Answer:
(a) ![BaCl_2(aq)+Na_2SO_4(aq)\rightarrow BaSO_4(s)+2NaCl(aq)](https://tex.z-dn.net/?f=BaCl_2%28aq%29%2BNa_2SO_4%28aq%29%5Crightarrow%20BaSO_4%28s%29%2B2NaCl%28aq%29)
(b) The particles of the formed barium sulfate remain suspended in the aqueous media forming a colloid.
Explanation:
Hello,
In this case, when solutions of barium chloride and sodium sulfate are mixed, the following chemical reaction is carried out:
![BaCl_2(aq)+Na_2SO_4(aq)\rightarrow BaSO_4(s)+2NaCl(aq)](https://tex.z-dn.net/?f=BaCl_2%28aq%29%2BNa_2SO_4%28aq%29%5Crightarrow%20BaSO_4%28s%29%2B2NaCl%28aq%29)
Thus, we can notice that the product barium sulfate remains solid since its solubility in aqueous media is very low, for that reason at the beginning the solution becomes cloudy as its particles remain suspended in the water forming a colloid. Nevertheless, after some days, the suspended particles get precipitated by the effect of the gravity, therefore, we observe the solid on the bottom of the beaker.
Regards.

Answer:
Geothermal power plants, which use heat from deep inside the Earth to generate steam to make electricity. Geothermal heat pumps, which tap into heat close to the Earth's surface to heat water or provide heat for buildings
Explanation:
Sugar dissolving in warm water is an example of physical change.
physical change is doesn't alter the composition or the identity of the substance .
That's mean when you dissolves sugar in water, after a while the object will be the same which mean that the component doesn't change
Density is the mass of compound divided by its volume can be shown as follows:
![d = 0.5 g /mL = m /V = m /40 = 0.5](https://tex.z-dn.net/?f=d%20%3D%200.5%20g%20%2FmL%20%3D%20m%20%2FV%20%3D%20m%20%2F40%20%3D%200.5)
![m = 20 g](https://tex.z-dn.net/?f=m%20%3D%2020%20g)
40 mL of snow having 20 g of mass calculated from density.
Now, 10 cm of snow = 3.93 inches = 20 g
As, 10 inches of rain will produce 11 inches of ice as the volume of ice is bigger than rain water.
10 inches rain = 11 inches snow
3.93 inches of snow produced by
![= (3.93 * 10) /11 = 3.57 inches rain.](https://tex.z-dn.net/?f=%3D%20%283.93%20%2A%2010%29%20%2F11%20%3D%203.57%20inches%20rain.)
Thus, 3.57 incehs of rain produces by 10 cm snow.
