I would say that the answer has to be C
Since there is no change in mols on both sides of the equation the mass is constant
Answer:
NaCl dissolves into the water and dissociates into Na⁺ and Cl⁻ ions, present homogeneously throughout the solvent
SiO₂ settles down at the bottom of the vessel in the form of coarse particles
Explanation:
NaCl is a strong electrolyte that is, it dissociates readily in an aqueous solution. So when the water is added in the mixture, NaCl dissolves readily and is present uniformly in the solvent as Na⁺ and Cl⁻ ions.
SiO₂ has a strong ionic bond and is not dissociated by water, so it is present in the form of coarse particles at the bottom of the vessel.
Answer:
balanced because the total number of oxygen atoms is 3.
Answer:
because dark colors attract heat so if your clothes are light you won't be as hot as if you were wearing dark colors.
Generally, when an acid and a base are added together in solution, a salt and water will form. This is known as an acid-base reaction. Therefore, the scientist may infer that she is working with an acid. (Acid + Base = H2O + Salt).
