Answer:
Boron family.
Explanation:
Group 13 is called boron family.
It consist of five members boron, aluminum, gallium, indium and thallium.
Boron is semi metal while other members are metals.
Boron hydrates are used to make organic compounds.
Al is soft metal and aluminum oxides are widely used as thermal insulator.
Aluminum sulfate is also very important commercial compound used in sizing paper.
Gallium is also very important element of this group. It form gallium arsenide which is used to convert the light into electricity.
Indium is malleable soft metal which is used in optical instruments.
Thallium is highly toxic and for the long period of time it as used as insect killing poison.
Acetic acid, phosphoric acid, hydrochloric acid.
sodium bicarbonate, magnesium hydroxide, aluminum hydroxide
calcium carbonate, sodium bicarbonate, magnesium sulfate.
A student compares the boiling point of substances having different intermolecular forces. <u>Boiling points of various substances</u> is the dependent variable that student most likely use.
<h3>Does the nature of intermolecular forces present in different substance affect their boiling points?</h3>
The boiling point of a substance is proportional to the strength of its intermolecular forces, the higher the boiling point, the stronger the intermolecular forces. We can compare the strengths of intermolecular forces by comparing the boiling points of different substances.
<h3>What properties are affected by intermolecular forces?</h3>
Intermolecular forces are measured by boiling points.
Intermolecular forces increase as bond polarization increases.
Ionic > hydrogen bonding > dipole dipole > dispersion is the order of the strength of intermolecular forces (and thus their impact on boiling points).
<h3>How can you determine strong and weak intermolecular forces?</h3>
Substances with strong intermolecular forces are very attracted to one another and are held together tightly. These substances require a great deal of energy to separate, whereas substances with weak intermolecular forces are held together very loosely and have weak interactions.
