Answer: An atom is the sub-component of a molecule, or the smallest unit of matter. It is the smallest part an element can divide into. A molecule is made up of atoms that are bound by ionic, covalent or metallic bond.
This is a really hard one just tell your teacher its not like she/he will get mad for not doing one question and think you will get it
Answer:
Explanation:
Hello there!
In this case, for this chemical equilibrium problem, it turns out possible for us to solve for the equilibrium concentrations by firstly setting up the equilibrium expression:
Thus, by plugging in an ICE chart, in terms of x (reaction extent), we can write:
And could be solved for x as follows:
Therefore, the equilibrium concentrations turn out to be:

Explanation:
Hello!
In this case, since the neutralization reaction between hydrofluoric acid and barium hydroxide (both aqueous) produce insoluble barium fluoride and liquid water, we can write the chemical reaction as follows:
However, it needs to be balanced as hydrogen and fluorine are not properly balanced, therefore, we obtain:
