Answer:
Explanation:
Sodium benzoate forms when benzoic acid reacts with sodium bicarbonate. Since benzoic acid is readily soluble in ether than water, the salt of benzoic is more soluble in water than in ether because it is ionic and very polar. water which is the lower layer will contain sodium benzoate.
After separating the lower layer, if acidified with Hcl,benzoic acid will be regenerated, it precipitates out as a result of its low solubility in water.
<u>Answer:</u> The correct answer is Option C.
<u>Explanation:</u>
To calculate the number of moles, we use the equation:

Given mass of methane = 48.2 g
Molar mass of methane = 16 g/mol
Putting values in above equation, we get:

According to mole concept:
1 mole of compound contains
number of molecules.
So, 3.0125 moles of methane will contain =
number of molecules.
Hence, the correct answer is Option C.
The answer is D: studying how the mayfly population affects the number of trout in a stream <span> As the science of ecology studies interactions between individual organisms and their environments.</span>

Explanation:
Answer:
+2
Explanation:
If a compound
existed, we would identify the oxidation state of sulfur using the following logic:
- oxygen is more electronegative than sulfur, so it's more electron-withdrawing and it should have a negative oxidation state producing a positive oxidation state for sulfur;
- oxygen typically has an oxidation state of -2;
- we may then apply the fact that SO is expected to be a molecule with a net charge of 0;
- if the net charge is 0 and the oxidation state of oxygen is -2, we may set the oxidation state of S to x;
- write the equation for the net charge of 0 by adding all individual charges of the two atoms:
; - hence, x = 2.
That said, in this hypothetical compound S would have an oxidation state of +2.
