Ideal Gas Law: Temperature, Volume & Pressure Given: Temperature of H2O = 200C Pressure = 0.95 atm Initial Air Volume = 50mL Final Air Volume = 95mL Volume of O2 collected = 95mL - 50mL = 45mL Total Reaction time = 17mins Balanced equation for hydrogen peroxide decomposition: 2H2O2 ------ 2H2 + O2 Using the Ideal Gas Law (PV = nRT), calculate the grams of O2 produced in the reaction above(decomposition of hydrogen peroxide). (Hint: solve for n, and then convert moles of O2 to grams. Watch your units; you may need to convert some of your data into different units.)
Atmospheric Pollution
In the atmosphere, the existence of large quantities of undesirable substances that could cause several health issues to living organisms and humans is atmospheric pollution. Air pollution is otherwise known to be atmospheric pollution. The presence of undesirable materials would also destruct the natural environment such as a change in climate, degradation of habitat, or depletion of ozone. Air pollution is generated by the natural processes and activities of humans.
Smokestack Scrubbers
Once we believe in the environment and remember the pollution-producing facets of it, we will consider the smoke-stacks scrubber to be a number of the worst offenders. Although this is often legally correct, smoke-stack scrubbers often have a big function in terms of keeping ground-level air pollutants- safe to breathe and assisting within the management of emissions.
Given:
Temperature of H2O = 200C
Pressure = 0.95 atm
Initial Air Volume = 50mL
Final Air Volume = 95mL
Volume of O2 collected = 95mL - 50mL = 45mL
Total Reaction time = 17mins
Balanced equation for hydrogen peroxide decomposition:
2H2O2 ------ 2H2 + O2
Using the Ideal Gas Law (PV = nRT), calculate the grams of O2 produced in the reaction above(decomposition of hydrogen peroxide). (Hint: solve for n, and then convert moles of O2 to grams. Watch your units; you may need to convert some of your data into different units.)
