A solid is added to a liquid in a flask.
Dmitry [639]

Answer:

C. the solid dissolves after it is added to the liquid

Explanation:

Why, you may ask?  Because endothermic reactions absorb energy by undergoing change. And that solid, just absorbed energy.

When something melts, the molecules inside the substance receive more and more energy, until the substance's molecules have enough energy to vibrate and wiggle past each other, breaking their structure. if the solid is receiving more energy from its surroundings, aka the liquid, the reaction is in fact absorbing energy. And if a reaction is absorbing energy, it's an endothermic reaction.

What is the frequency of a wave of intrared light which has a wavelength of 4.35 * 10 ^ - 5 meters?
weqwewe [10]

Answer

6.9 x 10¹²Hz

Explanation:

Given parameters:

Wavelength of the wave  = 4.35 x 10⁻⁵m

Unknown:

Frequency of the wave = ?

Solution:

The speed of a wave is related to the wavelength and frequency using the expression below;

          C  = Fλ

C is the speed of light = 3 x 10⁸m/s

F is the frequency

λ  is the wavelength

Insert the given parameters and solve;

      3 x 10⁸  = F x 4.35 x 10⁻⁵

         F  = \frac{3 x 10^{8} }{4.35 x 10^{-5} }   = 6.9 x 10¹²Hz
