Express the equilibrium constant for the combustion of ethanol in the balanced chemical equation. C2H5OH(g)+3O2(g)⇌2CO2(g)+3H2O(
Bogdan [553]

Answer:

The correct answer is C where K=[CO2]^2[H2O]^3/[C2H5OH][O2]^3

Explanation:

Equilibrium constant (K) is expressed as the product of all the products divided by the product of all reactants. the coefficient in front of each reactants or products are used as their exponents. Solids and liquids are considered to be 1 hence they are not shown, but in this case everything is in gaseous form thus they are all expressed in the equilibrium formula formula.

Draw the alkyne formed when 2,3-dichloropentane is treated with an excess of strong base such as sodium amide.
Xelga [282]
Hi! Thank you for posting your question here at Brainly. I hope I would be able to help you with my answer.

When an alkyne such as 2,3-dichloropentane is treated with excess sodium amide, a two-step elimination reaction will happen. The reaction would then yield the final product in the form of 2-pentyne. Its structure is shown in the attached image.

Which of the solutions below is a weak electrolyte? nacl(aq) koh(aq) hcl(aq) h2so3(aq) all of these?
Deffense [45]

Answer:-

H2SO3 (aq)

Explanation:-

NaCl, KOH and HCl ionic compounds.

Ionic compounds dissociate into ions in water.

Ions can carry electricity in water. So NaCl, KOH and HCl are all strong electrolytes.

H2SO3 is not a strong acid and dissociates to a small extent into ions in water.

Hence number of ions formed is less. Hence it is a weak electrolyte.
