If you have a beaker of gas and all of the gas in that beaker is moved to a container half the size, the temp is maintained, what would the gas look like
NH4ClO4 ignites and burns in the absence of any other material to produce N2, HCl, H2O and O2. Write the balanced chemical equation for this process and determine the mass of H2O produced.
A solution contains a mixture of pentane and hexane at room temperature. The solution has a vapor pressure of 268 {rm torr}. Pure pentane and hexane have vapor pressures of 425 {rm torr} and 151 {rm torr}, respectively, at room temperature. What i..
