What Is a Measurement?
Comparison to an agreed upon standard.
Every measurement has a number and a unit
The unit tells you to what standard you are comparing your object.

Final Lab Report
Experiment 47- Diels-Alder Reaction
1. Experimental Procedure: First, 0.100g of maleic anhydride and 0.40mL of ethyl acetate was added
MODULE 2 UNIT 2 | Assignment Part B | Melissa Nelson
1. Why must two non-metals share electrons to form a bond? 4 marks
Ans: The two non-metals share electrons to form a bond because they
both need to gain electrons in order to acquire the electron config

Additional Multiple Equilibria Problem Example
Calculate the solubility of Co(OH)2 in water.
Co2+ + 2OH
H3O+ + OH
2) Define Unknown
solubility of Co(OH)2 = s = [Co2+]
3) K Expressions
Ksp = [Co2+][OH]2 = 1.3 x 1015
During the first week of lab you will check into lab space and learn about safety procedures and
rules. There will also be a short experiment this first week, so don't dawdle with check-in or
you'll run out of time.
The TA will give a short intro
Lab 7: Spectrophotometric Determination of Iron in Vitamin Tablets
Iron (Fe) is involved in many biological processes. The human body contains 4-6 g of iron,
most of which is in the blood as part of the protein hemoglobin. Hemoglobin is used to transfer
Lab 8: Determination of Riboflavin by Molecular Fluorescence
When a molecule absorbs a photon in the ultraviolet or visible regions (180 - 780 nm), an
electronic transition occurs. In this transition, an electron moves from the singlet ground state to
LAB 2: Standardization of Sodium Hydroxide and Determination of Potassium Hydrogen
Sodium hydroxide (NaOH) is a secondary standard. It is hygroscopic (water liking) and will
absorb water when exposed to the atmosphere. Therefore, weighing out so
LAB 4: Determination of Ascorbic Acid in Vitamin C Tablets
The compound referred to as vitamin C is ascorbic acid, C6H8O6. Commercial vitamin C
tablets contain a mixture of ascorbic acid and inert fillers or binders. Ascorbic acid can be
quantified in com
Lab 9: Determination of Copper by Atomic Absorption Spectroscopy
Atomic absorption (AA) spectroscopy is a very sensitive method for the determination of more
than 60 elements. When a solution of inorganic ions is aspirated into a flame, a substantial
LAB 10: Potentiometric Halide Titration with Ag+
The goal of this experiment is to determine the amount of KI and KCl in a mixture by a potentiometric titration with
AgNO3. The indicator electrode is made of silver metal and is used as an electrode of the
LAB 5: Determination of Carbonate and Bicarbonate in a Mixture by the Two-Indicator
There are several ways in which the concentrations of these two bases can be determined in a
mixture. The procedure we have chosen for this lab is the two-indicator
LAB 3: Gravimetric Determination of Chloride
The chloride content of a soluble sample can be determined by gravimetric analysis. In this
experiment, gravimetric analysis involves precipitation of silver chloride by addition of silver
nitrate to your disso
Electronic Structure of Atoms
Electronic structure includes the number of e- each atom
has & how they are positioned around the nucleus.
Well see that the arrangement around the nucleus is
essential for understanding the periodicity of elements in

Lab Practicum: Preparation of 4-chlorochalcone
Abstract: In this experiment, benzalacetophenones will be prepared by the reaction of a substituted
benzaldehyde, 3-nitrobenzaldehyde, with acetophenone in aqueous
Derived SI units
We can derive other units by combining the base SI units. For example,
speed is a combination of length and time:
speed = distance / time
The SI units for distance (length) and time are meters and seconds, so
the unit for speed is meters
Atomic Theory of Matter
The smallest particle of an element that
retains that elements chemical properties
is called an atom.
Atoms are neither created or destroyed in
Compounds are formed when more than
one type of atom combine.
If anion ends in ide, change the suffix to ic, and add prefix
If anion ends in ate, change the suffix to ic, but add no prefix.
If anion ends in ite, change the suffix to -ous, but add no prefix.
Molecules and Molecular
In nature, the noble gas elements are the
only ones found as isolated atoms
Other elements are found as either
molecules or ions
A molecule is a package of tightly
associated atoms, that behave as a single
