Question

1. Choose one of the compounds from the table and explain how you know the numbers of atoms in your formula. 2. Is it possible for two different compounds to be made from the exact same two elements? Why or why not? With a limited number of elements (less than 120 are known), does this mean we also have a small number of compounds or do we have a large number of compounds in this world?

Answer 1

Sodium Hydride=NaH which has 1 sodium atom, and 1 hydrogen atom, i know this because there are no added numbers meaning theres one of each element.

yes you can form different compounds with the same elements. An example of separate compounds with the same elements are CO & CO2, CO has 1 carbon atom with one oxygen atom and is a flammable gas vs CO2 has 1 carbon atom and 2 oxygen atoms and is a non flammable. Therefore we knowCO & CO2 are two different compounds with the same elements.

Even though there is a limited # of elements there are a plethora of compounds due to being able to combine the same elements with different atom ratios.
