Answer:
False
Explanation:
The displacement method is not used to find the volume of irregularly shaped objects. Rather the opposite.
According to the reaction equation:
Ba(OH)2 ↔ Ba2+ + 2OH-
when 0.015 M 0.015M 2*0.015M
∴ [OH-] = 0.03 m
so we can get the POH = - ㏒ [OH-]
by substitution:
∴ POH = -㏒ 0.03
= 1.52
and then we can get the PH from this formula:
PH + POH = 14
so by substitution:
∴PH = 14 - 1.52
≈ 12.48
Answer:
A single replacement reaction.
Explanation:
AB + C ---> CB + A
A single replacement reaction.
One of the common indicators that a chemical reaction has occurred is if the react ants reacting produce a precipitate that is insoluble within the solution and forms.
