For example 20g of NaCl are dissolved in 100ml of water. Thus, HCl is the solute, water is the solvent, and together they make a solution.

Dilution is a common type of problems given to students in the concentration chapter of their chemistry class. To dilute something means to add water to the solution, which will in turn decrease the concentration.
The formula for dilution is M1V1= M2V2
where M1= Molarity 1
V1 = Volume 1
M2 = Final Molarity
V2= Final Volume
Note, that for this formula your volume can be in any units as long as it is consistent on both sides.
Solution: In order for us to answer this question we must know how to identify strong acids and strong bases. We have to memorize strong acids in order to be able to identify them. Strong acids are: HCl - hydrochloric acid, HNO3 - nitric acid, H2SO4 - sulfuric ac...
Hydrogen bonding will be exhibited by molecules who have OH, NH, or FH bonds. These forces are especially strong and influence the boiling point and melting point of the substances that contain them. That is why water H2O has an unusually high boiling and melting point. In organic chemistry substances such as alcohol, amines, and carboxylic acids are the ones that will have hydrogen bonding and will have unusually high...

Since regent is a standardized exam, doing a lot of practice is key to your success. Start by doing an exam in the red regents book and going over the explanations in the back for the questions you got wrong or were not sure about. This will also help to identity your weak areas that you can review further with the blue regents book. Do as much practice and as many exams possible. Make sure to und
An electrolyte is the substance that is able to conduct electricity. Electricity is the flow of charged particles. Therefore, in order to be an electrolyte, we need to have charged particles. We can remember 3 types of substances that are electrolytes: metals, ionic compounds dissolved in water and strong acids/bases. To be a...
