True, cracking distillation is one process used to break hydrocarbons into smaller and more useful parts. This is achieved by using high temperatures and pressures with a catalyst. The most common catalyst used are the zeolites.
D. Steam enters a cylinder and pushes a piston
The answer is c because five plus two is seven and take away that is 4
The molar mass of vanadinite is 1416.27 g/mol. Looking at
the molecular formula we can see that there is 1 mole of Cl for every mole of
vanadinite. Therefore:
mass percent = [(1 mole Cl * 35.45 g/mol) / (1 mole
Pb5(VO4)3Cl * 1416.27 g/mol)] * 100%
<span>mass percent = 2.50%</span>
