Question

1. we use chemical formulas to represent individual molecules and groups of molecules. write the chemical formula below each molecule or groups of molecules. a. b. c. d. e.

Explanation:

Step1: Identify atoms in a

There are 2 carbon - like and 2 oxygen - like atoms. So the formula is $CO_2$.

Step2: Identify atoms in b

There is 1 oxygen - like and 4 hydrogen - like atoms. So the formula is $H_4O$. But the common way is to write water as $H_2O$, here it might be a wrong - order representation or a non - standard one. For the given structure, we assume it's $H_4O$.

Step3: Identify atoms in c

There are 6 oxygen - like atoms. So the formula is $O_6$.

Step4: Identify atoms in d

There are 6 nitrogen - like atoms. So the formula is $N_6$.

Step5: Identify atoms in e

There are 8 hydrogen - like atoms. So the formula is $H_8$.

Answer:

a. $CO_2$
b. $H_4O$
c. $O_6$
d. $N_6$
e. $H_8$
