Answer:
1. Magnesium and oxygen atoms bond to form an ionic compound; this is evident because one forms a cation and the other an anion. When an ionic compound is formed, one atom "steals" an electron (or electrons) from another. In this case, an oxygen atom (which is pretty electronegative by the way) "steals" 2 electrons from a magnesium atom. The resulting oxygen anion and magnesium cation attract one another to form a bond (more specifically, an ionic one).
2. The oxygen atom needed two sodium atoms to bond because it needs two additional electrons to achieve a stable octet of electrons. 1 sodium atom provides 1 additional electron after it is "stolen" by oxygen, so 2 sodium atoms are needed in total to form the bond.
3. The magnesium atom needed two fluorine atoms to bond because it needs to lose two electrons to achieve a stable configuration/octet of electrons. 1 fluorine atom "steals" one electron, so 2 are needed in total.

<span>In the sentence "Biologists recognize the following levels of cell organization: _____, the choice that correctly completes the sentence is b. cellular, tissue, organ, system, and organism. A cell is the basic unit of living organisms. The group of similar cells that work together to perform a specific job is a tissue. The group of multiple tissues joined together in the functional structure is an organ. Functionally related organs form organ systems, which all together form one organism.</span>
Answer: Burping (also known as "belching" or "eructation") is one way the human body expels excess gas in your digestive system. It occurs when your stomach fills with air, which can be caused by swallowing food and liquids. Drinking carbonated beverages, such as soda, is known to increase burping because its bubbles have tiny amounts of carbon dioxide in them.
As an avid soda drinker and statistics student, you notice you tend to burp more after drinking root beer than you do after drinking cola. You decide to determine whether there is a difference between the number of burps while drinking a root beer and while drinking a cola. To determine this, you select 20 students at random from high school, have each drink both types of beverages, and record the number of burps. You randomize which beverage each participant drinks first by flipping a coin. Both beverages contain 12 fluid ounces.
