Chemistry

fomenos4 years ago
8 0

A. The number of valence electrons determines how it reacts with other elements.

<em>One to three valence electrons</em>: The element behaves like a metal and reacts with non-metals.

<em>Five to seven valence electrons</em>: The element behaves like a non-metal and reacts with metals.

<em>Four valence electrons</em>: Elements at the top of the Group are non-metals, while those at the bottom are metals.

<em>Eight valence electrons</em>: Elements have a complete octet, so they are generally unreactive.

The following reaction: HF(aq) &lt;--&gt; H+(aq) + F-(aq) has an equilbirum constant (K) value of 7.2 x 10-4. This means that th
andriy [413]

Given an equilibrium constant value of 7.2 x 10-4 it is false to say that the reaction proceeds essentially to completion.

<h3>What is the equilibrium constant?</h3>

In a reaction, we can judge using the value of the equilibrium constant weather or not the reaction moves on to completion. If the reaction moves up to completion, it the follows that the value of the equilibrium constant ought to be large.

On the other hand, when we have a case that the equilibrium constant is small and is not so large, then the reaction does not proceed essentially to completion.

Given an equilibrium constant value of 7.2 x 10-4 it is false to say that the reaction proceeds essentially to completion.
