All three of them i know i already did that
Answer:
C boron, germanium, arsenic, silicon
Sodium would form Na+
Oxygen would form O-2
Phosphorus would form -3 or +5
Sodium and oxygen would combine to form ionic bonds because one is a metal and the other is non-metal, while Phosporus and oxygen would combine to form covalent bonds because they are both non-metals.
Answer:
a) acidic; [H+] = 10^-2.5 = 3 x 10^-3
b) basic; [H+] = 10^-11.7 = 2 x 10^-12
c) slightly acidic (almost neutral); [H+] = 10^-6.8 = 1.6 x 10^-7
d) acidic; [H+] = 10^-3.31 = 4.9 x 10^-4
Explanation:
pH < 7 is acidic; pH > 7 is basic; pH = 7 is neutral
[H+] = 10^-pH
Answer:
B
Explanation:
It said there "share electrons" so the two atoms should be non-metals
