Molar mass SiO2 = 28 + 32 = 60
<span>so moles sand = 3.4 x 10-7 / 60</span>
C) volume
.........
The volume of gas depends on e.g. temperature and pressure.
(2) Mg, Ca, and Ba have the most similar chemical properties, and we know this because of their coexistence in the group alkali earth metals (group 2) on the periodic table.
Explain, in terms
of both atoms and molecular structure, why there is no isomer of CH3OH.
There is no isomer of CH3OH or methanol because it
contains only one carbon atom. And also, the structure is tetrahedral, having
four substances attached to the carbon atom.
