a) A natural gas fuel contains 80 v/o methane, 10 v/o ethane, and 10 v/o propane. Determine the heat released by combustion of 1m3 of the gas. Assume that products of combustion are CO2 and liquid H2O. b) How would the answer to part (a) change if the water produced were vaporized?
Methane, CH_4, is a gas room temperature but dichloromethane, CH_2Cl_2 is a liquid. Why? Water will rise up into a capillary tube. Why, and how is this phenomenon important in nature? Calculate the amount of heat in kJ that is required to heat 20.0g of ice from -25 degree C to 90 degree C, and sketch a heating curve for the process. The specific heat of ice is 2.11 J/(g, degree C); water 4.18 J/(g, degree C) and the Delta...
Part 2: pH and pOH Calculations 1) You dissolve 0.1500 moles of formic acid (monoprotic, K = 1.8 x 10-) in 2.50 L of water. Calculate the pH of this solution. Use the quadratic formula for this calculation (just to prove you can do it!), i.e., don't use the approximation that x «[...) 2) You dissolve 15.0 grams of propanoic acid (monoprotic, MW = 74.08 g/mol, Ka = 1.3 X 10"") in 95.00 ml of water. Calculate the pol of...
Question 4 2 pts If 11 drops of a formic acid (HCOOH) solution are titrated with 10 drops of a 0.12 M NaOH solution, what is the percent ionization of the formic acid solution? (Ka for formic acid 1.78 x 104) 4.0% 1.3% 1.9% @ 2.5% Question 5 2 pts What is the pH of an acetic acid solution if 25 drops are titrated with 44 drops of a 0.45 M KOH solution? (K, for acetic acid 1.8 x 105)...
A fuel gas that contains
mole% methane and the balance ethane is burned completely with
pure oxygen at
°C, and the products are cooled to
°C.
suppose that the combustion takes place in a constant-volume
batch reactor. Take
mol as a basis of calculation of the fuel gas charged into the
reactor and assume any percent excess oxygen,
and calculate –Q(kJ) for the cases of liquid water as
well as water vapor as products.

1) In a batch culture, formic acid (HCOOH) is produced using bacteria. For each mole of glucose (C H206) utilized by the bacteria, 2.40 moles of cells (CH1.8000 1No.26), 1.70 moles of formic acid, 1.90 moles of gaseous CO2, and some H20 are formed. Oxygen (O2) and ammonia (NH3) were consumed. Glucose, ammonia and 18,350 kg of water were fed to the reactor and inoculated with the bacteria. Air is pumped into the reactor and during the entire process 6000...

Physical Property Tables Continuous Reactor Suppose the reactor is continuous. Take a basis of calculation of 1.000 mol/s of the fuel gas, assume some value for the percent excess oxygen fed to the reactor (the value you choose will not affect the results), and calculate -Q (kw), the rate...

2. Natural gas containing a mixture of methane, ethane, propane, and butane is burned in a furnace with excess air. One hundred kmol/h of a gas containing 94.4 mole% methane, 3.40% ethane, 0.60% propane, and 0.50% butane is to be burned with 17% excess air. a) Calculate the molar flow rate of the air. b) Now instead of using numerical values, we will work the problem by deriving an equation. Define the following variables: i.molar flow of the fuel gas:...
3. Formic acid, HCOOH, is a weak acid with a pK, of 3.74. Draw up a reaction table for the reaction of 0.300 M formic acid with water, and calculate the pH of this solution. 4. Consider the following gas-phase equilibrium reaction: N(g) O,(g)2NOg K, 4.10x 10 at 2000°C If 1.0 mol of NO is introduced into a 1.0 L container at 2000 C, what is the concentration of NO when equilibrium is reached? 5.
