Louie drinks a bottle of a water even though he is not thirsty. As a result, what will the body do to maintain homeostasis?
drek231 [11]
<span>Having too much water in the body could cause so much complications; just as having too little can be dangerous. In each of these scenarios the body tries to maintain equilibrium through a process called homeostasis. Homeostasis depends on many variables, such as body temperature and body fluid being kept within certain pre-set limits. The essence of homeostasis is maintain bodily functions and metabolism at equilibrium state. If Loiue takes in so much water in a very hot atmosphere or during summer even though he's not thirsty, his body would have to get rid of the excess water by sweating. On the other, during winter, or in a cold environment Loiue's body would have to get rid of excess water by urinating frequently.</span>

Do you notice a pattern in the charge for elements in each group? Explain.
MrRissso [65]

Answer:

Below are some patterns in the charge for elements in each group.

Group 1 elements : 1 valence electron and form ions with charge +1

Group 2 elements : 2 valence electrons and form ions with charge + 2

Group 3 elements : 3 valence electrons and form ions with charge + 3(there are some exceptions as well)

Elements in groups 4 and 5 are unpredictable also the D block elements consist of multiple oxidation states..

Group 6 elements : 6 valence electrons, form ions with charge -2

Group 7 elements: 7 valence electrons, form ions with charge -1  

The octet rule is being followed, the elements form either ionic bond or covalent bond to fulfill it.

eg: when a K atom forms a K+ ion, the ion has the same electron configuration as the noble gas Ar (argon).

When an O atom gains 2 electrons to form the O²⁻ ion, the ion has the same electron configuration as the noble gas Ne (neon).  

Note: Boron (B) is in Group 3 but doesn't form ions.

What is the Law of the Conservation of Mass
Fantom [35]

Answer: law of conservation of matter states that mass in an isolated system can neither be created nor destroyed by chemical reactions or physical transformation.

thus, the mass of the reactants in a reaction must be equal to the mass of the products
