How many moles of Pb(NO3)2 are required
if 8 moles of AICI3 are consumed?

3Pb(NO3)2 + 2AlCL3 —> 3PbCl2 + 2Al(NO3)3

one state would change   like louisiana to texas. thats a change

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.

the temperature of the gas, in k, not celsius.
