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:
Jen ate 18 jujubes
Step-by-step explanation:
Start with Kim. She was given 10. There is no remainder.
Kyle kept 8 from the total he was given, so Kyle had 18.
Let the number of Jujubes given to Jen = x
(1/2) x = 18 Multiply both sides by 2
2(1/2)x = 18*2
x = 36
Jen ate 1/2 of 36 which was 18.
Though you are not asked, Sam must have begun this with 2*36 = 72 Jujubes.
