What is the overall reaction order for this rate law rate equals kA2BC

The overall reaction order for k[A]^2[B][C] would be 4

Because [A] has a rate order of 2

[B] has a rate order of 1

[C] has a rate order of 1

And when you add them together...

2 + 1 + 1

You obtain four

What forces hold network solids together

All chemical bonds, including those found in network solids, derive from the electromagnetic force. Positively charged protons attract negatively charged electrons. Although atoms start off with an equal number of protons and electrons, and are therefore electrically neutral, the electrons rearrange themselves in ways that create attractions between atoms. Covalent bonds
