How many grams of sulfur (S) are needed to react completely with 355g of mercury (Hg) to form HgS?
A voltaic cell is based on the reaction Sn + I2 = Sn2+ + 2I-.
Determine how long will it take for the concentration to decrease to 0.13 mol/L express your answer in seconds.
When one mole of benzene (C6H6) undergoes complete combustion, 3,170 kJ are released. Calculate the combustion energy of 0.350 kg of benzene?
Determine the limiting reactant and the numbers of moles of Cu will be formed If you place .092 mol of iron filling in a solution containing .158 mol of Copper sulphate,?
A gas sample containing 1.64 mol at 25°C exerts a pressure of 389 torr. Some gas is added to the same container, and the temperature is increased to 50.°C.
How many liters of O2 are needed to react completely with 45.0L of H2S at STP? 2H2S(g) + 3O2(g) -> 2SO2(g) +2H20(g)
Draw all stereoisomers having molecular formula C6H12 that contain one double bond and give the IUPAC name for each compound
what the oxidation state P in PO4^-2? what the oxidation state O in PO4^-2?
However, if you treat formaldehyde (CH2O) with potassium cyanide in water, you will not produce the cyanohydrin. You may even produce C3H6O3 (i.e., dihydroxyacetone and glyceraldehyde). Explain this either in words or reactions.
Calculate concentrations of OH- and the pH of each basic solution. Since NaOH donates on OH- ion for each NaOH molecule, the OH- concentration is equivalent to the NaOH molarity. The pOH is calculated as -log[OH-] and the pH is calculated as 14-pO..
Determine the percent yield for this reaction as N2(g) + 3 H2(g) ? 2 NH3(g)
If 329 g water at 65.7°C loses 9730 J of heat, what is the final temperature of the water?
