Chemistry Chapter 1/chapter 2 Part 1

gases – A state of matter, have no fixed shape and take on the shape of the space they're in
sodium perchlorate – Give the name for NaClO4
(MLS ONLY) After a difficult venipuncture requiring prolonged application of tourniquet, the serum K+ was found to be 6.8 mEq/L (6.8 mmol/L). The best course of action is to:
a repeat the test using the same specimen
b adjust the value based on the current serum Na+
c repeat the test using freshly drawn serum
d cancel the test – c repeat the test using freshly drawn serum
suspension – Suspension: particles in a solvent are so large that they settle out unless mixture is constantly stirred or agitated
Particle size: over 1000 nm, suspended; can be large particles or aggregates
Particles settle out
Can be separated by filtration
May scatter light, but are not transparent
Mixture – a collection of matter that is composed of two or more pure substances
Oxidation – Loss of electrons.
How many valance elecrons does carbon have?
Weak Base – Does not contain OH in its formula. pH is lower.
Boiling – The process by which a substance changes from its liquid phase to its gas phase
Aufbau Principle – electrons in atoms fill orbitals where they have the lowest energy first.
Relative Formula Mass – The sum of the atomic masses of elements in a compound. The formula mass expressed in grams
Which of the following is the formula for calculating absorbance given the percent transmittance(%T) of a solution?
a 1 – log(%T)
b log(%T)/2
c 2 x log(%T)
d 2 – log(%T) – d 2 – log(%T)
diffusion – Movement of molecules from an area of higher concentration to an area of lower concentration.
Dehydration Synthesis/Condensation – H from one atom is removed an OH from another, forming H20.
Hоw mаny vаlаnce elecrоns dоes carbon have?
What is a reversible reaction?

Give 3 examples – A reversible reaction is not a permanent reaction and will break back down into the reactants

Polar will dissolve other _____ substances. – Polar
** This follows the general rule that "like dissolves like"
Mixture – Made of two or more different components which are not chemically joined together
Chemical bonding – Elements join with others based on number of electrons
solute – Substance being dissolved
