Answer:
Part B : Hg
Part C : Ag
Explanation:
When we added ammonium hydroxide to the solid remains after addition hot water , AgCl dissolve due to the formation of soluble complex [Ag(NH3)2]+ and Hg2Cl2 gives black precipitate with ammonium hydroxide due to formation of elemental mercury.
Black precipitate is not formed upon addition of amonium hydroxide to the precipitate remains after addition of hot water, so Hg22+ is shown not to be present.
The precepite remains after addition of hot water is dissolved by the addition of ammonium hydroxide, so Ag+ may be present. The presence of Ag+ is not confiremed by K2CrO4 test.
Your answer would be B: "Matter is made up of atoms"
C-12 and C-13 are isotopes of the element carbon. Since they are both of the same element, they have the same number of protons. The number that follows the C indicates the number of neutrons. Isotopes are variations of the element with different number of neutrons. C-12 shows that that variation of carbon has 6 protons and 6 neutrons for a total mass of 12. C-13 shows that it has 6 protons but 7 neutrons for a total mass of 13
