Record the observations as shown below: Weight of the sinker in air = W 1 gf Weight of the sinker in water = W 2 gf Weight of the sinker in liquid = W 3 gf Loss of weight of the sinker in water = (W 1 - W 2 ) gf Loss of weight of the sinker in liquid = (..

Base Molecular formula Base Molecular formula Ammonium hydroxide NH 4 OH Aluminium hydroxide Al(OH) 3 Sodium hydroxide NaOH Zinc hydroxide Zn(OH) 2 Potassium hydroxide KOH Iron(II) hydroxide Fe(OH) 2 Calcium hydroxide CA(OH) 2..

i) Kinetic energy of a body moving with a velocity v << c. We know that Here, mc 2 is the total energy and m 0 c 2 is the rest mass energy. Therefore, (mc 2 - m 0 c 2 ) represents the kinetic energy. . This is the same result that we obtain b..

Introduction - Sodium belongs to Group I in the periodic table. This group is otherwise known as the alkali metals group. Since the atomic number of sodium is 11, its electronic configuration is 2,8,1. Sodium easily loses the lone electron to attain the stable configuration of neon. There..

The measurement of dipole moment helps in distinguishing between polar and non-polar molecules. Non-polar molecules have zero dipole moment while polar molecules have some value of dipole moment. For example: Non-polar molecules: O 2 , Cl 2 , BF 3 , CH 4 Polar Molecules: HF ..
