Reacción: H2 + CSe2 → CH4 + H2Se a)Escribir la ecuación química balanceada.
b)Realiza la estructura de Lewis de todos los reactivos y productos de la reacción.
c)Para aquellas moléculas que tengan un átomo central determinar la geometría molecular.

when [oh-] is 10-5  m, and [h3o+] is 10-9  m, the poh is 5 and ph is 9. again in both cases the sum of ph and poh is 14. however, the hydrogen ion concentration is not always going to be equal to exactly 1 x 10 raised to a negative number. for example, we skipped over the value of 2.0 x 10-7.

the maximum mass of nh3 is nh3 in grams

i think its 100.

hope this !
