Coal can undergo an incomplete combustion in the absence of a plentiful supply of air to produce deadly carbon monoxide gas. What volume of carbon monoxide is produced at SATP by the incomplete combustion of 150. kg of coal?

For the combustion of hydrazine rocket fuel, N2H4(l), predict the volume of nitrogen dioxide produced at 850°C and 180 kPa, when 50.0 L of oxygen gas (measured at STP) is consumed.

Ammonium nitrate is widely used as a fertilizer, but it can also be used as an explosive. The decomposition of the solid ammonium nitrate produced nitrogen gas, oxygen gas and water vapour. Predict the numbers of molecules of water vapor that are produced along with 6.02 x 1023 molecules of nitrogen.

The reaction of 2,4,6-trinitrotoluene (TNT) and oxygen is given by the equation: 4 C7H5(NO2)3(l) + 21O2(g) → 28 CO2(g) + 6 N2(g) + 10 H2O(g)

Assuming all gases are measured at SATP, what volume of carbon dioxide is formed when 10.0 L of oxygen gas is consumed?

Oxygen gas generated by the decomposition of mercury(II) oxide is collected by the displacement of water. Given that the atmospheric pressure is 100.34 kPa and the water temperature is 24.0°C, predict the pressure of the oxygen.

calculate the wavelength (in nm) of a spectral line produced in the hydrogen spectrum, when an electron falls from the 4th energy level to the 2nd energy level. Which region of the electromagnetic spectrum does this spectral line belong to?

Describe the preparation of the following solution (show all calculations): 5.0 L of 6.000 M H3PO4 from a concentrated solution that is 85.1%(m/m) and has a specific gravity of 1.69

Kc = 57.0 at 700 K for the reaction shown below, which is conducted in a high pressure reactor. H₂(g) + I₂(g) ⇌ 2 HI(g). If [H₂(g)] = [I₂(g)] = 0.200 M at equilibrium, the molar concentration [HI((g)] = ________ at equilibrium

I have a problem with solving this question..


20cm3 of methane was released with 18cm3 of oxygen and it exploded.Calculate the volume of the resulting gas after the reaction mixture was cooled to room temperature.

Lead (Pb) (average atomic mass 207.19 amu) has three naturally-occurring isotopes, Pb206, Pb207and

Pb208 with isotopic masses of 205.98 amu, 206.98 amu and 207.98 amu respectively. If the isotopes Pb207and Pb208 are present in equal amounts, calculate the percent abundance of each isotope of Pb, which are, Pb206, Pb207 and Pb208.
