Answer:
Comparison of whole genome sequences provides a highly detailed view of how organisms are related to each other at the genetic level.
Explanation:
When a material is heated, the change in temperature depends on the kind of material and its mass. Different objects can absorb and release different amounts of energy when heated and cooled. This property is called heat capacity. How might scientists apply this property to design something useful in the real world? Give one or two examples.

Fluorine + sodium chloride → sodium fluoride + __________. What is the missing chemical name?
Answer:
Chlorine (Cl)
Explanation:
The equation would be:
[tex]F+NaCl[/tex] → [tex]NaF + Cl[/tex]
This is because no atom is lost in a reaction. Chlorine would be the missing chemical as it is on the other side of the equation and needs to be accounted for on the products side.
The missing chemical in the reaction of sodium chloride with fluorine forming sodium fluoride is chlorine.
What is a chemical equation?The chemical equation is given as the representation of the reactants molecules and the product molecules in a chemical reaction.
The reaction follows the law of conservation and thereby no element will be lost in the reaction. Thus, the chemical reaction for the fluorine and sodium chloride is given as:
Fluorine + Sodium chloride → Sodium fluoride + Chlorine
Thus, the missing chemical in the reaction was chlorine.

How do I do unabbreviated electron configurations?
Answer:
In shorthand electron configuration, the electron configuration starts with the symbol of the noble gas in the previous period, followed by the additional configuration of the electrons for the given element. For example, aluminum has the atomic number 13, which is the number of protons in the nuclei of its atoms.

Back injuries can be crippling and severely limit one’s function and quality of life.
How would your life be affected by a back injury?
What modifications would you have to make to your home if you were confined to a wheelchair?
Which of your hobbies and activities would be affected if you could no longer walk?
A back injury would impact literally every aspect of your life.
You would need to either install a starlit, a lift, or move to a bungalow or bottom floor apartment.
The only hobbies you would be able to complete with no modifications would be what I call stationary hobbies- when you sit and do something, for example, knitting or sewing. However, some sports can be altered to allow for those in a wheelchair to play.
phenolphthalein is used as a visual indicator in a strong acid-strong base titration because
The pH range of phenolphthalein is 8.3 - 10.0, which is suitable with the pH range of Strong Acid and Strong base titration and so phenolphthalein is used as a visual indicator in a strong acid-strong base titration.
What is an Indicator ?Any substance that gives a clear visible indication of the presence or absence of a particular concentration of a chemical species, such as an acid or an alkali in a solution, usually by a colour change.
The pH range of Strong Acid and Strong base titration is 3–11 and equivalent point is at 7
the pH range of Strong Acid and Weak base titration, is 3–8 and equivalent point is below 7
the pH range of Weak Acid and Strong base titration, is 6 - 11 and equivalent point is above 7
So for titration , an indicator with suitable pH range is used
The pH range of phenolphthalein is 8.3 - 10.0.
Therefore phenolphthalein is used as a visual indicator in a strong acid-strong base titration.

Most lakes have rivers flowing out of them, carrying water to the ocean. However, some
lakes, including Great Salt Lake and the Dead Sea, have no outlet. Water flowing into
these lakes leaves only through evaporation. Considering that the water flowing into the
lakes contains many dissolved substances, how does the lack of an outlet affect the
composition of these lakes? What would you expect to happen after many more years
of inflow and evaporation?

Because heating and cooling can be done by an AC unit, which takes electricity. Communication also takes electricity, along with lighting (especially if we're talking light fixtures to light up homes). Not to mention motion, such as cars and other transportation uses, believe it or not, electricity.

list 5 chemical properties of water??
Answer:
In the presence of a strong electron donor (strong reducing agent), water serves as an oxidizing agent. In the presence of a strong electron acceptor (strong oxidizing agent), water serves as a reducing agent. On-water reactions are a group of organic reactions that take place as an emulsion in water and have an unusual reaction rate acceleration compared with (i) the same reaction in an organic solvent, or (ii) the corresponding dry media reaction.Amphoteric nature : Water can act as both acid and base, which means that it is amphoteric in nature.Hydrolysis reaction : Water has a very strong hydrating tendency due to its dielectric constant. It dissolves many ionic compounds. Some covalent and ionic compounds can be hydrolyzed in water.Redox reactions : Electropositive elements reduce water to hydrogen molecule. Thus, water is a great source of hydrogen.Are two atoms of same element identical
Answer:
No. Two atoms of the same chemical element are typically not identical. Since the states of the electrons in an atom are what determine the nature of the chemical bonding that the atom experiences, two atoms of the same element can react differently if they are in different states.
Answer: No
Explanation: Two atoms of the same chemical element are typically not identical. First of all, there is a range of possible states that the electrons of an atom can occupy. Two atoms of the same element can be different if their electrons are in different states.
