All three of them i know i already did that
No
Magnesium Chloride is MgCl2
The method I use to name ionic compounds is 'swap and drop'
Mg oxidation number is +2 and Cl oxidation number is -1
Mg^2+ Cl^-1
'swap'
Mg^1 Cl^2
'drop'
MgCl2
When you add a pinch of baking soda into vinegar, carbon dioxide gas is produced
CaCl2(aq) + K2CO3(aq) → 2 KCl(aq) + CaCO3(aq)

Hope it helps :)
Answer:
+1
Explanation:
The electrical charge on protons are positive charges.
Protons are subatomic particles and they carry positive charges on them. In all instances, they are found in the tiny nucleus along with neutrons.
Both protons and neutrons contributes the bulk mass of an atom whereas electrons is negligible and inconsequential to the mass of the atom.
- Electrons carry negative charges within an atom with a charge of -1
- Neutrons are uncharged subatomic particles.
- Protons carry positive charges, +1
