Carbon Trioxide
Explanation:
Its a Carbonite Ion which is also known as a polyatomic ion
Answer:
1.4952 grams of sodium bicarbonate she would need to ingest to neutralize this much HCl.
Explanation:

Moles of hydrochloric acid = n
Volume of hydrochloric acid solution = 200.0 mL = 0.200 L
Molarity of the hydrochloric acid = 0.089 M
of HCL

According to reaction, 1 mole of HCl is neutralized by 1 mole of sodium bicarbonate.
Then 0.0178 moles of HCl wil be neutralized by :
of sodium bicarbonate
Mass of 0.0178 moles of sodium bicarbonate:
0.0178 mol × 72 g/mol = 1.4952 g
1.4952 grams of sodium bicarbonate she would need to ingest to neutralize this much HCl.
Density = mass divided by volume
Density = 8.2 divided by 24.5
Density = 0.33g/cm3
A valence bond is something used to explain chemical bonding. And as well a molecular orbital. So Two atoms that have unpaired electrons in their orbitals that overlap rises to give a chemical bond. So basically. The two atoms give each other's unpaired electron to form a filled orbital to make a hybrid orbital and for it to bond together.
