Hydrogen ions cannot exist alone but they exist after combining with water molecules true or false​
juin [17]
True because hydrogen ions combines with h2o to make hydronium ion, so in a sense h2o is acting like a base.

0.60 atm of SO3 and 0.30 atm of SO2are placed in a container and the system is allowed to reach equilibrium. Calculate the press
frozen [14]

Complete Question

The complete question is shown on the first uploaded image

Answer:

The pressure is [O_2] =  4.8 *10^{-5} \ atm

Explanation:

From the question we are told that

     The  pressure of  SO_3 is  [SO_3 ] =  0.63 \ atm

     The  pressure of  SO_2 is  [SO_ 2]  =  0.30 \ atm

      The equilibrium constant is K_p  =  1.2 *10^{-5}

     The  reaction is

           2SO_3 _{(g)} ⇔ 2SO_2_{(g)} +  O_2 _{(g)}

Generally the equilibrium constant is mathematically represented as

           K_p  =  \frac{(SO_2)^2 *  (O_2)}{(SO_3)^2}

=>         [O_2] =  \frac{k_p * [SO_3] ^2 }{[SO_2]^2}

substituting values

            [O_2] =  \frac{1.2 *10^{-5} * 0.60 ^2 }{0.30^2}

             [O_2] =  4.8 *10^{-5} \ atm

In a combustion chamber, ethane (c2h6) is burned at a rate of 9 kg/h with air that enters the combustion chamber at a rate of 17
nekit [7.7K]

The percentage of excess air used during combustion process of ethane will be 37 %.

Burning, also known as combustion, would be a high-temperature highly exothermic chemical process that occurs when an oxidant, typically atmospheric oxygen, interacts with a fuel to generate oxidized, frequently gaseous products in a mixture known as smoke.

Calculation of percentage of air .

C_{2} H_{6} + (1-x)+a(O_{2} +3.76N_{2} )=bCO_{2}  + cH_{2} O + axO_{2}  + 3.76dN_{2} .

Mair=Mair/Rin

( MN)O_{2} + (MN)N_{2}÷ (MN)O_{2} + (MN)N_{2} +(MN)C_{2} H_{6} .

33 . 3.25(1-x) + 28 × 13.16(1-x) ÷ 33 × 3.25(1-x) + 28 × 13.16(1-x). + 30.1

= 176/176+8

X= 0.37

0.37 × 100

X= 37%

Therefore, the percentage of excess air used during combustion process of ethane will be 37 %.
