When naming an ionic compound, write the name of the cation, which is the metal first. Then, write the name of the anion, which is the nonmetal. However, you remove the last 2-3 letters and replace suffixes.
1. RbF --> Rubidium Fluoride
Change fluorine to fluoride
2. CuO --> Copper (II) Oxide
Change oxygen to oxide. Oxide has a charge of -2. Since no subscripts are written, it means they have the same opposite charge. So, we use Copper (II).

NH₄ is ammonia, but we change it to ammonium for polyatomic ions.
total pressure = ( 705 torr + 231.525torr) = 936.525torr
Answer:
E = 4.78×10^−19 J
Explanation:
The chemical equation for the energy of a photon is given by:
E =hν , where h is the Planck constant and ν is the frequency.
E =hν = 6.626×10^−34 Js × 7.21×10^ 14
s−1 = 4.78 × 10^−19 J
<u>Answer:</u> There is no predicate adjective in the sentence.
<u>Explanation:</u>
Predicate adjective is defined as an adjective that follows the linking verb and modifies the subject of the linking verb.
For Example:
The shoes look expensive.
In this sentence, the shoes are the subject, 'look' is the linking verb and 'expensive' is the predicate adjective.
The predicate adjective modified the subject.
In the given sentence,
'Five' is a common noun, 'cookies' is the subject, 'are' is the helping verb, 'on' is the preposition, 'the' is an article and 'table' is a countable noun.
Hence, there is no linking verb and therefore, this sentence has no predicate adjective.
