No its a combustion reaction, not a double replacement
This equation is not balanced correctly. This is an example of a redox reaction.
2 C2H6 + 7 O2 → 4 CO2 + 6 H2O Every thing balanced first but O2. Leave that for last.
Balanced equation first. 2C2H6 + 7O2 -> 4CO2 +6H2O I suspect C2H6 of limiting the reaction. 2 moles C2H6 (1.6 moles O2/2 moles C2H6) = 1.6 moles O2 left over and all of the C2H6 is consumed.
2C2H6 + 7O2 -> 4CO2 + 6H2O
You mean balance it? 2C2H6 + 7O2 -> 4CO2 + 6H2O
This chemical reaction is: 2 C2H6 + 7 O2 â†’ 4 CO2 + 6 H2O
2C2H6 + 7O2 -> 4CO2 + 6H2O Always balance O2 last and pay attention to the hydrocarbon arrangement.
The reaction is:2 C2H6 + 7 O2 = 4 CO2 + 6 H2O
The chemical reaction is:2 C2H6 + 5 O2 = 4 CO + 6 H2O
C2H6 + 7/2 02 ------> 3H2O + 2Co2
2C2H6 + 7O2 -> 4CO2 + 6H2O Watch the carbohydrate and balance oxygen last.
To be balanced it would be: 2 C2H6 + 7 O2 = 4 CO2 + 6 H2O
Combustion reaction. (burning)
The anwer is 2 (C2H6) + 7(O2) =4 (CO2) + 6 ( H2O) left side : C=4 , H= 12, O=14 right side : C=4 , H= 12, O=14 so they are balanced.
Its a Synthesis reaction.
S + O2 --> SO2 is a combination reaction
2H2O--->2H2 + O2 is a redox reaction because electrons are exchanged during electrolysis.
2c2h6+7o2 = 4co2 + 6h20 c2h6+7/2o2=2co2+3h20
2C2H6+7O2----->4CO2+6H2O 74g of C2H6= 2.4667 mol of C2H6 from the ratio(2/7), 8.633 mol of O2 are needed which is 276.256g (8.633mol×32g(molar mass))
This is the reaction for the oxydation (burning) of methane. CH4 + 2 O2 = CO2 + 2 H2O
