Define vector addition as y_1⊕ y_2=y_1+y_2-3 and scalar multiplication as c ⊙y_1=cy_1-3c+3. Let V be the space of all solutions of the equation in problem 3 that uses the above definitions of vector addition and scalar multiplication. Use the Vector Space Definition to prove that V is a vector space

6.5 We have postulated an RGB model for the material properties
of surfaces. Give
an argument for using a subtractive color model instead.
6.7 Show that if v lies in the same plane as l, n, and r, then
the halfway angle
satisfies
2ψ = φ.
What relationship is there between the angles if v is not coplanar
with the other
vectors?

If a platinum indicator electrode is used to measure [Cu2+] (standard reduction potential of Cu2+ is 0.337 V), and [Cu2+] = 0.0053 M, what is the cell potential (V) if the reference electrode is SCE and the measurement is taken at 298 K?
I have gotten .270 and .073, Im not sure what I am doing wrong
