Water is a polar molecule because of its shape
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.

Answer:
Explanation:5,2 methyle- dhexene
You just need to convert it into moles per Liter (mol/L).
0.0815mol / 0.550L = 0.148mol/L
Answer:
C2H3O2
Explanation:
Empirical formula is defined as the simplest whole-number ratio of atoms present in a molecule. To solve this question we need to convert the percentage of each atom to moles using molar mass. With the moles of each atom we can find the ratio:
<em>Moles C -Molar mass: 12.01g/mol-</em>
40.68g * (1mol/12.01g) = 3.387 moles C
<em>Moles H-Molar mass:1g/mol-:</em>
5.12g * (1mol/1g) = 5.12 moles H
<em>Moles O -Molar mass: 16g/mol-</em>
54.19g * (1mol/16g) = 3.387 moles O
Ratio of atoms (Dividing in moles of C that are the lower number of moles):
C = 3.387 moles C / 3.387moles C = 1
H = 5.12moles H / 3.387moles C = 1.5
O = 3.387moles O / 3.387 moles C = 1
This ratio twice (To have only whole-numbers):
C = 2
H = 3
O = 2
