Answer:

Liquid : A liquid has definite mass and it's volume does not change. It is hard to compress but flows easily. The shape of the liquid varies and depends on then shape of the container holding it.

Solid : A solid has a definite mass, definite shape and it's volume does not change. It does not flow and it is hard to compress.

Gas : A gas has a definite mass but it's volume can vary and it takes up the shape of container holding it. It flows easily and it is easy to compress.

Semiconductors are more effective than metals as converters of solar radiation into electricity because?

DedPeter [7]

Semiconductors show the property of both the conductor and insulator. They are more effective than metals as their valence electron can free flow by the sun's energy. Thus, option B is correct.

<h3>What are semiconductors?</h3>

Semiconductors are substances and materials that exhibit intermediate properties of conductors and insulators. They are solid materials that can conduct electrical charges due to the added impurity or change in temperature.

They have a valence electron in their outer shell that can absorb the energy from the sun to get excited. This leads to the flow of the charge in the semiconducting substance more easily.

Therefore, option B. the semiconductors can absorb the extra energy is correct.

Your question is incomplete, but most probably your full question was, Semiconductors are more effective than metals as converters of solar radiation into electricity because

A. it is easier for the atoms of a semiconductor to absorb solar energy and to move from place to place within the solid, thereby conducting electricity.

B. the energy contained in sunlight gives the valence electrons in the semiconductor atoms the extra energy they need to "flow" throughout the solid.

C. metals melt much too easily under direct sunlight and, as liquids, lose their ability to conduct electricity.

D. solar radiation has sufficient energy to knock electrons completely off the metal surface, making it impossible for the electrons to "flow" from atom to atom and conduct electricity.

"A solution with a total volume of 850.0 mL contains 43.5 g Mg(NO3)2. If you remove 25.0 mL of this solution and then dilute thi

ycow [4]

Answer: C = 0.014M

Explanation:

From n= m/M= CV

m =43.5 M= 148, V=850ml

43.5/148= C× 0.85

C= 0.35M

Applying dilution formula

C1V1=C2V2

C1= 0.35, V1= 25ml, C2=?, V2= 600ml

0.35× 25 = C2× 600

C2= 0.014M

a student uses universal pH paper to find the pH of three solutions . solution A has a pH of 5 solution B has a pH of 11 and sol

Andreas93 [3]

Universal pH paper turns red if it is very strongly acidic, turns orange if it is strongly acidic, turns yellow if it is weakly acidic, green if it is weakly alkali and blue if it is strongly alkali.

Solution A will turn orange as it is strongly acidic

Solution B will turn blue as it is strongly alkali

Solution C will turn yellowish green as it is neutral

(a) calculate the %ic of the interatomic bond for the intermetallic compound tial3. (b) on the basis of this result, what type o

Mrrafil [7]

Answer :

The correct answer is %IC = 10 % and bond is covalent bond with slight polarity.

<u>Percent Ionic Character :</u>

It is defined as percent of ionic character present in a polar covalent bond . The formula of % ionic character (%IC) is given as follows :

$Percent Ionic character = 1 - e^-^0^.^2^5 ^*^(^X^a^-^X^b^) * 100$
