The heat of combustion of ethanol, C2H5OH(l) , is -1367 kj/mol. A batch of Sauvignon Blanc wine contains 10.6% ethanol by mass. Assuming the density of the wine to be 1.0 g/ml, what caloric content does the alcohol (ethanol) in a 6-oz glass of wine (177ml ) have?
A sample of material contains contains 20 mg of Iodine ^131. Calculate: A) The number of I ^131 atoms initially present. B) The activity in becquerels and curies.
when zinc metal is placed into a copper (II) nitrate solution, a single-displacement reaction occurs. Write a balanced equation to describe this reaction.
What volume of 6.00 M sodium hydroxide in milliliters must be diluted to 232.0 mL to make a 1.50 M solution of sodium hydroxide
The delta G for the reaction is 2.60 kj/mol at 25 degrees C. The initial pressures are P H2 = 3.34 atm, P I2 = 0.024 atm and P HI = 0.24 atm.
Oxygen is more electronegative than nitrogen; fluorine is more electronegative than the other halogens. Fluoride is a stronger field ligand than the other halogens, but ammonia is a stronger field ligand than water. Why
