Noble gases show degrees of reactivity. These elements have generally complete electron shells. Noble Gases Include: Helium, Neon, Argon, Krypton, Xenon, Radon, Ununoctium. Reactive elements that form compounds known as halides.
It’s soluble in NaOH, NaH
Answer:
2Al + 3CuSO4 → Al2(SO4)3 + 3Cu
Explanation:
I THINK
Explanation:
The pH of the solution is 9.63 ± 0.03.
we know that
pH= -log[H+]
⇒[H+] =
= =
Now to find absolute error we use the formula
Absolute error/[H+] =ln10(uncertainity)
Absolute error = ln10×[H+] ×0.03
=
