The combustion of ethane (C 2 H 6 ) produces carbon dioxide and steam. 2C 2 H 6 (g)+7O 2 (g) 4CO 2 (g)+6H 2 O(g)

How many moles of CO 2 are produced when 5.95 mol of ethane is burned in an excess of oxygen?

CO₂ produced : 11.92 moles

Further explanation

Reaction

2C₂H₆ (g)+7O₂ (g) ⇒4CO₂ (g)+6H₂O(g)

mol ratio C₂H₆ : CO₂ = 2 : 4

moles of CO₂ :

Bromine has atomic number  35  which means there are  35 protons  and  44  neutrons to give a total of 79 nucleons. the fact that it's a positive ion means that it has lost an electron; so there'll be  34 electrons.
