Answer:
An atom that gains a negative electron, it becomes a negative ion. If it loses an electron it becomes a positive ion. Picture 1.8 Some atoms lose electrons and become positive ions. Others gain electrons and become negative ions.
Explanation:
...
Ka for weak acids is ---> Ka= (X)²/ (initial- X)
initial= 0.0400 M
to find X, you can find the H concentration using pH
[H+]= 10^-pH
[H+]= 10^-1.80= 0.016 which is X
ka = (0.016)²/ (0.0400 - 0.016) = 0.011
Answer:
Moles of zinc chloride produced are 0.09942 moles.
Explanation:
Mass of zinc used = 6.5 g
Moles of zinc =
According to reaction, 1 mol of zinc gives 1 mole of zinc chloride,then 0.09942 moles of zinc will give :
of zinc chloride
Moles of zinc chloride produced are 0.09942 moles.
the answer would be B. temperature
