An 0.758 mol sample of neon gas at a temperature of 18.0 oC is found to occupy a volume of 24.0 liters. The pressure of this gas sample is. answer in mm Hg please.
double bond energy= 837 h single bond cl = 431 C single bond C = 347 C single bond H = 414 C single bond Cl 339 It says answer is -154 kJ but im not getting that
Determine which flask has the smallest amount of water vapour and which one has greater vapor pressure of H 2 O?
Determine the energies of ten lowest energy levels for this system.
How do you calculate solubility percentage? For example if a out 5 grams of sugar in 50 ml of water, with the temperature of water being 20 degrees.
degree C is mixed with 35.2 g/mL of water (density = 1.0 g/mL) initially at 24.4 degree C in an insulated beaker. Assuming that no heat is lost, what is the final temperature of the mixture?
Alkanes are organic molecules that contain only carbon and hydrogen atoms connected through single bonds. In the IUPAC naming system, all alkanes end in the suffix ane and begin with a prefix determined by the number of carbon atoms in the molecul..
write the equations for two different acid base reactions of diethylamine with water. Indicate the direction of the equlibrium for both reactions. The pKa of diethyl ammonium ion is 10.94.
The solute increases the volume of the solution, and an increase in volume requires an increase in the temperature to reach the boiling point (derived from PV = nRT).
calculate the molar concentration of all the ions remaining in solution after the reaction has taken place ... Cr(III), hydroxide, potassium, nitrate
A 0.1946 g piece of magnesium metal is burned in a constant volume calorimeter that has a heat capacity of 1349 J/°C.
7.2 liters of an ideal gas are contained at 4.0 atm and 27 °C. Using the ideal gas law, calculate how many moles of this gas are present.
Calculate the pH in a solution prepared by dissolving 0.08 mol of solid NH4CL in 0.450 L of 0.35 M NH_3. Assume that there is no volume change.
