Glycine is reacted with nitrous acid in-situ(produced from reaction of acetic acid and sodium nitritr) to form aqueous 2-hydroxyethanoic acid, nigren gas and liquid water. Write the equation for this reaction. Then calculate the difference between the Gibbs free energy and Helmholtz free energy for this reaction at normal temperatures and pressures.
How many grams of carbon monoxide (CO) are produced from a mixture of 70.0g SiO2 and 50.0 g of carbon. The balance ewaution is given below.
The activation energy for the following reaction is 60. kJ/mol. Sn2+ + 2Co3+ → Sn4+ + 2Co2+
For a reaction at equilibrium, which of the following is the best way to think about it?
Calculate deltaS for this reaction at 200 ºC (again assume Cp is independent of temperature)
then we cooled in an ice bath. then we washed it with water. and then added bicarbonate to netralize any acetic acid or sulfuric acid present. then we did an an extraction.
A solution was prepared by mixing 70ml of 4.00 mol/L HCl and 30.0 mL of 8.00 mol/L HNO3. Water was then added until the final volume was 500ml. What is the [H+] and what is the pH ?
A 80.0-L stainless steel container was charged with 4.00 atm of hydrogen gas and 5.00 atm of oxygen gas. A spark ignited the mixture, producing water. What is the pressure in the tank at a constant temperature of 25°C?
a sample containing 1.50 moles of neon gas has a volume of 8.00 liters. what is the new volume if 25.0g of neon is added.
The resulting mixture exerts a pressure of 745 mm Hg at 95 C. What was the mass of the original sample?
Acetylene gas (C2H2) is produced as a result of the following reaction. CaC2(s)+2H2O(l) = C2H2(g)+Ca(OH)2(aq) . If 32.0 g of CaC2 are consumed in this reaction, how many moles of H2O are needed?
