<span>2C2H6 + 7O2 = 4CO2 + 6H2O
</span>
According to the equation of the reaction of ethane combustion, ethane and carbon dioxide have following stoichiometric ratio:
n(C2H6) : n(CO2) = 1 : 2
n(CO2) = 2 x n(C2H6)
n(CO2) = 2 x 5.2 = 10.4 mole of CO2 is formed

Answer: 
, product favoured
Explanation:
Complete ionic equation : In complete ionic equation, all the substance that are strong electrolyte and present in an aqueous are represented in the form of ions.
Net ionic equation : In the net ionic equations, we do not include the spectator ions in the equations.
When hydrochloric acid react with potassium cyanide, then it gives potassium chloride and hydrocyanic acid as products.
The complete ionic equation will be:
The net ionic equation will not contain spectator ions which are 
and 
:
The reaction is product favoured.
Answer:
The new pressure at constant volume is 1066.56 kPa
Explanation:
Assuming constant volume, the pressure is diectly proportional to the temperature of a gas.
Mathematically, P1/T1 = P2 /T2
P1 = 880 kPA= 880 *10^3 Pa
T1 = 250 K
T2 = 303 K
P2 =?
Substituting for P2
P2 = P1 T2/ T1
P2 = 880 kPa * 303 / 250
P2 = 266,640 kPa/ 250
P2 = 1066.56 kPa.
The new pressure of the gas is 1066.56 kPa
Answer:
Remove the outer layer of sodium oxide that formed to allow for a quicker reaction
Explanation:
The purpose of not using a paper towel to dab off your metal is :
Remove the outer layer of sodium oxide that formed to allow for a quicker reaction.
The process of Dabbing is nothing but applying doses of a cannabis concentrate that gets vaporized on a surface which is heated up.
The daboff the metal by normal paper towel cannot remove the outer oxide layer.
