Drain Cleaner, soap, bleach
i think thats it, sorry if i got something wrong
Answer:
This makes it isoelectronic with krypton. The anion of bromine is Br-. The element rubidium has an electronic number 37. It loses one electron to gain a positive charge and change to Rb+ which has 36 electrons and is a cation that is isoelectronic with krypton
Answer: D) More moles of ions are present in a given volume of 0.10 M 
than in the same volume of 0.10 M NaCl.
Explanation:
A electrolyte is a solution that dissociates completely when dissolved in water. The ions act as good conductors of electric current in the solution.
More is the number of ions , more will be the conductance and hence the solution will be a better conductor of electricity.
0.10 M aqueous solution of is a better conductor of electricity as it dissociates to give three ions whereas 0.10 M aqueous solution of 
dissociates to give two ions only.
Thus 0.10 M aqueous solution of sodium sulfate, , is a better conductor of electricity as more moles of ions are present in a given volume of 0.10 M than in the same volume of 0.10 M
Fractinal distillation is used in the production of gasoline, distilled water, xylene, alcohol, paraffin, kerosene, and many other liquids.
Answer:
a) COCl₂.
b) The molecular formula is COCl₂.
Explanation:
To obtain empirical formula of phosgene you should divide elemental compositions over atomic mass of each atom, and divide these results between the smallest, thus:
C = 12,14%/12,01 = 1,01
O = 16,17%/16 = 1,01
Cl = 71,69%/35,45 = 2,02
Empirical formula:
C = 1,01/1,01 = 1
O = 1,01/1,01 = 1
Cl = 2,02/1,01 = 2
C₁O₁Cl₂ ≡ COCl₂
b) You need to find the molar mass of the empirical formula to determine the ratio of the real formula, thus:
1×C 12,01g/mol =
1×O 16 g/mol =
2×Cl 35,35g/mol = 98,91g/mol
As real molecular mass is 98,9 g/mol. The molecular formula: COCl₂
I hope it helps!
