Necesito saber sus IMECAS hacer los valores para todas las zonas y los 3 horario, poner las operaciones Calcula los puntos IMECAS para cada zona y en cada hora. Recuerda que 0.11 ppm de O3 equivales a 100 IMECAS, por ejemplo:
Convertir 0.0358 ppm de O3 a puntos IMECAS

0.0358ppm de O3 x 100 IMECAS = 35 IMECAS
0.11PPM O3

They are all decomposition reactions.

Radon-222 or rn-222 has a half-life of 3.82 days. to determine the fraction of an original sample of rn-222 that remains unchanged after 7.646 days, we calculate the amount of rn-222 remaining after 7.646 days and divide it with the original amount. using 1 gram as a basis and using half-life calculation methods, we can determine that  0.249 or 0.25  grams of rn-222 will remain, and thus the fraction remaining is 0.25 or 1/4.
