Calculate delta s ,delta s total when the volume of 123 g CO initially at 298K and 1 bar increased by a factor of four in (a) an adiabatic reversible expansion

0

Explanation:

we have ,

T = 298K temperature

P = 1.00 bar. pressure

M = 123g. mass CO

a) Adiabatic reversible expansion

q= 0. Heat is zero

we know the total entropy change is

ΔS total = Δs + Δs surrounding

ΔS surrounding = -q/ T

So, ΔS surrounding= 0

in reversible process,

ΔS= 0

Change in entropy should be positive for spontaneous process ΔS total ≥0

Therefore,

ΔS total= ΔS + ΔS surrounding

= 0

Hence, we can say that the process is not spontaneous, so the system and surrounding are in equilibrium.  

- calcium has greater affinity to bond with electron receptors than hydrogen does and hence, it has the ability to replace hydrogen in most of its compounds.

- lithium has 2 valence electrons in the product because it can make only 1 bond with hydrogen. beryllium has 4 valence electrons in the product because it can only make 2 bonds. it has fewer electrons than neon and can react with electron donors. each hydrogen has 2 valence electrons, the same as helium.

- the covalent bond formed between carbon and hydrogen is polar because carbon is more electronegative than hydrogen and it attracts the bonded electron pair closer to itself, thus giving hydrogen a partial positive charge.

- a hydrogen bond is a relatively weak bond that hydrogen atoms make with the electronegative atoms nitrogen, oxygen or fluorine.

so the best choice is a.) 2 calcium (ca) atoms

the correct answer would be b) volume versus temperature, because they are also directly proportional.
