An excess of AgNO3 reacts with 110.5mL of an AlCl3 solution to give 0.215g of AgCl. The concentration of the AlCl3 solution is Blank 1M. AlCl3 + 3AgNO3 ---> 3AgCl + Al(NO3)3 Write answer to three significant figures in decimal form(NOT in scientific notation)
Energy cost of dissociation was found to be 4 kWh/m3 of CO2. Calculate conversion degree of CO2 into CO and O2 in this system.
From the Mn concentrations (3.56ppm and 3.71ppm) and uncertainty
The Br-F bond distance in the interhalogen compound BrF is 1.76 Å. Use this information to estimate the average
By mistake, a worker at an electroplating shop mixes a small amount of sulfuric acid into a large tank of wastewater containing sodium cyanide. The reaction produces a toxic gas, hydrogen cyanide, as shown below:
Which molecular species would be necessary for the formation of the product in the reaction; a primary carbocation, a tertiary carbocation, a primary carbanion, a secondary carbanion or SO4?
A cube of lead (? = 11.3 x 103 kg/m3) is placed in a pool mercury (? = 13.6 x 103 kg/m3). The cube of lead is 3.60 x 102 cm on a side. Calculate the percentage of the cube that is above the pool of mercury.
Calculate the pH after the following amounts of NaOH are added. A) 0mL NaOH added( before the titration started)
A container (8.65-L ) holds two gases mixture at 31 °C. The partial pressures of gas X and gas Y, respectively, are 0.206 atm and 0.867 atm. If 0.200 mol a third gas is added with no change in temperature or volume determine the total pressure be..
The first-order decomposition of N2O5 proceeds as follows: 2 N2O5 (g) → 4 NO2 (g) + O2
Use the initial volume of acetic acid, the volume of NaOH required to reach the equivalence point and the value of the molarity of NaOH that you obtained when you standardized this solution against KHP in the strong-acid/strong-base experiment to ..
The heats of endothermic reactions are assumed the same as the heats of exothermic reactions, thus neglected for this estimation. The heat capacity of this woody biomass, 2.72 kJ/kg·?C, is assumed constant.
