Explain why the standard enthalpy of formation () for Cl2 (g) is zero, but its standard entropy is larger than zero.
Galina-37 [17]

The standard enthalpy of formation for chlorine is zero but the standard entropy is larger than 0 because it is the elemental state of chlorine.

The standard enthalpy of formation for chlorine is zero because cl2 is the elemental state of chlorine and it does not require any energy for the formation of the standard state of chlorine.

The entropy of any system cannot be negative. It can only be positive or zero.

The entropy of a system will become zero only at a absolute zero temperature.

That's why the entropy of chlorine in elemental state is more than zero because absolutely zero temperature can't be obtained.

Which statement describes the distribution of charge in an atom?
miv72 [106K]

The correct answer is:

A positively charged nucleus is surrounded by one or more negatively charged electrons

The explanation:

when:

proton is a positively charged elementary particle that is a fundamental constituent of all atomic nuclei.

neutron is a subatomic particle found in the nucleus of every atom except that of simple hydrogen. The particle derives its name from the fact that it has no electrical charge

electron is a negatively charged subatomic particle. It can be either free (not attached to any atom), or bound to the nucleus of an atom .  

so, , there are positively charged protons and zero-charged neutrons in the nucleus of an atom. Therefore, the nucleus is positively charged, Surrounding the nucleus, the electrons have negative charge. 

Thus, the correct answer is (3): A positively charged nucleus is surrounded by one or more negatively charged electrons is correct.

Why are these graphs misleading
ch4aika [34]
Although there isn’t a picture a graph can be misleading when it doesn’t start at zero, it doesn’t give accurate information, it skips too many numbers, the vertical scale is too big or too small. Hope this helps
