The sum of the first nth term of a geometric series is 145 and the sum of the reciprocal is 145/33. The first term is 1. What is n and the common ratio? Precalculus

What we're really doing here is that we're given an initial state with # ["BrCl"]_i = "0.050 M"#, and we're given #K_ (eq)#, which is defined for a final state we define as equilibrium, when the rate of the …

First, subtract #color (red) ($145)# from each side of the equation to isolate the #w# term while keeping the equation balanced:

Solve: 1. sin x = 0.5623 2. cos x = 0.8963 3. tan x = -2.89 1. Calculator gives --> sin x = 0.5623 --> x = 34.22 and x = 180 - 34.22 = 145.78 deg. Extended answers: x = 34.22 + k360 deg x = 145.78 + k360 …

From this, the number of unpaired electrons seems to be: Number of unpaired electrons = S |ms| = 2.145 1/2 = 4.29 ≈ 4 So it looks like treating μS+L ≈ μS for Fe2+ is OK to determine the number of …
