Consider the combustion reaction between 30.0mL of liquid methanol ( density = 0.850 g/mL) and 15.0L of oxygen gas measured at STP. The products of the reaction are CO2 and H2O. Please use these numbers and EXPLAIN. Calculate the VOLUME (mL) of liquid H2O formed if the reaction goes to completion and you condense the water vapor.
A solution is made by dissolving 0.040 moles of the weak acid HA in water to make 1.00 L of a solution whose pH is 4.90. Calculate the Ka for the acid.
Using different methods, like equations of state SRK and PR what would be the nessceary steps to be able to determine a value from a given Pressure and Temperature using with:
What is the pH of the resulting solution if 15.0 ml of 0.450M NaH2PO4 is mixed with 20.0 ml of 0.350M Na2HPO4?
How much will the pH change? The pKa of acetic acid is 4.760.
Calculate the pH of a solution containing 0.085 M nitrous acid (HNO2; Ka= 4.4 × 10-4) and 0.10 M potassium nitrite (KNO2).
heat capacity of the calorimeter which is 10.17kJ/Degree Celsius and the temperature rose 105 Degrees Celsius. How many FOOD CALORIES does this cookie contain?
explain what would happen to the cell during the process of osmosis and why?
When the one ore lead (ii) sulfide burns in ixygen, the products are lead (ii) oxide and sulfur dioxide A. How many grams of oxygen are required to react with 0.126 mole lead (ii) sulfide?
A sample that weighs 0.1586 grams contains only sodium chloride and potassium chloride was dissolved in water. It took 22.90 mL of 0.1000 AgNO3 to precipitate all of the chloride present.
Some observations through an experiment shows that a gas sample of 115 mili litres has a mass of 0.170 grams at a pressure of 711mmHg and a temperature of 34 degree celsius. Determine the molar mass of the gas.
Kp for the reaction of SO2(g) with O2 to produce SO3(g) is 3 × 1024 . Calculate Kc for this equilibrium at 25ºC. (The relevant reaction is 2SO2(g) + O2(g) 2SO3(g).)
Write the balanced formula unit equation for the reaction of magnesium with hydrochloric acid. What is the sum of the coefficients? Don't forget coefficients of one
