Identify and discuss three key features associated with the combustion of polymeric materials or compounds that are relevant to the safety and health of an EH&S or a FS professional responding to an incident involving these materials.
Phosphoric acid, H3PO4(aq), is a triprotic acid, meaning that one molecule of the acid has three acidic protons. Estimate the pH, and the concentrations of all species
What is the magnitude of the change in pH when 0.005 moles of HCl is added to 0.100 L of a buffer solution that is 0.100 M in CH3CO2H and 0.100 M NaCH3CO2?
What is the molar concentration of a H3PO3 solution if 150.00 mL of the solution was required to neutralize 75.00 mL of NaOH whose concentration was 1.50 molar?
A gas cylinder containing 6.38 mol of neon has pressure of 491mmHg at 295k. If 3.22 mol helium is added at constant temp and pressure, what will be the pressure in the cylinder
how many heat energy is required to heat a cup of water (195.0) from room temperature (25.0C) to boiling (100.0C).
How many grams of oxygen gas are required to produce 7.68 kJ of heat when hydrogen gas burns at constant pressure to produce gaseous water?
A mixture consists of 323 mg of methane, 165 mg of argon, and 223 mg of nitrogen. The partial pressure of nitrogen at 275 k is 19 kPa.
