Answer: -

HCl (aq) and KOH (aq)

Explanation: -

Neutralization reaction is a type of reaction in which an acid and base react together to give salt and water.

A neutralization reaction is a type of double displacement reaction as well.

So if KCl is the salt that is formed then K should come from one and Cl from another.

Hence KOH and HCl are the acid and base that would neutralize to give KCl.

Answer:

  1. 0.1852
  2. 0.0947
  3. 0.7201
  4. 3.0345 kg CO_{2} / Kg C_{4} H_{10}
  5. 15.3848 Kg air / kg C_{4} H_{10}

Explanation:

Molar masses of each product are :

Butane = 58 kg /kmol

Oxygen = 32 kg/kmol

Nitrogen = 28 kg/kmol

water = 18 kg/kmol

<u><em>1) Calculate the mass fraction of carbon dioxide </em></u>

= ( 4 * 44 ) / ( (5 * 18) + (4 *44 )+ (24.44 * 28) )

= 176 / 950.32

= 0.1852

<em><u>2) Calculate the mass fraction of water </u></em>

= ( 5 * 18 ) /  (( 5* 18 ) + ( 4*44) + ( 24.44 * 28 ))

= 90 / 950.32

= 0.0947

<em><u>3) Calculate the mass fraction of Nitrogen </u></em>

= (24.44 * 28 ) / ((4 * 44 ) + ( 24.44 * 28 ) + ( 5 * 18 ))

= 684.32 / 950.32

= 0.7201

<em><u>4) Calculate the mass of Carbon dioxide in the products</u></em>

Mco2 = ( 4 * 44 ) / 58  = 3.0345 kg CO_{2} / Kg C_{4} H_{10}

<u>5) Mass of Air required per unit of fuel mass burned </u>

Mair = ( 6.5 * 32 + 24.44 *28 ) / 58  = 15.3848 Kg air / kg C_{4} H_{10}
