Answer:
Nonmetals are further to the right on the periodic table, and have high ionization energies and high electron affinities, so they gain electrons relatively easily, and lose them with difficulty.
Explanation:
They also have a larger number of valence electrons, and are already close to having a complete octet of eight electrons.
Answer:
It is getting thicker and keeping the Earth warmer.
Answer:
3 hydrogen ions
Explanation:
phosphate ion is (PO4)^-3. It has charge -3.
Hydrogen ion has charge +1.
So, we need 3 hydrogen ions,
3H^(+1) + PO4(-3) ---> H3PO4
A heterogenous mixture is one which does not have uniform properties throughout. This is likely to happen in a mixture of sand and water because sand does not dissolve in matter and will settle down.
