A 2.60 mole quantity of NOCl was initially in a 1.50 L reaction chamber at 400°C. After equilibrium was established, it was found that 22.0 percent of the NOCl had dissociated: 2NOCl(g) 2NO(g) + Cl2(g) Calculate the equilibrium constant Kc for the reaction.
If 0.345 moles are produced during a reaction and collected at a temperature of 294K and pressire of .981 atm what volume will the gas occupy?
What is the value of x in the formula for the hydrate? (hint: remember that x represents the ratio of moles of H2O to moles of hydrate compound, and that moles of hydrate compound equals the moles of anhydrous compound)
A lab protocol on synthesizing sulfathiazole from p-acetamidobenzenesulfonyl chloride and 2-aminothiazole. It would be appreciated if exact amounts of reagents, solvents, etc (in grams, mmols, mls - etc), could be given.
Determine how many grams of NaCl should be dissolved in a liter of H 2 O to produce an isotonic solution?
Suppose that 28 g of gold is initially at 29.0 degrees celsius. What is the final temperature gold upon absorbing 2.25 kJ of heat?
The dipole moment and the normal boiling point of acetaldehyde (CH3CHO) are 2.7 D and 293 K, respectively. The dipole moment and the normal boiling point of n-octane (C8H18) are 0 D and 298 K.
an electron is confined to a linear region with a length of the same orderas the diameter of an atom (about 100 pm)
How many grams of IO2F are needed to react completely with 150.0 g of BrF3? 3IO2F(s) + 4BrF3(l) → 3IF5(l) + 2Br2(l) + 3O2(g)
Can an ether molecule be made out of a methanol or ethanol molecule? Why or why not? What is the structure for 1-Octanol & Propane-1,2,3-triol?
In a calorimeter, 10.0 g of ice melts at 0oC. The enthalpy of fusion of the ice is 334 J/g. How much heat was absorbed?
