Question
what is an alkane? write general formula for alkane Name is single compound which represent a gasoline mixture. In the combustion of methane (CH_4): CH_4 +2O_2 rightarrow CO_2+2H_2O how many moles of oxygen are required if 10 mol of CH_4 is completely consumed how many moles of H_2O are formed in the reaction in the reaction: 2 H_2 (g) +O_2 (gas) rightarrow 2 H_2O (g) 10 mol H_2 and 10 mol of O_2 are used which recatant is a limiting reactant. In the reaction: 2H_ 2O_2 rightarrow 2 H_2O+O_2: how many moles of O_2 can be obtained by decomposition of 7.5 mol of reactant? Write at least 4 molar rations that can be obtained from the following equation: 2HCH +K_2CO_3 rightarrow 2KCL +CO_2 +H_2O what is the temperature and pressure at STP (standard Temperature and pressure ) standard specify the reasons for fuel additives In gasoline name six criteria pollutants in urban air as identified by environmental protection Agency. Name the variable for ideal gas Laws. If a photonExplanation / Answer
1) alkanes are simplest organic compounds formed by only c,H
general formula = Cn H2n+2
2)
a) 20 mol O2
b) 20 mol H2O
3) a) limitingreactant is H2
b) No of mol of O2 obtained = 7.5/2 = 3.75 mol
4)
a) 2 mol HCl = 1 mol K2CO3 = 2 mol KCl = 1 mol CO2 = 1 mol H2O
b) STP
T = 273.15 K , P = 1 atm
