OK i didnt notice that. thanks for correction

typing error solution manual state that 760=0.5kX²+760X

I suppose spring compression to be X when jumpping from 1m. Therefore gravational potential mgh=760(1+X) and my cal:760(1+X)=0.5kX² why the solution manual state that 760=0.5kX²+760X

TKS for reply why the energy of work cannot converted to the energy of heat?

why does not contain heat transfer? please educate me.

Question: Solution manual: Is the solution manual correct or not? why does not contain heat transfer?

According to textbook, what you said is true but I still have to tackle the exam...please educate me why its oxidation number is 3 for all cobalts

question fig: solution manual: my solution: oxidation state of central cobalt is +6 due to 6 oxygen surrounding it,The other cobalt is +2 due to 2 oxygen surrounding it with NH3 ligand which is no count for oxidation state.

Being surprised with tour detailed inteprenetion TKS

question solved TKS

Q: Is it true that the value of K depends on the amounts of reactants and products mixed together initially? Explain. A:NO, Equilibrium and rates of reaction (kinetics) are independent of each other. A reaction with a large equilibrium constant value may be a fast reaction or a slow reaction...

TKS i get it

my question is in fig.
