As2O3(s) + NO3-(aq) --> H3AsO4(aq) + N2O3(aq) (acidic solution) what is the oxidizing and reducing agent?
A 24 L sample of a gas at fixed mass and constant temperature exerts a pressure of 3.0 atm. What pressure will the gas exert if the volume is changed to 16 L?
When C2H5OH +3O2 produces 2CO2 + 3H2O,determine how many grams of oxygen gas are essential for complete combustion of 421grams of ethanol ?
A solution is prepared by mixing 63.0 mL of 5.00 M HCl and 20.0 mL of 8.00 M HNO3. Water is then added until the final volume is 1.00 L. Calculate [H+], [OH -], and the pH for this solution.
Determine what would the pressure be if the volume of this sample gas is decreased to 5.38 Litre also state that which law of gas is used in this process?
How many molecules of carbon dioxide are produced when 130 molecules of acetylene (HCCH) to react in excess oxygen produce carbon dioxide and water.
"Crossed" or "mixed" aldol condensations are practical for synthesis, if one of the aldehydes (or ketones) has no alpha-hydrogen atoms. Explain.
An acid solution is 0.100 M in HCl and 0.190 M in H2SO4.What volume of a 0.150 M KOH solution would have to be added to 550.0 mL of the acidic solution to neutralize completely all of the acid?
An organic liquid is a mixture of methyl alcohol and ethyl alcohol. A 0.220g sample of the liquid is burned in an excess of O2(g) and yields 0.342 g CO2(g). What is the mass of methyl alcohol in the sample?
