The label on an aerosol spray can contains a warning that the can should not be heated to over 130°F because of the danger of explosion due to the pressure increase as it is heated. Calculate the potential volume of the gas contained in a 495 mL aerosol can when it is heated from 25°C to 54°C (approximately 130°F), assuming a constant pressure.
Determine the mass of phosphorus (P) is required to make 39 grams of this product?
A circular storage tank in the san Ardo california oil field water treatment facility is 50 yards in diameter. Estimate how many barrels of fluid this tank could hold
5.00 ml of a water sample was titrated for hardness with 4.15mL of 0.0200M EDTA. Write an equation for the reaction and calculate the hardness of the water in ppm
What volume of pure oxygen gas (O2) measured at 546 K and 1.00 atm is formed by complete dissociation of 0.7 mol of Ag2O? 2 Ag2O(s) → 4 Ag(s) + O2(g)
Predicting the Polarizability of a Molecule. Consider the following set of data for polarizability. From what I have learned, the simplest model for predicting the polarizability of a molecule is to assume that polarizability scales with the type.
An experiment requires 42.0 g of ethylene glycol, a liquid whose density is 1.114 g/mL. Rather than weigh the sample on a balance, a chemist chooses to dispense the liquid using a graduated cylinder.
A 5.0 mL sample of vinegar was titrated with 7.2 mL of 0.55 M NaOH(aq). If the density of the vinegar solution is 1.00 g/mL, what is the mass percent of acetic acid present?
