Question

1. write the formulas for the following compounds in the space provided: a) carbon dioxide k) nitrogen monoxide b) silicon dioxide l) tetraphosphorus decoxide c) water m) silicon carbide d) carbon disulfide n) methanol e) ammonia o) diphosphorus pentabromide f) carbon tetrachloride p) arsenic tribromide g) methane q) carbon monoxide h) ozone r) sulfur dioxide i) fluorine s) neon j) diphosphorus trioxide t) dinitrogen tetroxide

Explanation:

Step1: Recall naming - compound rules

Use prefixes to denote number of atoms.

Step2: Write formulas for remaining compounds

b) Silicon dioxide has 1 silicon and 2 oxygen atoms, so formula is $SiO_{2}$.
d) Carbon disulfide has 1 carbon and 2 sulfur atoms, formula is $CS_{2}$.
e) Ammonia has 1 nitrogen and 3 hydrogen atoms, formula is $NH_{3}$.
f) Carbon tetrachloride has 1 carbon and 4 chlorine atoms, formula is $CCl_{4}$.
g) Methane has 1 carbon and 4 hydrogen atoms, formula is $CH_{4}$.
h) Ozone is $O_{3}$.
i) Fluorine is a di - atomic molecule, formula is $F_{2}$.
j) Diphosphorus trioxide has 2 phosphorus and 3 oxygen atoms, formula is $P_{2}O_{3}$.
k) Nitrogen monoxide has 1 nitrogen and 1 oxygen atom, formula is $NO$.
l) Tetraphosphorus decoxide has 4 phosphorus and 10 oxygen atoms, formula is $P_{4}O_{10}$.
m) Silicon carbide has 1 silicon and 1 carbon atom, formula is $SiC$.
n) Methanol has 1 carbon, 4 hydrogen and 1 oxygen atom, formula is $CH_{3}OH$.
o) Diphosphorus pentabromide has 2 phosphorus and 5 bromine atoms, formula is $P_{2}Br_{5}$.
p) Arsenic tribromide has 1 arsenic and 3 bromine atoms, formula is $AsBr_{3}$.
q) Carbon monoxide has 1 carbon and 1 oxygen atom, formula is $CO$.
r) Sulfur dioxide has 1 sulfur and 2 oxygen atoms, formula is $SO_{2}$.
s) Neon is a noble - gas, monatomic, formula is $Ne$.
t) Dinitrogen tetroxide has 2 nitrogen and 4 oxygen atoms, formula is $N_{2}O_{4}$.
