Answer:
Option C. Ksp for PbCl₂
Explanation:
The equilibrium constant that is established between a solid and its ions in a saturated solution is what is known as Ksp (solubility product). It is an equilibrium constant based on concentrations.
The concentrations must be equilibrium, that is, concentrations of the ions in a saturated solution. To be sure of such saturation it is convenient to form a precipitate.
The smaller the Kps, the more insoluble the salt
The answer should be "by convection" not by radiation.
Answer:
Total mass of the reactant = 2+2.5 =4.5 mg
Total mass of product = 4.15 mg
therefore, mass of unreacted oxygen = 4.50-4.15 = 0.35 g
Answer:
Love is an emotion you feel for someone or something very closely and enjoy spending time with them. Love can be a good thing and bad. It can be bad by being rejected by the person you like or even love. After that you might say you never want love again. But without love you might not be the person you are now. You now might know your mistakes and will do better the next time. Without love you won't have any cherishful moments. You might even turn depressed. But the past is the past, and you must look forward.
