Answer:
In chemistry, the mole is a unit used to talk about atoms. It is similar to other units we use everyday. For example, you might walk into the local doughnut shop and order a dozen doughnuts. In doing so, you know that you will get 12 of these snacks and the clerk knows to give you 12.
xplanation:
A line shows a bonding pair of electrons (which are usually 2 for every line) – the atoms involved in the bond share two electrons per bond to form a covalent bond. The two dots show a pair of lone electrons NOT involved in bonding.
The Carbon and Sulfur will require to have their valence orbital shell involved in the bonding to have 8 electrons. The Hydrogens need 2 to achieve stable electron configuration. This way the atoms achieve stability in the molecule
<span>the ionization constant, Ka, for and indicator, HIn, is 1.0x10^-8. The color of the unionized form is red and the color of the ionized form is yellow. What is the color of the indicator in a solution whose pH is 4.6? (Hint: the color of an indicator can be estimated by considering the ratio of [HIn]/[In]. If the ratio is equal to or greater than 10, the color will bet hat of the unionized form. If the ratio is equal to or smaller than 0.1, the color will be that of the ionized form.
</span><span>Ka=[H+][A-]/[HA]
substitute for pH and find the value of A-/HA.
</span><span>
</span><span>so it'd just be 1x10^-8 divided by 4.6</span>
