De?ne reduction potential and oxidation potential.
Reduction potential of a metal is the measure of tendency of a metallic electrode to gain electrons when it is in contact with a solution of its own salt of unit molar concentration at 25C. Subsequently, the tendency of an electrode to lose electrons and to get oxidized, when it is in contact with its own salt solution of unit molar concentration at 25 C is called as oxidation potential.
Sample of ethane gas (molar mass & 30.1 g/mol) occupies 1.2 x 10 -2 m3 at 46°C and 2.4 x 105 Pa. How many moles of ethane are present in the sample? What is the mass of the
a) The molar mass of air is 28.97 kg/kmol and the universal gas constant is 8.314 kJ/(kmolK). Show by calculation that the particular gas constant of air is around 0.287 kJ/(kgK)
Newton's Law of Gravitation In 1687, Newton did not "discover" gravity but he did figure out that gravity is universal. It makes a ball fall when you drop it on earth. It also
For the circuit shown in Figure , verify the value of V1. If the total circuit resistance is 36Ω. Determine the supply current and the value of resistors R 1 , R 2 and R 3
When a physical property such as charge exists in discrete "packets" rather than in continuous amounts, the property is said to be: a) Discontinuous b) Abrupt c)
what different is between photons? Answer; the difference between photons depends to their frequency, and frequency depends to the number of CPH in structure of photon. Thus
Explain the presence of unmodified radiation in Compton scattering.
So I have a question here and I am totally lost: A car starts from rest and accelerates at a constant rate of 1.1 m/s2. If the radius of the car wheels is 29.0 cm, and the final an
Q. Give the applications of Moseley's law. (i) The elements are organized in the periodic table according to the atomic numbers and not according to the atomic weights. (ii
