States of Matter
The substance that constitutes everything in the universe is known as matter. Matter comprises atoms which in turn are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction, namely solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).
Chemical Reactions and Equations
When a chemical species is transformed into another chemical species it is said to have undergone a chemical reaction. It consists of breaking existing bonds and forming new bonds by changing the position of electrons. These reactions are best explained using a chemical equation.
Consider the following substance: CH3CHO. Which intermolecular forces are present? (Please follow the steps below to write the answer)
-
- Indicate a 'plan' on how you intend to solve YOUR problem.
- You should have a numerical list. These can be phrases (not complete sentences) if you want, as long as the material is sufficiently easy to follow.
- Steps should be detailed. For example, "look in the book for the equation" does not work as you could not use that step while taking exams.
- Show the step by step solution of the problem.
- Using your plan, (and labeling each step), solve your predicted exam question.
- Show your work. For example, if you have a scientific notation question, you CANNOT say "move the decimal" but must illustrate each step of the process. If one step requires dimensional analysis to solve you can show your set up using arrows like I do in our videos - but show all of your work.
- Explain each step of your process.
- Arrive at the answer in this section.
- Present your "Final Answer."
- Your answer in its correct form should be presented or reiterated. Units, correct notation, sig figs, etc should be considered.
- Your answer should be correct for your problem.
