Answer:
Transition metals can have multiple oxidation states because of their electrons. The transition metals have several electrons with similar energies, so one or all of them can be removed, depending the circumstances. This results in different oxidation states. please mark me as brainellist
Answer:second law of thermodynamics
Explanation:the second law of thermodynamics states that the total entropy of an isolated system can never decrease over time and is constant if only if all processes are reversible.
Answer:
6.15.3 k
Explanation:
From the question we can see that
q = 0, Δu = w
Then,
![T_f = \frac{C_{V,m}+RP_{ext}P_i}{C_{V,m}+RP_{ext}P_f} T_i](https://tex.z-dn.net/?f=T_f%20%3D%20%5Cfrac%7BC_%7BV%2Cm%7D%2BRP_%7Bext%7DP_i%7D%7BC_%7BV%2Cm%7D%2BRP_%7Bext%7DP_f%7D%20T_i)
putting values wet
=![\frac{2.5\times 8.314+8.314\left(10^5\right)\left(3.20\times 10^5\right)}{2.5\times 8.314+\left(8.314\right)\left(10^5\right)\left(10^5\right)}\times \:293](https://tex.z-dn.net/?f=%5Cfrac%7B2.5%5Ctimes%208.314%2B8.314%5Cleft%2810%5E5%5Cright%29%5Cleft%283.20%5Ctimes%2010%5E5%5Cright%29%7D%7B2.5%5Ctimes%208.314%2B%5Cleft%288.314%5Cright%29%5Cleft%2810%5E5%5Cright%29%5Cleft%2810%5E5%5Cright%29%7D%5Ctimes%20%5C%3A293)
T_f = 615.3 K
Explanation:
To give the glass its final shape and size, it is blown into with a blowpipe, creating a sort of bubble of glass. To carry out this process, the blowpipe holding the glass must be placed on a steel stand. Then, the glass artist has to blow into the blowpipe while rotating it at the same
