11. ionic charge +1, helium.
12. ionic charge 2-, neon.
13. ionic charge 3+, neon.
Answer:
The coefficient is 1
Explanation:
CaO(s) + CO2(g) -> CaCO3(s)
In the balanced equation, the coefficient for CaO is 1
The coefficient represents the number of moles of a compound in the stoichiometry of the reaction
Answer: Use the titration formula
Explanation:
Dipole Dipole Forces. LDFs are too weak to remain as liquids at room temperature, making them gases. DDFs are the only possible choice.
