Answer:
4
Explanation:
I guess it says more about the problem
The electronegativity values are not given, but covalent bonds occur between two nonmetals.
To solve this we use the equation,
M1V1 = M2V2
where M1 is the concentration of the stock solution, V1 is the volume of the stock solution, M2 is the concentration of the new solution and V2 is its volume.
.675 M x V1 = .25 M x 1.3 L
V1 = 0.48 L or 480 mL
If HCl is poured on an unknown substance and no precipitate forms it can be concluded that the substance is not a base or an alkaline substance. HCl is an acid and acids and bases always react to form a salt and water. The precipitate that would be expected to form would be the salt and the water formed would be in the solution.
