It happens through precipitation when water evaporates from the suns rays and rises into the atmosphere

It goes from lakes and as the temp rises, it evaporates into clouds. from there, the clouds get heavy, and it produces rain, and the rain forms rivers and then back into lakes.

Determine which compound would raise the boiling point of water the most

umka2103 [35]

Because all the compounds are at the same concentration, the one that can produce more particles in solution will be the one that will raise the boiling point the most.

Another name for light is

Karo-lina-s [1.5K]

Answer:

Another name for light is ¨Electromagnetic Radiation, luminous energy, and/or radiant energy.¨

Explanation:

Light is the electromagnetic radiation that´s capable of causing a visual sensation and has wavelengths from about 380 to about 780 nanometres. Electromagnetic radiation includes Radio Waves, Microwaves (used in microwaves), Infrared Radiation (heat), Visible Light (the colors we see), Ultraviolet (the UV radiation that causes sunburns), X-Rays (used in medical X-Rays), and Gamma Rays (which can be used to treat cancer). Light waves are transverse waves because they only travel east or west, but their crests and troughs face north and south (if desplayed on a coordinate grid). They wouldn´t be longitudinal waves because these waves don´t have vertical crests and troughs.

I hope this helps!

A solution contains an unknown mass of dissolved barium ions. When sodium sulfate is added to the solution, a white precipitate

AlladinOne [14]

The given question is incomplete. The complete question is as follows.

A solution contains an unknown mass of dissolved barium ions. When sodium sulfate is added to the solution, a white precipitate forms. The precipitate is filtered and dried and then found to have a mass of 212 mg. What mass of barium was in the original solution? (Assume that all of the barium was precipitated out of solution by the reaction.)

Explanation:

When $Ba^{2+}$ and $Na_{2}SO_{4}$ are added then white precipitate forms. And, reaction equation for this is as follows.

$Ba^{2+} + SO^{2-}_{4} \rightarrow BaSO_{4}$

It is given that mass (m) is 212 mg or 0.212 g (as 1 g = 1000 mg). Molecular weight of $BaSO_{4}$ is 233.43.

Now, we will calculate the number of moles as follows.

No. of moles = mass × M.W

= $\frac{0.212}{233.43}$

= 0.00091 mol of $BaSO_{4}$

Hence, it means that 0.00091 mol of $Ba^{2+}$ . Now, we will calculate the mass as follows.

Mass = moles × MW

= $0.00091 \times 137.327$

= 0.124 grams or 124 mg of barium

Thus, we can conclude that mass of barium into the original solution is 124 mg.
