Bohr’s Model:· Electrons revolve around the nucleus in fixed orbits (energy levels).· Energy is absorbed/emitted when ele...
Energy can neither be created nor destroyed, only transformed. ΔU=q+w
At constant temperature, pressure is inversely proportional to volume. P∝1/V
O=C=O (Each O shares 2 electrons with C)
Because they have completely filled valence shells and are already stable.
The repetition of properties of elements after regular intervals when arranged in increasing order of atomic number.
It is impossible to simultaneously determine the exact position and momentum of a particle. Mathematically: Δx⋅Δp≥h/4π
Molar mass of CO₂ = 12 + 2×16 = 44 g/mol Moles = 88 / 44 = 2 moles
· Mole: Amount of substance that contains as many entities as there are atoms in 12 g of carbon-12. · Avogadro's numb...
The centre of mass (C.M.) can be defined as a point where the mass of a body is supposed to be concentrated.For the above listed geometric shapes having a uniform mass density, the centre of mass lies at their respec...
