180 K
V1/T1 = V2/T2
V1 = 500 mL
T1 = 300 K
V2 = 300 mL
Solve the equation for T2 —> T2 = V2T1/V1
T2 = (300 mL)(300 K) / (500 mL) = 180 K
Answer : The correct option is, (1) 0
Explanation :
Oxidation state or oxidation number : It represent the number of electrons lost or gained by the atoms of an element in a compound.
Oxidation numbers are generally written with sign (+ and -) first and then the magnitude.
When the atoms are present in their elemental state then the oxidation number will be zero.
As per question, 'Mn' atom is a free element that means it is present in their elemental state then the oxidation state will be zero.
Hence, the correct option is, (1) 0
Answer:
4: Hydro electrical energy
5:Flase the law of conservation of energy is not violated by transformer.
Explanation:
4:Hydroelectric energy, also called hydroelectric power or hydroelectricity, is a form of energy that harnesses the power of water in motion—such as water flowing over a waterfall—to generate electricity. People have used this force for millennia.
5:Quantum Physics and Law of Conservation of Energy.
Niels Bohr, Hans Kramers, and John Slater proposed that these electrons violated the law of conservation of Energy momentarily. They stated that with each jump, energy is either created or destroyed by the electrons during the whole process.
