Explanation:
Vapor pressure is defined as the pressure exerted by vapors or gas on the surface of a liquid.
When interaction between the solute and solvent are weak then solution will evaporate readily into the atmosphere. Therefore, it means vapor pressure increases with particularly weak solute-solvent interactions.
On the other hand, when interactions between the solute and solvent of a strong enough in a solution then vapors are not formed easily. This also means that vapor pressure decreases with particularly strong solute-solvent interactions.
First you look at your empirical evidence, secondly you see if your explanation is logical, third you look at other tests you can do to support your idea.
Answer:3
Explanation:
nitrogen is in the 5th column and needs 3 electrons to achieve the desired 8 electrons
Since both sides have to be equal to each other, subtracting the left side from the right side will leave you with the other reactant.
On the right side, you have 1 sodium, 2 carbon, 5 hydrogen, and 3 oxygen.
If you take away 1 sodium, 1 oxygen, and 1 hydrogen you are left with 2 carbon, 4 hydrogen, and 2 oxygen.
This is written as CH3COOH
AKA Acetic Acid
Explanation:
With all the scaling up and design improvements, the flight range of the R-7 increased to an intercontinental distance from 330 kilometers for the V-2. The R-7 ended up looking oversized even next to its American contemporaries -- the Atlas and Titan ballistic missiles.
