pyramidal, if you have a molecule kit, i would strongly recommend watching a video of someone using a kit explaining the different shapes and following along. It helps a lot!
Answer:
The answer to 12 is Indium... you should be able to figure out the rest from there with help from the internet since i've given you the element
Explanation:
I would usually do it but I got a ton of hw

Answer:
Ca^2+
Explanation:
As we know, more energy is required to remove an electron from a positively charged ion than is required to remove an electron from a neutral atom. Hence, the second ionization energy of calcium is greater than its first ionization energy.
However, the third and fourth ionization energies of calcium are much higher than the second ionization energy because they involve removal of electrons from an inner filed shell. This process requires a lot of energy and is often not feasible.
Hence, the most common ion of calcium must be Ca^2+ where only two electrons are removed from calcium.
Answer:
a) solubility increases
b) solubility decreases
c) solubility increases
Explanation:
I) Fe^3+(aq) + 3Br^- --------> FeBr3 (aq) solubility increases
II) Fe^3+(aq) + 3OH^- ---------> Fe(OH)3(s) solubility decreases
III) Fe^3+(aq) + 6CN^- -----------> [Fe(CN)6]^3- (aq) solubility increases
The ionic equations shown above shows the possible changes in solubility when Fe(OH)3 is added to each of the solutions mentioned in the question.
