Question

Balance the chemical equation for the important industrial process: C2H4 + O2 + HCl → C2H4Cl2 + H2O. Given 760.0 kg of molecular oxygen, calculate how many kg of C2H4Cl2 can be produced.

These are a mix (maybe) of ionic and covalent compounds: Name these compounds. Spell sulfide with the f not the ph. If the metal is a transition metal, you will need to use roman numerals in parentheses, no space between the metal and the parentheses, e.g. iron(III) oxide Covalent compounds should follow IUPAC naming methods.


What is the name for CS₂?  
What is the name for N₂O?  
What is the name for Fe₂O₃?  
What is the name for PBr₃?

Answer 1

1) to find killogram of C₂H₄Cl₂ produced

given mass of O₂ available for reaction = 760 killogram , mass in gram = mass in killogram x 1000

substitute values to find mass of O₂ availble in gram

mass of O₂ available for reaction in gram = 760 x 1000 = 760000 gram

molar mass of O₂ = 31.9988 gram/mole

no of moles = mass in gram/molar mass , substitute values to find no of moles of O₂ available for reaction

no of moles of O₂ available for reaction = 760000/31.9988 = 23750.89 moles

balanced chemical reaction is given bellow

2C₂H₄ + O₂ + 4HCl   2C₂H₄Cl₂ + 2H₂O   

according to reaction 1 mole of O₂ produces 2 moles of C₂H₄Cl₂  

therefore 23750 moles of O₂ will produce = 23750.89 x 2 = 47501.78 moles of C₂H₄Cl₂   

no of moles of C₂H₄Cl₂ can be produced = 47501.78 moles , molar mass of C₂H₄Cl₂ = 98.96 gram/moles

mass in gram = no of moles x molar mass , substitute values to find grams of C₂H₄Cl₂ produced

grams of C₂H₄Cl₂ produced = 47501.78 x 98.96 = 4700776.148 gram

mass in killogram = mass in gram/1000 substitute values to find killograms of C₂H₄Cl₂ produced

mass of C₂H₄Cl₂ produced in killogram = 4700776.148/1000 = 4700.776148 killogram

ans 4700.776148 Kg of C₂H₄Cl₂ can be produced from 760 Kg of molecular oxigen

2) to write names of given chemicals

ans name of CS₂ is carbon disulfide

name of N₂O is dinitrogen monoxide

name of Fe₂O₃ is Iron(III)oxide   

name of PBr₃ is phosphorus tribromide     

3) to find increasing order of electronegativity

increasing order of electronegativity is given bellow

Al,In,Ga,B,O
