The correct answer is option C, that is, light from other galaxies is red. Shifted.

It has been witnessed by the astronomers that the light from the distant object in the cosmo is shifted towards the red color frequency that suggests that those objects are moving away or receding from the planet Earth. This process is called Redshift. A similar thing is witnessed for galaxies that are present at very distant places from the planet Earth.

Answer : The correct answer is option C.

Explanation:

Astronomers have observed that light from the distant object in the universe is shifted towards the frequency of red color which indicates that those object are receding or moving away from the planet earth.This phenomena was termed as Red shift .Same thing goes for galaxies which are very far away from the planet earth.

Where as if galaxies were moving towards the the planet earth their light would have shifted toward the frequency of blue color termed as blue shift.

Hence, the correct answer is option C.

aleksley [76]

Answer:

209.68

Explanation:

The only number that is relevant (though the rest are quite interesting) is the last one 1.98 * 10^24

1 mole of Barium Acetate Contains 6.02*10^23 particles.

There are 4 moles of carbon to every mole of Barium Acetate.

1.98 * 10^24 atoms / (4*6.02*10^23)

0.8223 moles of Ba(C2H3O2)2

Ba =                 137

4C = 4*12          48

6H = 6*1              6

4O = 4*16           64

1mole                 255 grams

0.8223 * 255 = 209.68 grams  

I have used rounded masses for these elements depending on the periodic table you use. Go through the question with your masses to get a more accurate answer. My answer will not differ by much. It is a guide.

Which of the following compounds will make an electrolytic solution?
Novosadov [1.4K]

Answer: KBr will make an electrolytic solution

Explanation:

Electrolyte is a substance which dissociates into ions when dissolved in water and thus is able to conduct electric current through them.

Compounds in solid form does not conduct electricity due to the absence of free ions.

a) SO_2 is a covalent compound and thus not an electrolyte.

b) C_2H_5OH  is a covalent compound and thus do not dissolve in water and thus is not an electrolyte.

c) KBr  is an ionic compound and thus dissolve in water and give ions which help to conduct electricity.

KBr\rightarrrow K^++Br^-

d) CCl_4  is a covalent compound and thus do not dissolve in water and thus is not an electrolyte.
