Determine the entropy change when 1.80 mol of HBr (g) condenses at atmospheric pressure?

Imagine you were doing a calorimetry experiment to measure the molar enthalpy change for dissolving ammonium chloride (NH4Cl (s)) in water, H2O (l) to create an aqueous NH4Cl (aq) solution.

For the reaction, calculate how many moles of the product form when 0.012 mol of O2 completely reacts. Assume that there is more than enough of the other reactant. 4Al (s) + 3O2 (g) →2Al2O3 (s) Express your answer using two significant figures.

Nuclei with too many or too few neutrons are?

Be sure to answer all parts. Enter the formula for potassium dihydrogen phosphate and determine its molecular (formula) mass.

g Gaseous ethane will react with gaseous oxygen to produce gaseous carbon dioxide and gaseous water. Suppose 2.71 g of ethane is mixed with 3.8 g of oxygen. Calculate the maximum mass of carbon dioxide that could be produced by the chemical reaction.
