You are given the reaction cu + hno3 → cu(no3)2 + no + h20 half-reactions 3cu — 3cu2+ +6e 2n5+ + 6e → 2n2+ complete the final balanced equation based on the half-reactions

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .

= 5

step-by-step explanation:

to find the 15th term substitute n = 15 into the nth term formula

= (- 3 × 15 ) + 50 = - 45 + 50 = 5

1st part is 64,000,000

2nd part 500,000
