Answer:
Vegetable oil will dissolve in heptane
Isopropyl alcohol will dissolve in water
Potassium Bromide will dissolve in water
Explanation:
In chemistry, like dissolves like. This implies that polar substances will dissolve in polar solvents and nonpolar substances will dissolve in nonpolar solvents. This is so because, dissolution of a solute in a solvent involves adequate intermolecular interaction between solute and solvent which isn't possible between a polar and a nonpolar substance.
Answer:
True
Explanation:
The chemical method of separating two compounds depends on their difference in solubility in water, ether, dilute acid or alkali. Separatory funnel thus, are used to distinguish immiscible fluids from their solutes. The funnel is usually made of glass, pear-shaped, and usually contains a stopper and a stopcock.

Answer:
Mechanical advantage is a measure of the force amplification achieved by using a tool, mechanical device or machine system. The device preserves the input power and simply trades off input forces against movement to obtain a desired amplification in the output force. The model for this is the law of the lever.
Explanation:
I believe the pH is 7. If you would like me to explain comment.
