PH can be calculated using the following equation
pH = -log [H₃O⁺]
for apple juice the hydronium /hydrogen ion concentration is 0.0003
pH = -log (0.0003)
pH = 3.5
correct answer is C
For ammonia
pH = -log (3.1 x 10⁻⁹)
pH = 8.5
answer should be 8.5
Answer:
-82/3
Step-by-step explanation:
first divide -8/9 by -2/3
-8/9 ➗ -2/3 =-8/9*3/-2 =4/3
multiply 4/3 by -41/2
4/3*-41/2 = -82/3
Answer:
ummm- i dont really know this one- but i think the answer is 0
Step-by-step explanation:
I think it would be layer 4
When you subtract the length of the base from the length of the side, you get
(ax+9) - (4x+b) = (a-4)x +(9-b)
