consider the following reaction :2Al + Cr2O3 = Al2O3 +2cr. what is the mass of Al2O3 that will be produced upon complete reaction of 1.20* 10^21 atoms of Al

a gas container contains 35.0 l at 150 bar determine the volume in l this gas will occupy if it were allowed to expand at atmospheric temperature room temperature

Give the Electronic configuration of titanium

A gas sample is initially at 3.3 atm and 8.7 L. If the volume is adjusted to 7.7, what is the new pressure of the gas sample? (Assume the sample is maintained in a closed container with constant temperature).

A closed container in lab contains a sample of oxygen gas. When the temperature in lab is 16.9 degrees Celcius, the pressure in the container is 10.1 atm. What would the temperature in lab be (in Celcius) if the pressure in the container was 11.9 atm? Assume the mol and volume of the container are constant. Record your answer as a number with the correct significant figures.

At STP how many mL will 6.7 mol of any gas occupy? Answer as a whole number

what mass of calcium will produce 10g of calcium oxide

The molar absorption coefficient of a solute at 440 nm is 423 dm3 mol-1 cm-1 . When light of that wavelength passes through a 6.50 mm cell containing a solution of the solute, 48.3 percent of the light is absorbed. What is the molar concentration of the solute?
