<em>Nothing happens</em>; water is still H₂O, even if it turns into ice, or vapor. Although, the molecules still move around faster, just like a normal gas would.
Answer:
218.09g
Explanation:
the formula for density is mass/volume
you have volume so rlly what you have is 19.3g/cm3=m/11.3cm3
so mass equals density x volume
and 19.3 x 11.3 = 218.09
B, more kinetic energy means more collisions and thus more reactions according to collision theory.
Expression for the Balmer series to find the wavelength of the spectral line is as follows:
1 / λ = R

Where, λ is wavelength, R is Rydberg constant, and n is integral value (4 here → Fourth level)
Substitute 1.097 x 10⁷ m⁻¹ for R and 4 for n in the above equation
1 / λ = (1.097 x 10⁷ m⁻¹)
= 0.20568 x 10⁷ m⁻¹
λ = 4.86 x 10⁻⁷ m
since 1 m = 10⁹ nm
λ = 486 nm
Energy and mass equivalence
Explanation:
The law of conservation of energy does not apply to nuclear reactions, the law of conservation of mass-energy makes more sense in this regard.
In nuclear reactions mass is transformed into energy. Therefore, it does not conform with the law of conservation of energy.
- According to the law of conservation of energy "energy is neither created no destroyed but they are transformed from one form to another. "
- In nuclear reactions, mass is usually lost. Mass is not conserved.
- But, the mass is converted into energy and we say there is mass and energy equivalence for nuclear reactions.
