Detail the products of combustion and the correlation between these products and firefighter safety, both during an incident and during salvage and overhaul of the structure. List and explain the safety measures that should be in place to ensure that firefighters are not affected by these products?
Place the following in order of increasing strength as reducing agents (all under standard conditions). (Use the appropriate symbol to separate substances in the list.) Cr3+, H2, Zn, Li, F -, Fe2+
The solution has a vapor pressure of 262 . Pure pentane and hexane have vapor pressures of 425 and 151 , respectively, at room temperature.What is the mole fraction of hexane? (Assume ideal behavior.)
calculate the amount of heat needed to convert 96g of ice at -24 degrees celcius to water at 28 degrees celcius. the
The cyanide ion, CN-, binds to the iron that red blood cells use to carry oxygen around the body, therefore interfering with the blood's ability to deliver oxygen to the tissues. It is this toxicity that has made the use of sodium cyanide in gold ..
