Answer:
79.904 g/mol
Explanation:
The molar mass of bromine is 79.904 g/mol.
Answer is: C is equal to 2, D is equal to 6 and E is equal to 1.
C, D and E represent number of electrons on each atomic orbital in sodium atom.
Electron configuration of sodium atom: ₁₁Na 1s² 2s² 2p⁶ 3s¹.
Atomic number of sodium is 11, it means that it has 11 protons and 11 electrons, so atom of sodium is neutral.
We have the compound: KSCN, Potassium thiocyanate, in an aqueous solution.
The dissociated reaction of the salt:
KSCN (aq) => K+ + SCN-
It has 2 ions. One of them is the potassium ion, K+ (cation) and the other one is the thiocyanate ion, SCN- (anion).
Answer:
K+, the potassium ion
SCN-, the thiocyanate ion
Answer:
The starch test also known as the iodine test is used to test for the presence of starch.
Sorry if this isn’t detailed enough. You can go on google/wikipedia and find much more detail if necessary. ^-^
