speed of light=wavelength*frequency

3*10^8m/s=wavelength*1.20*10^13

wavelength=3*10^8/1.2*10^13

=10^-5/0.4=2.5*10^-5m

While washing his hands before the client consultation with Chloe, Jayden dropped some water onto the countertop. When he came b
Anastaziya [24]

Answer:

The water molecules turned into gas called<em> "water vapor"</em> and are now part of the air.

Explanation:

The "drops of water" are actually made up of<u> water molecules.</u> Under <em>heat,</em> they change their phase from liquid to gas. This means that the water molecules <em>move faster. </em>Such movement allows the molecules to escape into the atmosphere as gas. Such gaseous state of water is called "water vapor" <em>(transparent in color).</em>

The client consultation must have taken time that the drops of water evaporated when Jayden came back.

Aside from evaporation, water vapor may also be produced through the process called "sublimation." This happens when<em> ice directly turns into gas without becoming a liquid.</em>

So, this explains the answer.

What is the molar concentration (molarity) of a solution made by dissolving 0.285 moles of CaCl2(s) in just enough water to form
marusya05 [52]

Answer:

The answer to your question is Molarity = 0.238

Explanation:

Data

Molarity = ?

number of moles = 0.285

volume = 1.2 L

Molarity is a unit of concentration that relates the moles of a substance by the volume in liters.

Formula

Molarity = moles / volume

Substitution

Molarity = 0.285 / 1.2

Simplification and result

Molarity = 0.238

The rate of disappearance of hbr in the gas phase reaction 2hbr(g)?h2(g)+br2(g) is 0.160 m s-1 at 150°c. the rate of appearance
luda_lava [24]
The reaction rates of the substances whether disappearance of a reactant or the appearance of a product are related to each other by the chemical reaction. The reaction rates are related as follows:

rate = rHBr / 2 = rBr2 = rH2

rH2 = 0.160 / 2 = 0.08 M/s
