Consider the equations below. CH,(9) →C(s)+2H2 (9) AH, = 74.6 kJ
C(s) + 2Cl2(g) → CCI (9) AH2 = -95.7 kJ
2H2(g) + 2Cl2(g) → 4HCI(9) AH2 = -184.6 kJ
CH, (g) + 4C12(g) → CCI,(9) + 4HCl(g) AH, = -205.7 kJ
Complete the following based on the diagram.
Arrow A:
Arrow B:
Arrow C:
Arrow D:

explanation: it gains negative electrons, therefore becoming negatively charged. as charge cannot be created, nor destroyed, only transferred, this leaves the wool positive. now that they have opposite charges, the two items attract.

consider the reaction below.

 no rx

at 500 k, the reaction is at equilibrium with the following concentrations.

[pci5]= 0.0095 m

[pci3] = 0.020

[ci2] = 0.020 m

what is the equilibrium constant for the given reaction?

0.042

0.42

2.4

24

i think its 100.

hope this !
