Methane (ch4), ammonia (nh3), and oxygen (o2) can react to form hydrogen cyanide (hcn) and water according to this equation: ch4 + nh3 + o2  hcn + h2o you have 10 g of methane and 12 g of ammonia in excess oxygen. answer the following questions: what is the balanced equation for this reaction? which reagent is limiting? explain why. how many grams of hydrogen cyanide will be formed? show your work.

2CH4 + 2NH3 + 3O2 ---> 2HCN + 6H2O

10g CH4 x 1molCH4/16.042gCH4 x 2mol HCN/2molCH4 = 0.6mol HCN

12g NH3 x 1molNH3/17.034gNH3 x 2molHCN/2molNH3 = 0.7mol HCN

Methane is the limiting reactant

Use the moles of Hydrogen Cyanide that you would get when used the limiting reactant, Methane

0.6molHCN x 27.028gHCN/1molHCN = 16.2grams --> 16 grams Methane

Decomposition is the cycle at which bacteria breaks down any organic material into the soil

You would be correct, boiling water does disinfect contamination.    the property of disinfecting means to kill  germs, bacteria and other pathogens or contamination  that might cause an infection or cause a person to become sickly. a couple methods of disinfecting are using soap, other cleaning supplies or by simply "boiling" the contaminate.  the reason why boiling water disinfects certain attributes is because some cells cannot survive the heat and pressure.
