The photoelectric effect occurs when are emitted from metal when the metal is struck by light of certain frequencies.

electrons

Explanation:

The photoelectric effect occurs when electrons are emitted from metal when the metal is struck by light of certain frequencies.

Some of the applications of this effect include photomultipliers (which are a key component in spectroscopy instruments) and night vision devices.

B: It converts light into electric current.

Explanation:

B: It converts light into electric current.

Explanation:

Answer:

Step-by-step explanation:

It is clear by the equation 2(27+3×35.5)= 267 gm of AlCl3 reacts with 6× 80 = 480 gm of Br2 . So 29.2 gm reacts = 480× 29.2/267= 52.6 gm

Calcium (Ca)(On the periodic table, ionization energy increases as you go up and to the right of the periodic table)

glycoproteins

Explanation:

A positive reaction for Molisch's test is given by almost all carbohydrates (exceptions include tetroses & trioses). It can be noted that even some glycoproteins and nucleic acids give positive results for this test (since they tend to undergo hydrolysis when exposed to strong mineral acids and form monosaccharides).
