if 7.o moles of sulfur atoms and 10 moles of oxygen molecules are combined to form the maximum amount of sulfur trioxide, how many moles of which reactant remain unused at the end? 3S + 3O2 = 2SO3
Calculate the pH after 0.020 mol NaOH is added to 1.00 L of a solution which is 0.100 M NH2OH and 0.100 M HONH3Cl.
When 25mL of a 120mL stock solution containing 2M AlCl3 is diluted to 80mL, how many moles of Al3+ are in the new solution.
Just transfer this solution completely to a flask of 1L volumetric and dilute to exactly 1 liter and then compute the Fe 2+ ion concentration.
Find out what will be the half-lives if [NOBr]o = 0.054 M - The rate constant for the second order reaction Is 0.80 M-1s-1 at 10 degree celsius temperature
The heat of fusion of thallium is 21 j/g, and its heat of vaporation is 795j/g. The melting anf boiling points are 304 degress celcius. The specific heat of liquid thallium is 0.13 j/g*c.
Solving this question helps the student to understand how to find molecular formula using moles and mass and What is the molecular formula of this compound?
Write the expression for the equilibrium constant, Kb, for methylamine also compute the molar concentration of OH- in the 50.0 mL sample of the CH 3 NH 2 solution.
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.
If the gas was not pure butane but 10 mole percent propane and 90 mole percent butane then determine how would the MW value be affected?
What is the molaity of a solution prepared by dissolving 75.8 of ethylene glycol, HOCH2CH2OH, in 1.45 L of water? assume the density of water is 1.00 g/mL.
a solid acid is dissolved in enough water to make 200 ml of a solution. 40 ml of the solution is titrated to a phenolphthalein end point with an NaOH solution.
A solution contains 410.3 g of H2SO4 per litre of solution . If the density is 1.243 g/ml, what will be its molarity and molality.
