Answer: Option B
Explanation: when strong acid react with strong base, the resulting solution is neutral as in the case of HCl and NaOH
HCl + NaOH —> NaCl + H2O
From the equation obtained, The salt ( NaCl) obtained is a normal salt which is neutral.

Answer:
Manganese(II) sulfide
Explanation:
is a chemical compound of manganese and sulfur. It occurs in nature as the mineral alabandite (isometric), rambergite (hexagonal), and recently found browneite (isometric, with sphalerite-type structure, extremely rare, known only from a meteorite).
Answer:
C) differ in the arrangement of their atoms about a double bond
Explanation:
Cis-trans isomers -
Isomers are the molecules which have the same molecular formula but they differ in their arrangement of atoms.
The two isomers possible are the cis and the trans isomer .
1. Cis - isomer - The priority group or the similar group are at same side of the double bond .
2. trans - isomer - The priority group or the similar group are at different side of the double bond . ( the group are diagonally present )
Hence , the option about cis - trans isomer is ( c ) .
