Answer:
Destruction of rocks at convergent boundaries
Explanation:
Duuuuuuuuude. Dude.
Let's think for a sec, because this confused me.
Acid rain is chemical weathering. It has acid in it, so it weathers rocks. (Ewwww.)
Frost wedging is a major duh, because frost can weather rocks.
Oxidation reactions are a yes yes because it becomes oxidized.
When carbon bonds with 4 hydrogen atoms which is methane having sp3 structure so it is tetrahedral. electricity is conducted by electrons so graphite conducts by free and delocalised sea of electrons.
A reaction where one becomes two
2H202 --> 2H2O + O2
Lar mass of Ca<span> = 40.08 </span>grams/mole 77.4 g Ca<span> * ( 1 </span>mole Ca<span>/ 40.08 ... n = m / M 1mol </span>Ca<span>weights 40 gmol-1 n = 77,4 / 40 = 1.93 </span>mol<span>.</span>
