Chemical Formula Review

The purpose of this semester long experiment was to determine an unknown organic acid. An organic acid is an organic compound with acidic properties. A base reacts with acids to form salts. Titrations are used to determine the concentration of unknown substances. The purpose of the KHP experiment was to determine the molarity of NaOH. HCl titrations are mainly to check technique and used to verify the molarity of NaOH solution. The hypothesis is that this acid is C4H3OCOOH.

* Alkenes are saturated hydrocarbons. They contain as many hydrogen atoms as possible in their molecules.

The formula of the simplest possible compound containing only C and I atoms is CI4.

alcohol, making it either primary (1° ), secondary (2° ), or tertiary (3° ). If the OH is bonded to only one other carbon, it is a primary alcohol (eg. 1-butanol); if bonded to two other carbons, it is a secondary alcohol (eg. 2-butanol); if bonded to three other carbons, it is a tertiary alcohol (eg. 2-methyl-2-propanol). Due to the placement of the hydroxyl functional group in each of the degrees of alcohol, the reactivity of each should be impacted. This means that all three

A) They feature carbon atoms which are covalently bonded to hydrogen (Open Learning Initiative, 2015, pg.63).

When you name compounds the first element is usually called the same as the element's name like magnesium or iron. The second element usually has the -ide ending except when you use the prefixes. Some names end in ite or ate when you have a polyatomic. This is why MgBr2 is magnesium bromide, but it could also be called magnesium dibromide. This also explains why some compounds use di- and tri- prefixes, such as carbon disulfide and dinitrogen pentoxide. Roman numberals are needed when you have transitional metals in the compound because all transitional metals can have different charges, so you have to memorize them or you can look at the periodical table to see the group numbers which are equal to the charges so then you put the charges into

1-1: Insert the chemical symbol in the answer blank for each of the following elements.

~ ~ is the simplest, and most important of the Alkenes. It is one of the most important Petrochemicals

38. When naming binary ionic compounds, write the name of the positive ion (cation) first,

Determine how many covalent bonds an atom needs in order to fill its valence shell, using the periodic table.

xv. Or, more commonly: methane gas, ammonia, arsenic, chloromethane, iron, manganese, t-butyl alcohol, toluene. (Bradford County)

The empirical formula that was determined was different from that of the “true” compound mentioned. The empirical formula determined was:

have five C-H bonds, one C-C bond, one C-O bond and one O-H bond. To

By using the pH paper to measure the solutions A through E it would point out what substance is an acid and which one was basic. Also, by adding Bromothymol blue and Phenolphthalein afterwards to the solution it would indicate what color it would turn to when mixed into an acid and a base.

For example, are cotton sheets organic? You might think so because cotton is a natural fiber. However, most cotton sheets aren’t considered to be organic because cotton is almost always treated with pesticides. This is because cotton is very susceptible to parasites and struggles to grow without this extra protection. Additionally, most cotton bedding isn’t organic because it is
