4H202->2H2O+O2
Hope this helps mate good luck on whatever ur doing
Scandium forms one ion, Sc3+, with an electron configuration of 1s2 2s2 2p6 3s2 3p6
C) Lower,
They're lower because molecular solids form IMF's such as Dipole-Dipole and H-Bonds, while Ionic bonds are much more powerful.
In this kind of exercises, you should use the "ideal gas" rules: PV = nRT
P should be in Pascal:
445mmHg = 59328Pa
1225mmHg = 163319Pa
V should be in cubic meter:
16L = 0.016 m3
R =

= constant

=

==> P1 * V1 = P2 * V2
V2 =

=
V2 = 0.00581 m3 = 5.81 L
