which statement best describes balancing equations and the law of conservation of mass? there are more atoms in the reactants than in the products, and the total mass is the same in the reactants and in the products. the number of atoms is the same in the reactants and in the products, and the total mass is the same in the reactants and in the products. there are fewer atoms in the reactants than in the products, and the total mass is less in the reactants than in the products. there are more atoms in the reactants than in the products, and the total mass is higher in the reactants than in the products.

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.
