The given 2.6 µC of charge is due to a buildup of electrons, each of which has a charge of 1.6 x 10^-19 C. The 2.6 <span>µC is equivalent to 2.6 x 10^-6 C, so we can divide this by the individual charge of an electron:
</span>2.6 x 10^-6 C / 1.6 x 10^-19 (C/electron) = 1.625 x 10^13 electrons
6) Na2 SO4
7)nonmetallic elements

* sorry I didn't know Q. 8/9
Cells and microorganisms are extremely complex
Reactants are the substances that undergo changes and the new substance created from it is called products.
