All ball is thrown into the air with an upward velocity of 24 ft/s. Its height h in feet after t seconds is given by the functio
n h=-16t^2+24t+7. a. In how many seconds does the ball reach its maximum height? Round to the nearest hundredth if necessary. What is the ball's maximum height?
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
