This is answer:
x(x+3)-x
or
1x(1x+3)-1x
1x+3x+-1x
=3x
First you multiply and then u would add the like terms.
Is it 0.092?
I got this by using the information from pH 4 which is 15 and doubling it to make 30 and taking away 5 (we get 5 from halving the the rate for reaction at pH6) to get 25.
0.071 x 2= 0.142
0.100/2 =0.05
0.142+0.05 =0.092
R+16=8
r = -8
Hope this helps!
