Answer:
It will turn red
Explanation:
Bases will turn the litmus paper (impregnated with an acid-base indicator) blue.
Acids will turn turn the litmus paper (impregnated with an acid-base indicator) red.
Since the produced HCl is a strong acid, the litmus paper will turn red, when touching the HCl.
The red shows the presence of an acid, in this case HCl.

In the lewis structure we have 24 valence electrons
This is what a proper adjective is.
The *independent* variable is the one that you always can control. However, the dependent variables are not since they **depend** on another.
Answer:
The diameter of the oil molecule is
.
Explanation:
Mass of the oil drop = 
Density of the oil drop = 
Volume of the oil drop: v


Thickness of the oil drop is 1 molecule thick.So, let the thickness of the drop or diameter of the molecule be x.
Radius of the oil drop on the water surface,r = 41.8 cm = 0.418 m
1 cm = 0.01 m
Surface of the sphere is given as: a = 

Volume of the oil drop = v = Area × thickness


The thickness of the oil drop is
and so is the diameter of the molecule.
