10.0 g C2H2 x 1 mol CH2 x 1 mol CaC) = .384 mol CaCy 1 mol C2H2
А
3. What conversion factor belongs in the box marked A if you are trying to
determine the number of moles of CaC, needed to prepare 10.0 g C, H,? CaC, +
2H,0 → 12H2 + Ca(OH)2
O 1 mol Caca
26.049 C, H,
O 1 mol CH
10g Ca(OH)2

it is a good conductor

explanation:

the ozone layer acts as a filter for the shorter wavelength and highly hazardous ultraviolet radiation (uvr) from the sun, protecting life on earth from its potentially harmful effects. when the sky is clear, there is an inverse relationship between stratospheric ozone and solar uvr measured at the earth's surface.
