3.)0.0836 g of solid potassium bicarbonate is used to standardize a magnesium hydroxide solution to be used in titrations in a lab. Phenolphthalein is used as an indicator to identify the equivalent point.
A. Write the balanced equation.
B. Write the net ionic reaction
C. Calculate is the molarity of the magnesium hydroxide solution if it takes 23.9 mL of the solution to neutralize the potassium bicarbonate.
4. A high-altitude weather balloon is filled with 268 cu/ft of hydrogen (g) will have a diameter of about 8 ft at sea level, but as the balloon climbs through the atmosphere it will expand to 35ft in diameter and will have a volume of 22,449 cu/ft before it pops. At 100,00 feet in elevation the temperature is -51.10∘F. The Balloon is released at a temperature of 4.85∘C and a pressure of 14.496 psi. Calculate the pressure in atm at 100,000 ft when the balloon "pops".
