1. Write a balanced equation for the reaction of calcium phosphide with water to produce phosphine and calcium hydroxide, in a atmosphere of carbon dioxide at 0C and a pressure of 4.8mm Hg. At STP carbon dioxide has a density of 1.96g/litre, and phosphine has a density of 1.53g/litre. Liquid water is used in the reaction. Pl ...continues
emphirical formula of a hydride,volume, density,molecular formula.
1. The phosphine that is produced by the reaction of water on calcium phosphide contains an impurity, another gaseous hydride of phosphorus, this hydryde contains 94% phosphorus and 6% hydrogen by mass. Calculate the emphirical formula using the percentages. 2. At 136.5C and a pressure of 760 mmHg, 0.22g of the hydride occupi ...continues
The question arises concerning the density of saltwater: is it because water molecules have moved out of the system, replaced by sodium and chlorine ions, which are heavier, or have the ions moved into the interstices, creating a greater number of particles in the solution? By the gas laws, a cubic meter of gas always maintain ...continues
How do we measure the oxygen that is released from the reduction of Hydrogen peroxide?
If I had a lab where I had Hydrogen peroxide which is reduced in the presence of a catalyst to oxygen and water, how can I measure the amount of oxygen that would be released?
Please take a look at the attached lab report on vapor density. Please see the ** items regarding percentage error and calculation of R. I can't figure out how to do the percentage error of my trials and the calculations for the R values are confusing. Thanks for your help. --- Vapor Density and the Ideal Gas Law Lab Con ...continues
