Answer:

A , 210.3 g

Explanation:

Given data:

Number of moles of SiO₂  = 3.50 mol

Mass of SiO₂ = ?

Solution:

Formula:

Number of moles = mass/molar mass

Molar mass of SiO₂ = 60.08 g/mol

by putting values,

3.50 mol = mass/60.08 g/mol

Mass = 3.50 mol × 60.08 g/mol

Mass = 210.3 g

Chlorine (CI) can be found as an ion with a 1- charge. How does this happen?
Lesechka [4]

Answer:There are 18 electrons and 17 protons, so the chlorine atom has become a charged chlorine ion with a charge of negative one (-1). ... When it does, the sodium atom becomes a sodium ion with a charge of positive one (+1). Chlorine, as mentioned above, desperately wants an electron so it can fill its outer electron level.
