In the qualitative analysis of antimony, please assist with net ionic equations for Sb3+ with thioacetamide, Sb2S3 with NaOH, Sb2S3 with conc. HCL, and SBCl6- with H2C2O4 and thioacetamide.
determine the amount of heat (in kJ) given off when 1.42 * 10^4 g of NO2 is produced according to the following equation : 2 No(g) + o2(g) --> 2NO2(g) H = -114.6kj
when steam condenses to h2olliquid water heat of 2.26kj is released per gram. the heat from 168 grams of steam is used
What is the OH- in a solution that has a pH of 4.92? Give your answer to 3 significant figures using E-notation (i.e., 1 number before and 2 after the decimal point)
The EQ established when 2 moles of muck (s) are added to a 1 L solution of 3 moles of slop dissolved in slime (l) producing 1 mole of ick (g) and 2 moles of dissolved goo if the reaction goes the completion.
Draw the molecular orbital diagram for CO. Based on your diagram, why does CO always bond through the carbon and not the oxygen atom?
What is the solubility in pure water of Ba(IO3)2 in moles per liter at 25 ?C? [Ksp (25 ?C) = 6.0 x 10-10]
A scientist has a sample of gas that was collected several days earlier. The sample has a volume of 392 cm3 at a pressure of 0.987 atm and a temperature of 21°C. On the day the gas was collected, the temperature was 13°C and the pressure was 0.992..
Excess dietary fat can be converted to cholesterol in the liver. When palmitate labeled with 14C at every odd-numbered carbon is added to a liver homogenate, where does the label appear in mevalonate
Butane is normally supplied in metal containers under pressure, as a mixture of liquid and gas, so high temperatures may cause the container to explode. At 25.0 ºC, the vapor pressure of butane is 2.3 atm. What is the pressure in the container at ..
Substance A has a greater molar mass then substance B. Both are nonelectrolytes. If 50 g of substance A are dissolved in 250 g of water in one beaker
how much heat is released when 75.0 g of steam at 100.0°C is cooled to ice at -15.0°C? The enthalpy of vaporization of water is 40.67 kJ/mol
