A mixture contains Al2O3(s) [MW = 101.96 g/mol and Fe2O2(s) [MW=159.69 g/mol] and weighs 1.9834g. When heated under excess hydrogen gas, the iron oxide reacts to form water vapor and Fe(s) but aluminum oxide remains unreacted. If the residue following heating weighs 1.6446g determine the wight percent of iron oxide in the original mixture.
Determine the partial pressure and total pressure of the gases and Find the partial pressure of carbon dioxide in a gas mixture
If 36 L of Hydrogen at 44 C and 94 kPa react with sufficient oxygen to produce water, what mass of water can be produced?
a critical reaction in the production of energy to do work or drive chemical in biological systems is the hydrolysis of adenosine triphosphate, ATP to adenosine diphosphate ADP
In the electrolysis of water, 2h20 yields 2h2 plus o2, if the volume of oxygen produced was 8ml, what would be the volume of hydrogen produced?
For a 0.13 M solution of formic acid, HCOOH, the pH = 2.40. Calculate Ka for formic acid.
What is the PH of .0750L of hypochlorous acid/hypochlorite buffer solution, originally .300M in HCLO and .400M in CLO-. after 7.5E-3 moles of NAOH have been added to the buffer
Stalactites--the long icicle, icicle like formations that hang from the ceilings of caves--are formed from recrystallizing minerals like calcite (calcium carbonate, CaCO3, 100.09 g/mol). The Ksp of calcium carbonate is 4.5 x 10^-9.
Car manufacturers are developing engines that use H2 as fuel. In locations where hydroelectric plants produce inexpensive electric power, the H2 can be made industrially by the electrolysis of water.
If 13.93 mL of NaOH solution is required to reach the stoichiometric point, what is the molar concentration of the sodium hydroxide solution?
4 C3H5O9N3(l) → 12 CO2(g) + 6 N2(g) + O2(g) + 10 H2O(g) If a sample containing 2.01 mL of nitroglycerine (density = 1.592 g/mL) is detonated, how many total moles of gas are produced?
A 100.0 g sample of a metal M is burned in air to produce 103.7 g of its oxide with the formula M2O. What is the atomic mass of the metal?
a 130g piece of metal is heated to 286C and dropped into 87.0g of water at 26C, if the final temperature of the water is 58.3C.
