Prove the equilibrium law of pressure kp=kc(RT)^delta n

The solution is in the pictures because the picture is large, so I cut it and also put numbers on it to know it in sequence .

I hope I helped you^_^

answer: mercury

explanation:

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z
