Metallic bonds are responsible for many properties of metals, such as conductivity. Why is this possible? (1 point)
Maksim231197 [3]

The correct answer is;  Metals have low electronegativity, so they are conductive because they pass charges easily.

Metals are found towards the left hand side in the periodic table. They are known for their low electronegativity. Metals are electropositive. This means that they loose charges(electrons) easily.

A metallic bond is comprised of positively charged metallic ions and a sea of electrons.These electrons can move freely.

This sea of electrons are the charges that are responsible for the properties of metals such as high conductivity.

1A):  Fats are  =====>     <u>Solid at Room temperature</u>

1B):   Oils  are    =====>  Liquid at Room Temperature


2A):  Lipids ====> <u>Are a group of organic compounds, that include fats, oils, waxes and related substances. Lipids are composed of carbon and hydrogen, and oxygen, but there is no definite ratio of hydrogen to oxygen atoms lipids as there is in  carbohydrates. Simple lipids, which are the most  common type, are made up of three fatty acids molecules, and glycerol molecule.</u>


2B):  Carbohydrates  =====> <u>Are organic compounds composed of carbon, and hydrogen, and oxygen. The proportion of hydrogen atoms to oxygen atoms in carbohydrates is the same as in water; Two hydrogens to one oxygen. There are three basic types of carbohydrates. Monosaccharides, disaccharides, and polysaccharides.</u>


3): <u>A positive control ===> s</u><u>hould give the desired outcome of the experiment, provided that all the reagents and equipment are functioning properly. For example, if your experiment results in the ability of bacteria to grow on a petri plate containing antibiotic, your positive control will be bacteria that are known to carry the appropriate drug resistance marker. Even if none of your experimental bacteria grow, as long as there is growth of the positive control you know that growth was possible.  </u>

3B):   A Positive Control  =====> <u>should be designed to not give the desired outcome of the experiment. In the example above, bacteria which do not carry a drug resistance marker should not be able to grow on a petri plate containing antibiotic. If growth is observed, it is a red flag that something is wrong with the experiment.</u>




Hope that helps!!!                                  : )
