How many different elements are in this equation? NaCl + AgNO3 --> NaNO3 + AgCl

5 elements

Explanation:

Na, Cl, Ag, N, O are all separate elements because the first letter of an element is always capital and the second one is lowercase

sodium, chlorine, silver, nitrogen, oxygen; therefore there are five different elements

hloride, what is the mass of calcium in

explanation:

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.
