Answer:
Not sure if you still need help, but here ya go. I'm not going to rewrite the chemical names, so this is the order of answers.
P2H6
NO3
KF
NO
N4H6
Explanation:
Just gotta break down the names and look at the roots. I'll walk through the first one.
ex) Diphosphorus hexahydride:
Di means two, and Phosphorus means just that, phosphorus. So we have two phosphorus, represented by P on the periodic table. So, P2
Hexa means 6, and hydride means hydrogen. We know this because we take the part of the word before 'ide' to get hydr, the first part of hydrogen.
Thus, we have six hydrogen, represents by an H on the periodic table. So, H6
Put it together, we have P2H6
Just have to do that to all the other ones. Look at the prefix to get the number of atoms, then the suffix to know what the atom is. That being said, KNOW YOUR PREFIXES or this gets really hard.
note: metals, if compound is ionic, are always first in the name
