When Lead (II) acetate and Hydrogen sulfide react, they form Lead sulfide and Acetic acid. The reaction is a reduction-oxidation (redox) reaction.
The balanced chemical reaction is this:
Pb(C2H3O2)2 + H2S --> PbS + 2C2H4O2
And the net ionic reaction is this:
Pb2+ + S2- --> PbS

The decomposition of hydrogen peroxide follows first order kinetics and has a rate constant of 2.54 x 10-4 s-1 at a certain temp
Eva8 [605]

Answer:

[A]_0=0.400M

Explanation:

Hello.

In this case, since the first-order reaction is said to be linearly related to the rate of reaction:

r=-k[A]

Whereas [A] is the concentration of hydrogen peroxide, when writing it as a differential equation we have:

\frac{d[A]}{dt} =-k[A]

Which integrated is:

ln(\frac{[A]}{[A]_0} )=-kt

And we can calculate the initial concentration of the hydrogen peroxide as follows:

[A]_0=\frac{[A]}{exp(-kt)}

Thus, for the given data, we obtain:

[A]_0=\frac{0.321M}{exp(-2.54x10^{-4}s^{-1}*855s)}

[A]_0=0.400M

Best regards!

The maximum efficiency possible in an energy conversion process that is not limited by the second law of thermodynamics
Anna [14]

Answer:

100 %

Explanation:

The maximun efficiency possible (whem not limited by the  second law of thermodynamics) happens when all the energy used is transformed into the type of energy we required with no other transformations.

For example, in an engine we want that all the energy we supply is being converted to work. That's the ideal case, but in reality always some of that energy is lost in the form of heat.
