Identify the correct net ionic equation for the reaction that occurs when solutions of Pb(NO3)2 and NH4Cl are mixed.
1 answer:
Answer:
Pb2+(aq) + 2Cl–(aq) ----> PbCl2(s)
Explanation:
The net ionic equation shows the main reaction that takes place in a system. Hence, a net ionic equation focusses only on those species that actually participate in the reaction.
For the reaction between Pb(NO3)2 and NH4Cl , the net ionic equation is;
Pb^+(aq) + 2Cl^-(aq) ---> PbCl2(s)

The true statement is (A) energy is absorbed during the reaction
Answer:
It will be halve of T
Explanation:
V1 = V
T1 = T
V2 = ½V
T2 = x
V1/T1 = V2/T2
V/T = ½V/x
Vx = ½VT
2Vx = VT
2x = T
x = ½T
Answer:
Na
Explanation:
because sodium has 1 electrons so it loses it to be stable and so have positive charge of 1
Use PV =nRT
