B. An element from group 17

C. An element from group 1

B. An element from group 17

200

Name this compound: KF

Potassium fluoride

300

The name of this compound Ni₂O₃ is

nickel (III) oxide

400

When naming ionic compounds, the cation is always named first and the anion is always named second

A. True

B. False 

A. True

Always name the cation before the anion

500

How can you tell if it's an ionic compound?

A. It if contains a metal at the beginning

B. If it shares electrons to make eight

C. If it contains a non-metal

A. It if contains a metal at the beginning

Ionic compound (Ternary)

100

what is the formula for sodium perchlorate

NaCIO₄

200

what is the compound name for SnO

tin (II) oxide

300

What is the charge of a hydroxide ion?

-1

When water ionizes one of the hydrogen atoms absconds with itself and leaves it's electron behind, giving us the hydroxide ion. The extra electron gives hydroxide a net charge of -1

400

Li₂CO₃

A. lithium carbonoxide

B. lithium carbonate

C. lithium bicarbonate

B.  lithium carbonate

500

what is the formula for ammonium acetate

NH₄CH₃COO

Covalent compound (inorganic)

100

Name the covalent compound BF3

boron trifluoride

200

Which of the following is an example of an inorganic compound?

A. Glucose (C6H₁₂O₆)

B. Methane (CH₄)

C.Water (H₂O)

C.Water (H₂O)

The major inorganic compounds are water (H2O), bimolecular oxygen (O2), carbon dioxide (CO2), and some acids, bases, and salts.

300

what is the covalent compound formula for dinitrogen pentoxide?

N₂O₅

400

Name the covalent compound P₄O₁₀

tetraphosphorous decoxide

500

Name the covalent compound XeF6

xenon hexafluoride

Acidic compound (binary)

100

What is the name of the acid form of a Fluorine ion?

A. Fluoric acid

B. Difluoric acid

C. Hydrofluoric acid

C. Hydrofluoric acid

200

What is the formula for phosphorous acid? 

H₃PO₃

300

When making a binary acid, one must add the prefix hydro to the main element, then add the suffix "-ous

A. true

B. False

B. False

Explanation: When making a binary acid, one must add the prefix hydro to the main element, then add the suffix "-ic".

400

H₂Se

hydroselenic acid

500

hydrophosphoric acid

H₃P

Acidic compound (ternary)

100

nitrous acid

HNO₂

200

When making phosphoric acid, what is the equation?

A. HPO₄

B. PO₄

C. H₃PO₄

H₃PO₄

300

Make this poly-anion into an acid. Chlorite?

A. Chlorous Acid

B. Chloric acid

C. Hydrochlorous Acid

A. Chlorous Acid

The suffix "-ous" indicates a lower oxidation state of chlorine, which is the case in chlorite. hydrochlorous acid, and chloric acid are not the correct answers because they do not accurately represent the addition of hydrogen ions to the chlorite poly-anion

400

When naming a ternary acid, one must use the following rules? ( There are 3 right answers)

A. If the polyanion is "-ite", then it is "-ous".

B. If the polyanion is "-ate", then it is "-ous"

C. No Prefix of Hydro

D. If the polyanion is "ate", then it is "-ic".

A,C, and D

just remember that there is No Prefix of Hydro. If the polyanion is "ate", then it is "-ic". If the polyanion is "-ite", then it is "-ous"  (only for ternary compound).
