What is the initail pH of this solution of hypobromous acid. What is the pH of the solution at the equivalence point
calculate the vapor pressure of the pressure cooker if the temperature inside the pressure cooker is 119 degree celcuis.
Problem- What is the density in (g/L) of a sample of nitrogen gas that occupies a volume of 6.78L at a pressure of 2.43 atm and temperature of 40.6 degrees Celsius
On a smoggy day in a certain city the ozone concentration was 0.54 ppm by volume. Calculate the partial pressure of ozone and the number of ozone molecules per liter of air if the temperature and pressure
Methane and oxygen react to form carbon dioxide and water. Explain what mass of water is formed if 3.2g of methane reacts with 12.8 g of oxygen to produce 8.8 g of carbon dioxide
Two molecules of 1,3-butadiene (C4H6) react to form 1,5-cyclooctadiene (C8H12). As the Reaction proceeds, the pressure in the container falls, because two gas molecules are consumed to produce one product molecule.
