Chemistry is the study of
matter
properties
reactions
When writing the formula of an ionic compound,
all of these
the net charge must be zero
the total positive charge equals the total negative charge
the cation is written first followed by the anion

All carbon containing compounds are classified as being organic.
False
True

Hydrocarbons are organic compounds containing only hydrogen and
carbon
the carbonate ion
oxygen

The distinguishing feature of an alkene is that it contains
a double bond
a triple bond
an ionic bond
all single bonds
