Explanation:
Ionic solids are defined as the solids in which atoms of opposite charge are held together by strong forces of attraction. As a result, in solid state these atoms are not present in free state.
Hence, they cannot move as ions from one place to another. On the other hand, metals are able to conduct electricity because of the presence of free electrons in it.
As we know that electricity is the flow of ions or electrons from one place to another. Therefore, metals are able to conduct electricity in their solid state.
V = 28,42 mL = 0,02 L
molar mass C3H6O = 58
n C3H6O
= V / 22,4
= 0,02 / 22,4
= 0,0009 mol
mass
= n x molar mass
= 0,0009 x 58
= 0,0522 gr
Answer:
C). Half-reactions with SRP values greater than zero are spontaneous.
Explanation:
SRPs or Standard Reduction Potentials are characterized as the ability of a probable distinction among the anode and cathode of a usual/standard cell. It aims to examine the capacity of chemicals to reduce themselves.
The third statement asserts <u>a true claim regarding the SRPs(Standard Reduction Potentials) that the 'half-reactions which take place with the SRP possesses the values higher than zero and they are unconstrained</u>.' The other statements are incorrect as they either show the estimation of SRPs more than 0 or display them as being restricted. Thus, <u>option C</u> is the correct answer.
