love the pfp
x^2*(-3x)=-3x^3. The power of x becomes 3 because you add the powers of x. (2+1=3)
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
