Answer:
Mass percent of silicon = 46.75% (Approx)
Explanation:
Given:
Mass of silicon = 0.389 g
Mass of silicon dioxide = 0.832 g
Find:
Mass percent of silicon
Computation:
Mass percent of silicon = Mass of silicon / Mass of silicon dioxide
Mass percent of silicon = [0.389 g / 0.832 g]100
Mass percent of silicon = 46.75% (Approx)
Answer: The Answer is 0.3.
Explanation: Solved in the attached picture.
I think the answer is D, PCl5. Ionic compounds are compounds made up of ions. These ions are atoms that gain or lose electrons to form a stable configuration, thus attaining a net positive charge or negative charge. Metals tend to lose electrons thus they become cations and have a net positive charge. On the other hand non-metals tend to gain electrons, forming anions that have a net negative charge. Phosphorus chloride is not an ionic compound since it is made up of phosphorus and chlorine which are both non metals.
