What is the best description of bond angles around the carbon atoms of 1-butene?
vampirchik [111]

The best description of bond angles around the carbon atoms of 1-butene is double bonded unsaturated carbon atoms and sp2 hybridized

<h3>What are organic compounds?</h3>

Organic compounds are those organics substances containing carbon and hydrogen only.

Some classes of organic compounds are:

  • Alkanes
  • Alkenes
  • Alkenes

So therefore, the best description of bond angles around the carbon atoms of 1-butene is double bonded unsaturated carbon atoms and sp2 hybridized

For the equilibrium that exists in an aqueous solution of nitrous acid (HNO2, a weak acid), the equilibrium constant expression
alekssr [168]

Answer: For the equilibrium that exists in an aqueous solution of nitrous acid (HNO2, a weak acid), the equilibrium constant expression is K = [ H+] [NO2-] / [HNO2].

Explanation:

An expression that depicts the ratio of products and reactants raised to the power of their coefficients at equilibrium is called equilibrium constant.

An equilibrium constant is denoted by the symbol 'K'.

For example, the dissociation of nitrous acid in aqueous solution is as follows.

HNO_{2} \rightleftharpoons H^{+} + NO^{-}_{2}

Hence, its expression for equilibrium constant is as follows.

K = \frac{[H^{+}][NO^{-}_{2}]}{[HNO_{2}]}

Thus, we can conclude that for the equilibrium that exists in an aqueous solution of nitrous acid (HNO2, a weak acid), the equilibrium constant expression is K = [ H+] [NO2-] / [HNO2].
