1. An organic compound is found to contain the
following constituents :
C = 33.8%. H = 4.7%., N - 13:2%, Cl= 33.4%
and rest is Oxygen. Determine its empirical mass?

Emperical formula

C₃H₅NClO

The empirical formula is the smallest comparison of atoms of compound =mole ratio of the components

The principle of determining empirical formula

mole ratio :

we divide by the smallest mole ratio (0.93)

C : H : N : Cl : O =

Emperical Formula :

the answer is yes

it has kinetic energy

reason

an object has kinetic energy when you stop the force carrying it, the object will stay in motion.

hope this contact me for more questions if you'd like: )

qualitative observation deals with data that can be observed with our senses: sight, smell, touch, taste, and hearing. they do not involve measurements or numbers. for instance, colors, shapes, and textures of objects are all qualitative observations.
