Dancing Cheek to Cheek Trivia Quiz

Answer: Sodium Sulphide

Sodium sulphide is used in the production of paper, and can be found in OTC ingrown toenail relief products. It can cause skin burns if in contact with humans.

Naming binary compounds is the easiest in chemical nomenclature. Simply state the metal first, then the non-metal with the last suffix of "-ide" instead of its normal suffix. Oxidation numbers represent the charge (or charges) for an element. Here are some other binary compounds:

Li3P - Lithium Phosphide
CaCl2 - Calcium Chloride
NaF - Sodium Floride

Answer: FeCl2

Iron (II) chloride is used in water treatment to reduce chromates in the water.

The most common way to distinguish which oxidation state is to either put the number in Roman numerals between the two elements. The other way used in this example is only valid for those with exactly two oxidation numbers. Use the Latin word for iron, and add the suffix -ous or -ic depending on whether it is the lower or higher of the two oxidation numbers, respectively.

SnCl2 - Tin (II) Chloride OR stannous chloride
Pb3N4 - Lead (TV) Nitride OR plumbic nitride
FeBr3 - Iron (III) Bromide OR ferric bromide

Answer: Carbon Tetrachloride

CCl4 is used by stamp collectors to reveal watermarks without damaging the stamp. It has previously been used in lava lamps and fire extinguishers. It can also be called tetrachloromethane in organic chemistry.

Mono can be eliminated when dealing with the first of the two elements. Along with changing the second element's suffix to -ide, both elements need to have the correct prefix in front. These are the prefixes used:

1- Mono 2- Di 3- Tri 4- Tetra 5-Penta 6-Hexa 7-Hepta 8-Octa 9-Nona 10-Deca

Here are some other compounds that follow these rules:
Dinitrogen Pentoxide -N2O5
Selenium Hexaoxide - SeO6
Chlorine Dioxide - ClO2

Answer: Chlorate

Chlorate is a powerful oxidizer, and were once used in pyrotechnics. They are unstable when combined with combustible substances, so now perchlorates are used in fireworks.

Radicals can also gain and lose electrons. For each situation, these are the changes:

+1 oxygen: add prefix "per" (ClO4, perchlorate)
-1 oxygen: use suffix "ite" (ClO2, chlorite)
-2 oxygen: use suffix "ite" and prefix "hypo" (ClO, hypochlorite)

Answer: Nitric Acid

The most common use of nitric acid is in rocket fuel, and fertilizer. Nitric acid is used in woodworking to artificially age pine and maple wood. It is a very corrosive liquid as well.

The number of oxygens can vary in oxyacids, but in its original form the suffix -ic is added to the root of the middle element to name it. Here is the nomenclature for each outcome:

+1 Oxygen...add perfix "per" (HNO4, pernitric acid)
-1 Oxygen...use suffix "ous" instead of "ic" (HNO2, nitrous acid)
-2 Oxygen...use preifx "hypo" and suffix "ous" (HNO, hyponitrous acid)

Answer: Aluminium Sulphate

Aluminum sulphate is used to lower the pH of garden soil, and can be found in water purification. It has been the subject of controversy, as small traces are found in baking soda. Concerns have been raised over having aluminum in the diet.

Naming salts with radicals, are the same as normal ionic compounds, except the radical is left as is, and the suffix does not change. The radical naming rules also has to be correct as well. If it was SO3, than it would be sulphite, not sulphate, its general radical. The metal is left in its normal name. Some other radicals

Mg(ClO3)2 - Magnesium Chlorate
Mg(IO)2 - Magnesium Hypoiodite
Ca3(PO4)2- Calcium Phosphate

Answer: Hydrobromic Acid

Hydrobromic Acid is used mostly in chemistry, to form different forms of compounds.

Naming binary acids is also quite easy, as the hydro- is used to indicate hydrogen, and the root of the non-metal is included. The second word is always "acid". To top it of add the suffix "-ic" is put on the end. For example.

HI(aq) - Hydroiodic Acid
HCl(aq) - Hydrochloric Acid
HF(aq) - Hydrofluoric Acid

Note: Binary acids are formed once dissolved in water. HBr is hydrogen bromide if no water is present.

Answer: K2O2

Potassium peroxide is formed when potassium reacts in air with oxygen. There are not any common uses of the compound.

Note - With peroxides, the subscripts are not reduced. (in this case, to KO).

Naming peroxides is the normal cation (or metal) plus peroxide. Potassium Oxide is K20 (as oxygen has a charge of -1, and potassium's is +1) Here are some peroxide examples.

H2O2 - Hydrogen Peroxide
Mg2O3 - Magnesium Peroxide

Answer: Yes

NaHCO3 is baking soda, and has been used an antacid to reduce heartburn. Toothpastes, shampoos, deodorant and mouthwashes each contain it.

As usual, the metal is named first with its regular name. If only one hydrogen is in the compound, either "bi" can be added to the name of the radical (carbonate), or the word hydrogen can be placed in the middle. If multiple hydrogens are in the compound, there is only one method. "Dihydrogen" is placed in the middle between the metal and the radical. Having three or more hydrogens are impossible in these compounds. For example:

KH2PO3 - Potassium Dihydrogen Phosphate
Ca(HSO3)2 - Calcium Bisulfite OR Calcium Hydrogen Sulfite

Answer: Lithium Bromide Trihydrate

Lithium bromide has been used as a sedative, but was stopped in 1940 after being linked to deaths. It was used to treat bipolar disorder. As a hydrate, it has no uses.

The numerical prefixes used when naming hydrates are the same as the ones used in covalent compounds. The compound is named using normal bonding rules. The prefix is added to "-hydrate", and placed on the end of the name. Here are some more examples.

CuSO4 > 2 H2O - Copper Sulphate Dihydrate
Na2O > 5 H2O - Sodium Oxide Pentahydrate
