The correct answer is A. Charging by friction
Explanation
When someone rubs a comb with their hair when they are combing it and the hair sticks to the comb occurs a phenomenon called electrization, in which a neutral body becomes charged or loses an electrical charge (electrons). One way that electrization occurs is through the rubbing of two neutral bodies which causes one to be positively charged and the other negatively causing them to attract each other by magnetism. Therefore, the correct answer is A. Charging by friction
The transition metals are 10 columns wide because they can hold no more than 10 electrons. This is why their width correlates with the number of electrons that are included in these metals. Transition metals include most commonly used metals, such as iron, copper, silver, and gold.
Answer:
eukaryotic because it has a nucleus
Explanation:
Neutralization reaction takes place between an acid and a base to form salt and water.
In the given reaction the acid is hydrochloric acid HCl and the base is aluminum hydroxide (Al(OH)
).
The correct balanced equation for the neutralization reaction that occurs between aluminum hydroxide and hydrochloric acid can be represented as:
Al(OH)can give 3 hydroxide, 
ions which can neutralize the 3 
ion produced by 3 HCl molecules giving 3 mole of water and the salt aluminum chloride, AlCl.
Therefore the correct option will be.
D. Al(OH)3 + 3 HCl (aq) --> AlCl3(aq) + 3 H2O(l)
Answer:
The three basic types of clusters astronomers have discovered are globular clusters, open clusters, and stellar associations. ...
Globular clusters were given this name because they are nearly symmetrical round systems of, typically, hundreds of thousands of stars. ...
Open clusters are found in the disk of the Galaxy.
