Answer:
2.14 x 10^-10 M
Explanation:
[H+] = 10^(-pH) = 10^-9.67 = 2.14 x 10^-10 M
Answer:
Linear molecule with two domains
Explanation:
Answer:
Ni^2+(aq) + CO3^2-(aq) -----> NiCO3(s)
Explanation:
First let us put down the molecular equation of the reaction
Na2CO3(aq) + Ni(NO3)2(aq)----> 2NaNO3(aq) +NiCO3(s)
Hence ionically, we will have the reaction as;
Ni^2+(aq) + CO3^2-(aq) -----> NiCO3(s)
The ionic equation usually indicate the ions that actually take part in the reaction. They often lead to the formation of the solid product or precipitate.
The order ions that are no shown in the ionic reaction equation are called spectator ions.
Hence, the reaction shown in the answer is the ionic reaction equation for the mixing of nickel II nitrate and sodium carbonate.

Explanation:
Ionic compounds are the compounds in which complete transfer of electrons takes place from one element to another. In these compounds, the forces of attraction between the particles is strong and hence, they have the highest boiling points.
