What is the maximum mass in grams of NH3 that can be produced by the reaction of 1.0g of N2 with 3.0g of H2?
what is the value of Kc for the following reaction at equilibrium: CO2(g) + H2(g) CO(g) + H2O(g) if [CO]=.20 M, [H2O]=.30 M, [CO2]=.30 M, and [H2]=.033M?
The density of a 16.0 mass % solution of sulfuric acid in water is 1.1094{g/mL} at 25.0 degrees celcius.
How many grams of dry NH4Cl need to be added to 2.50 L of a 0.700M solution of ammonia, NH3, to prepare a buffer solution that ahs a pH of 8.61?
Methylamine (CH3NH2) is a weak base. In a 0.100 M solution, 6.30% of the base is ionized. What is its Kb
Many drugs are high-molecular-weight amines that are weak bases. Such amines are not soluble in water, which limits the ways they can be administered and means that they are not soluble in body fluids such as blood plasma and cerebrospinal fluid
The temperature of the water rose t oa final temperature of 27.84 C. Neglecting heat loss to the room and the heat capacity of the beaker itself, what is the specific heat of the alloy?
A person ate 0.919 pound of cheese (an energy intake of 7350 kJ). Suppose that none of the energy was stored in his body. What mass (in grams) of water would he need to perspire in order to maintain his original temperature? (It takes 44.0 kJ to v..
Determine the percent yield for the reaction between 45.9g of NaBr and excess chlorine gas to produce 12.8g of NaCl and an unknown quantity of bromine gas.
Draw the structure of the geometric isomer of 2-pentene that has the lower melting point.
If 97.3 L of NO2 forms, measured at 35 C and 632 mm Hg, what is the percent yield?
A gas expands and does P-V work on the surroundings equal to 325J. At the same time, it absorbs 127J of heat from the surroundings. Calculate the change in energy of the gas. How do I solve this?
what volume of ethylene glycol, a nonelectrolyte, must be added to 15.0 Liters of water to produce an antifreeze solution with a freezing point of - 30 degrees celcius? what is the boiling point of the solution?
