Answer:
Using the graph, we can see that after 4.5 minutes, the bus traveled 4500 meters. Find 4.5 on the x axis, and then see what y value it corresponds to.
Let me know if this helps!
Correct Answer: option C:The pair which consist of molecules having the same geometry is CH2CCI2 and CH2CH2.
Reason:
Both of the above molecules contain double bonds. They are characterized by sp^2 hybridization. Also, they possess a trigonal planar geometry. In trigonal planar system, the molecule consist of three equally spaced sp^2 hybrid orbitals, which arranged at angle 120 degree.
Metallic sodium and chlorine gas are produced by the electrolysis of molten sodium chloride.
<h3>What is a word equation?</h3>
A word equation represents a chemical reaction using the names of the substances involved.
a) Word equation:
Sodium chloride + electrolysis → Sodium hydroxide + Hydrogen gas, Chlorine gas
b) The following reactions take place during the electrolysis of brine solution :
NaCl =
=
Now there are two cations and two anions which get discharged in the following way :
At cathode :
= 
At anode:
=
The remaining ions
= NaOH
That's why we get
,
and NaOH.
c) Balance each equation is:
2NaCl (l) → 2Na(s) +
(g)
