Answer: Equilibrium concentration of CO=0.014M  

Equilibrium concentration of Cl_2=0.037M  

Equilibrium concentration of COCl_2=0.135M  

Explanation:

Initial concentration of CO=0.1490M  

Initial concentration of Cl_2=0.172M  

The given balanced equilibrium reaction is,

                            CO(g)+Cl_2(g)\rightleftharpoons COCl_2(g)

Initial conc.         0.1490 M        0.172                 0

At eqm. conc.    (0.1490-x) M   (0.172-x) M   (x) M

The expression for equilibrium constant for this reaction will be,

K_c=\frac{[COCl_2]}{[Cl_2]\times [CO]}

255=\frac{x}{(0.1490-x)\times (0.172-x)}

x=0.135

Equilibrium concentration of CO=(0.1490-x)M= (0.1490-0.135)=0.014M  

Equilibrium concentration of Cl_2=(0.172-x)M= (0.172-0.135)=0.037M  

Equilibrium concentration of COCl_2=0.135M

Nataly [62]

Answer:

2:8

Explanation:

The reaction equation is a given as:

         2C₄H₁₀   +    130₂   →    8CO₂     +     10H₂O  

From the reaction equation, the mole ratio is 2:8

Butane is C₄H₁₀

Carbon dioxide CO₂

From the reaction;

       2 moles of butane will produce 8 moles of carbon dioxide

Nataly_w [17]

Answer:

V2 = 894.4mL

Explanation:

P1= 124.1, V1= 578mL, P2 = 80.2kPa, V2= ?

Applying Boyle's law

P1V1 = P2V2

Substitute and simplify

124.1*578=80.2*V2

V2= 894.4mL

Which of the following has a melting point greater than room temperature?
nikdorinn [45]
Technically, the answer is iron. Oxygen has a melting point way below zero (-219 degrees celsius), ice becomes water AT room temperature and bromine is already a liquid at room temperature. So, iron has a melting point greater than room temperature due to the fact that metals are made up of giant structures of atoms in a regular arrangement, and there are strong forces of electrostatic attraction between positive metal ions and negative electrons, meaning that a lot of heat energy is required to break the bonds, i.e. a very high melting point, approx. 1500 degrees celsius. Hope this helps.

Tpy6a [65]
In the combustion process using excess oxygen, each mole of methane results to 1 mole of co2 while ethane produces 2 moles of Co2. Under same conditions, these can be translated to volume. Hence the total volume absorbed is 10 cm3 + 20 cm3 = 30 cm3.
