When two substances react chemically to produce a new substance, what is TRUE of the mass of the two substances compared to the mass of the new substance? Select one: a. The mass of the two substances is less than the mass of the single substance. b. They have the same mass. c. The mass of the two substances is more than the mass of the single substance.

Respuesta :

Hint: conservation of mass

Answer:

b. They have the same masses.

Explanation:

Chemical reaction is defined as the process in which new substances are formed when two or more substance are react and the resultant substance posses different chemical properties.

The left hand side of the reaction is reactant and the right hand side of the reaction is product.

As we know that in the chemical reaction the number of atoms remain the same. Mass of the substance remains the same in the chemical reaction.According to conservation of mass, it can never be created nor be destroyed means total mass which takes part in chemical reaction will be conserved.
