.
The energy found in the reactants remains in the system, and the reactants also take energy from the
surroundings is true of energy in reactants during endothermic reaction.
