Answer:it's called unsaturated solution, because that's it's definition
Nylon is a polymer because it is made of a lo of molecules bonded together.
Answer:
NOCl structure has geometry of trigonal planar and N has sp2 hybridisation. N is the central atom because it is less electronegative than O atom and Cl cannot be the central atom because it only forms a single bond. So, the central atom of NOCl is N and its hybridisation
Please have more information. Thanks
Answer: The molarity of a solution made by dissolving 12.6 grams of NaNO3 to make 200 ml of solution is 0.74 M
Explanation:
Molarity is defined as the number of moles of solute dissolved perliter of the solution.

where,
n= moles of solute
= volume of solution in ml = 1000 ml

Now put all the given values in the formula of molarity, we get

Thus the molarity of a solution made by dissolving 12.6 grams of NaNO3 to make 200 ml of solution is 0.74 M
