Answer:
Hydrocarbon being non polar are soluble only in non polar solvent.
Explanation:
Hydrocarbon molecules either have very little polarity or they do not have polarity at all, this is because of absence of electro-negative atoms in their molecular structure. Due to this their solubility is also affected. The solubility of a compound depends on its polarity as it can dissolve in a polar solvent only when it is polar or else they are soluble in non-polar solvent
Answer: -7.5
Explanation: To solve for y in the equation -3/(y + 6) = 2, you can follow these steps:
First, we want to get rid of the fraction. To do that, multiply both sides of the equation by (y + 6) to cancel out the denominator:
-3/(y + 6) * (y + 6) = 2 * (y + 6)
This simplifies to:
-3 = 2(y + 6)
Now, distribute 2 on the right side of the equation:
-3 = 2y + 12
Next, isolate the term with 'y' by subtracting 12 from both sides of the equation:
-3 - 12 = 2y
-15 = 2y
Finally, divide both sides by 2 to solve for 'y':
-15/2 = y
So, the solution for y is:
y = -15/2
You can also express this as a mixed number:
y = -7.5

a) The concentrated solution has the same amount of solute as the dilute solution.
b) The concentrated solution has more solute than the dilute solution.
c) The concentrated solution has a different amount of solute than the dilute solution.
d) The concentrated solution has the same amount of solute as the dilute solution.
Answer: b) The concentrated solution has more solute than the dilute solution.
Explanation:-
Binary Solution is a homogeneous mixture of two components called as solute and solvent. Solute is the component which is present in smaller proportion and is solid for solid in liquid solution and solvent is the component which is present in larger proportion and is liquid for solid in liquid solution.
Concentrated solution is one in which there is more amount of solid.
Dilute solution is one in which there is more amount of liquid.
If water is added to 100 ml of a 0.15 M NaOH solution until the final volume of 150 ml. The molarity of the diluted solution is 0.1 mol. L.
Molarity is the measure of the concentration of any solute per unit volume of the solution.
Moles of solute is
Volume is 150 ml
Putting the value
Thus, the molarity of the diluted solution is 0.1 mol. L.

Answer: The correct answer is Option C.
Explanation:
Oxidation state is the number which is assigned to an element when it gains or looses electrons. If the element gains electron, it will attain a negative oxidation state and if the element looses electrons, it will attain a positive oxidation state.
We take the oxidation state of iron atom be 'x'.
Oxidation state of oxygen atom = -2
Evaluating the oxidation state of iron atom in :
Hence, the correct answer is Option C.
