Given:
pH = 4.2 of tomato
Required:
hydrogen-ion concentration [H+]| for tomato juice
Solution:
The formula for the pH relating hydrogen ion concentration is pH =
-log[H+] where H+ is the hydrogen ion concentration. so, substitute the value
of pH
pH = -log[H+]
4 = - log[H+]
-4 = log[H+]
10^-4 = [H+]
[H+] = 1x10^-4M
Answer:
-36s + 54
Step-by-step explanation:
−9(5s − 6) + 9s =
-45s + 54 + 9s =
-36s + 54
-11 1/3 = -34/3
Because 3(-11) = -33 -1 = -34/3
Answer:
x= -5
Step-by-step explanation:
let the number be x.
2x+5= -5 ====> equation
2x= -5-5. (shifted the +5 to the other side)
2x= -10
x= -10/2 ( shifted 2 on the other side as it was multiplying with x)
x= -5
What you have to do here, is replace n with 3 and multiply 0.53(3) and you will get your first answer. Do the same thing with -3: multiply 0.53(-3) and you will have your second answer. If you do this, I do believe your question will be answered.
