Question

4 fill in the blank 1 point please determine a reasonable formula for a few common minerals. the main elements present are listed, in some cases with specific proportions (al2 in formula). hint: when oxygen is present, most other elements will take on a positive charge. quartz: si type your answer... o type your answer...

Explanation:

Step1: Determine oxidation states

Silicon (Si) has an oxidation state of +4 and oxygen (O) has an oxidation state of - 2 in most compounds.

Step2: Balance charges

To balance the charges, for one Si(+4) atom, we need 2 O(-2) atoms.

Answer:

$SiO_{2}$
