What is the name of a solution whose concentration of solute is equal to the maximum concentration that is predicted from the so
faltersainse [42]

<u>Answer:</u> The correct answer is saturated solution.

<u>Explanation:</u>

For the given options:

Dilute solutions are defined as the solutions in which solute particles are present in less very amount than the solvent particles.

Unsaturated solutions are defined as the solutions where more and more of solute particles can be dissolved in the given amount of solvent.

Saturated solutions are defined as the solutions where no more solute particles can be dissolved in the solvent.  The concentration of the solute particles that can be dissolved in a solution is maximum.

Supersaturated solutions are defined as the solutions where more amount of solute particles are present than the solvent particles.

From the above information, we conclude that the given solution is saturated solution.

Is there a way to stop radioactive decay?
Wittaler [7]
The chain reaction is easy to stop. Just add a neuron absorbing material. The Control Rods in rectors can do that You just SCRAM (put the rods all the way in) or add something like Boron and the chain reaction stops. 

<span>The problem is the radioactive waste. Those isotopes break down and release heat spontaneously, no neutrons required. The only known way to stop or slow radioactive decay down is to slow time down by moving at relativistic speed or near orbit to a black hole.</span>

Calculate the wavelength in nm of ultraviolet light with frequency of 5.5 x 10¹⁵ Hz.
snow_tiger [21]

Answer: Wavelength of ultraviolet light is 54 nm.

Explanation:

Electromagnetic wave is defined as the wave which is associated with both electrical and magnetic component associated with them. They can travel in vacuum as well and travel with the speed of light.

The relationship between wavelength and frequency of the wave follows the equation:

\nu=\frac{c}{\lambda}

where,

\nu = frequency of the wave  =5.5\times 10^{15}Hz

c = speed of light  =3\times 10^8ms^{-1}

\lambda = wavelength of the wave  

Putting in the values we get:

5.5\times 10^{15}s^{-1}=\frac{3\times 10^8ms^{-1}}{\lambda}

\lambda=0.54\times 10^{-7}m

1nm=10^{-9}m

\lambda=54nm

Thus wavelength of ultraviolet light is 54 nm.
