If 5.00 x 10^3 kg each of NH3, O2, and CH4 are reacted, what mass of HCN and of H2O will be produced, assuming 100% yield?
Determine the number of representative particles in each substance.
A 25.0 mL sample of 0.150 M nitrous acid is titrated with a 0.150 M NaOH solution. What is the pH at the equivalence point? The Ka of nitrous acid is 4.50 x 10-4.
A typical aspirin tablet contains 325 mg of acetylsalicylic acid ( HC9H7O4). Calculate the pH of a solution that is prepared by dissolving five aspirin tablet(s) in one cup (237 mL) of solution. Assume the aspirin tablets are pure acetylsalicylic ..
If 3.00 g of (NH4)2SO4 is dissolved in enough water to form 200. mL of solution, what is the molarity of the solution?
how much energy (MJ) can be obtained from incineration and how much CO2 (kg/year) may be released in that year? 2) How much of that energy (MJ) can be actually converted into electric power if the conversion efficiency is 23%?

Desribing molecular forces of C5H6O, CH2=CH-CH=CH-CH=O, THREE double bonds. We are asked to describe the bond and angle terms of this structure.
A 0.30 M solution of sucrose (C12H22O11) at 37oC has approximately the same osmotic pressure as blood. What is the osmotic pressure of blood?
What are the respective concentrations (M) of Na and SO4 ions formed by dissolving 0.600 mol Na2SO4 in 135 mL water?
if 646 mL of gas at 280 K Is heated to 297 K, what will the new volume be? using charles's law
A fixed quantity of gas at 24 C exhibits a pressure of 745 torr and occupies a volume of 4.40 L. Use Boyle's law to calculate the volume the gas will occupy if the pressure is increased to 1.88 atm while the temperature is held constant.
.At 25°C and 1.0 atm, 0.25 g of a gas dissolves in 1.00 L of water. What mass of the gas dissolves in 1.00 L of water at 25°C and 3.0 atm?
