State the law of conservation of mass. then apply the law to this question: what would be the total mass of the products of a reaction in which 25 grams of table salt ( sodium chloride) decomposes into the elements sodium and chlorine?

The total mass of the products will be 25 grams.

Explanation:

Law of conservation of mass states that mass can neither be created nor be destroyed but it can only be transformed from one form to another form.  This also means that total mass on the reactant side must be equal to the total mass on the product side.

The chemical equation for the decomposition of sodium chloride follows:

Let the mass of products be 'x' grams

We are given:

Mass of sodium chloride = 25 grams

Total mass on reactant side = 25

Total mass on product side = x

So, by applying law of conservation of mass, we get:

Hence, the total mass of products will be 25 grams

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.
