All of the various light
waves move with the same speed, a value
<span>abbreviated (c) equal to 3.00
× 108 m/s. The frequency ([1]) that light waves
pass a given point is</span>
measured in waves/second or
simply ‘per second’ (1/s).
the frequency of the wave f =
(3.00 × 10^8 m/s)/ 2.340 m
<span>f = 1.28x10^8 Hz</span>
The substances largely ionic are:
NF3

<u>Answer:</u> The boiling point of solution is 101.56°C
<u>Explanation:</u>
Elevation in boiling point is defined as the difference in the boiling point of solution and boiling point of pure solution.
The equation used to calculate elevation in boiling point follows:

To calculate the elevation in boiling point, we use the equation:

Or,

where,
Boiling point of pure water = 100°C
i = Vant hoff factor = 1 (For non-electrolytes)
= molal boiling point elevation constant = 0.52°C/m.g
= Given mass of solute (urea) = 27.0 g
= Molar mass of solute (urea) = 60 g/mol
= Mass of solvent (water) = 150.0 g
Putting values in above equation, we get:

Hence, the boiling point of solution is 101.56°C
C burning
Because melting is incorrect lol
