Sebastian wants to write the chemical formula for phosphorus tetraoxide. which steps will he take at some point in his process? check all that apply. identify the elements involved as potassium and oxygen identify the symbols as p and o write the chemical symbols, in order, as op use the prefix tetra before oxygen add a subscript of 4 after the o

Explanation:

A chemical formula is defined as symbolic representation of a molecule or compound.

The number present as a subscript in a chemical formula depicts the number of atoms of each element present in the compound.

For example, chemical formula of phosphorous tetraoxide is .

The symbol P represents the element phosphorous and symbol O represents the element oxygen.

Since, 4 atoms of oxygen are involved. Therefore, a prefix "tetra" is mentioned. And, a suffix "-ide" is placed at the end of oxygen and it will be written as an oxide.

This means that tetra is placed before oxide and not before the word oxygen.

Thus, we can conclude that steps taken by Sebastian at some point in his process are as follows.

a. hope i'm right

explanation:

the density of gold = 19.3 g/cm3

the relation between density and mass and volume is

density = mass / volume

given :

mass of gold = 13 g

density = 13g / volume = 19.3

volume = 13 /19.3 = 0.67 cm^3

thus volume of gold nugget = 0.67 cm^3
