Spectator ions are the ions on the right side of the equation which do not combine to form products.
You have a typo in your formula (looks like a .jpg pic link you tried to paste), but we can see that potassium ions (K+) and bromine ions (Br-) appear unreacted on both sides of the equation. Therefore, the correct answer is C) K+ and Br-
Additionally, we know from solubility rules that Group 1 ions (including potassium, K, remain soluble in aqueous systems, meaning they do not combine with other ions and form products.
It increases by one to the right and decreases by one to the left, except transition elements
(first column always has 1 valence electron)
column refers to groups, so group 1 has 1 valence electron, group 2 has 2 valence electron and so on
I would assume its A, considering water, while able to dissolve many things, can't dissolve everything
It is known that 1 mol of a substance is equal to 6.02x10^3 particles. This is called the Avogadro's number. From this knowledge, we convert the mass of the substances given above into units of moles by using the molar mass.
12.01 g C ( 1 mol / <span>12.01 g) = 1 mol
44.08 g SiO2 ( </span>1 mol / <span>60.08 g ) = 0.73 mol
16 g of O3 (</span>1 mol / <span>48 g) = 0.33 mol
16.04 g CH4 (</span>1 mol / <span>16.05 g ) = 0.99 mol
So, the answers are carbon and </span><span>carbon tetrahydride</span>.
Answer:
sunlight is the answer i think
