Answer) -3/4 or decimal form -0.75
Andrew is wrong The mat is only 100 times bigger than the unit, hope this helps :D
(4i)^3 = (4)^3 x (i)^3 = 64 x -i = -64i
Combine like-terms
-2.1x and 4.9x = 2.8x
3.7 and 5 = 8.7
2.8x + 8.7 is your final answer.
The reaction is:
A ( g ) + 1/2 B ( g ) → C ( g )
We will rewrite it so the coefficient in the front of C is 1:
1/2 A + 1/4 B → C
So the rate of increasing of C is 4 times faster than the decrease of B.
The rate of B:
- 1.5 · 10^(-2) M/s : 4 = - 0.375 · 10^(-2) M/s = - 3.75 · 10 ^(-3) M/s
Answer: - 3.75 ·10^(-3) M/s
