important, especially for biological molecules?

Answers

Answer:

Structure is particularly important for biological molecules because a slight change in the structure of a large bio molecules like nucleic acids, proteins, enzymes, carbohydrates and lipid molecules can completely destroy its usefulness to a cell and may even change the cell from a normal one to a cancerous one.

You will analyze four substances in this lab. Based on their chemical formulas and what you already know about covalent and ionic compounds, make a prediction for each compound.Cornstarch, a carbohydrate consisting of hydrogen, carbon, and oxygen

Answers

Answer:

Oil: covalent

Cornstarch: Covalent

Sodium chloride: Ionic

Sodium bicarbonate: Ionic

Explanation:

Covalent compounds are formed by sharing of electrons between non metals whereas ionic compounds are formed by transfer of electrons from metals to non metals.

1. Oil, which is built from the nonmetals hydrogen, carbon, and oxygen: forms a covalent compound by sharing of electrons between non metals hydrogen, carbon, and oxygen. Covalent compounds are insoluble in water.

2. Cornstarch, a carbohydrate consisting of hydrogen, carbon, and oxygen: forms a covalent compound by sharing of electrons between non metals hydrogen, carbon, and oxygen. Covalent compounds are insoluble in water.

3. Sodium chloride (table salt), whose formula is NaCl is formed by transfer of electrons from sodium to chlorine.Ionic compounds are soluble in water.

4. Sodium bicarbonate, whose formula is is formed by transfer of electrons from sodium to .Ionic compounds are soluble in water.

Answer:

Oil, which is built from the nonmetals hydrogen, carbon, and oxygen:

If you worked at a job for 9.00/hour, what type of correlation is the number of hours worked and your take-home pay?

Answers

Answer:

There is a linear correlation between the number of hours worked and take-home pay. And more exactly, a direct proportionality. [tex]C = 9\cdot t[/tex]

Explanation:

From statement we deduce that amount of hours worked ([tex]t[/tex]) (Independent variable, measured in hours) is directly proportional to take-home pay ([tex]C[/tex]) (dependent, measured in monetary units), since proportionality ratio is constant and, therefore, there exists a linear correlation between both variables. That is:

[tex]C \propto t[/tex]

[tex]C = k\cdot t[/tex] (Eq. 1)

Where [tex]k[/tex] is the proportionality ratio, measured in monetary units per hour. If we know that [tex]k = 9\,\frac{m.u.}{h}[/tex], then the resulting correlation is:

[tex]C = 9\cdot t[/tex]

There is a linear correlation between the number of hours worked and take-home pay.

Explanation:

-------Choices  ---------------

Predict

Use variable

Plan and conduct investigations

Hypothesize

Measure

Classify and order

Record and display data

Use time and space relationships

Use numbers

=================

Selection:

These are in approximate order:

Hypothesize:  Build an explanation of the observation.  The hypothesis should be done after a thorough review of existing information.  Library database searches and researcher interviews are suggested.Predict:  prediction of what would happen if the explanation were correct.  E.g., If an atom is homogenous and has no internal structure, then bombarding it with with neutrons will result in most neutrons going right through the atom, and none would be reflected backwards.

Plan and conduct investigations:  Design experiments that test the hypothesis.  E.g., see if any neutrons are reflected backwards.  If they are, the hypothesis needs to be changed.

Measure:  Do the work.  Calibrate the equipment and record everything.

Record and display data:  Publish the results and conclusions for peer review.  Seek other's input in order to generate general agreement that the data, procedure, and conclusions are warranted.

===

Use numbers?  Nah.  Not if they are not required to reach a conclusion.(e.g., the precipitate will be pink or the reaction will stink).

Use Time and Space Relationships:  Yes, but only if the hypothesis depends on them.

Classify and Order:  OK, especially if you are a biologist, but not always necessary.

Use variable:  usually, but what and how depends on the experiment.

Blame:  Place blame on the lab partner (Just kidding).

Answers

Answer:

C is the answer..

The equation is showing how it is formed, so the answer is on the other side of the equal sign.

There are two types of chemical compound one is covalent compound and other is ionic compound, covalent compound formed by sharing of electron and ionic compound formed by complete transfer of electron. Therefore, diagram C shows the final compound.

What is chemical Compound?

Chemical Compound is a combination of molecule, Molecule forms by combination of element and element forms by combination of atoms in fixed proportion.

An ionic compound is a metal and nonmetal combined compound.  Ionic compound are very hard. They have high melting and boiling point because of strong ion bond.

Name at least three physical properties of the bowling
ball.

Answers

Answer:

The physical properties is hardness shape and color, I choose hardness because I have grabbed bowling balls before and they are very hard well there could be different types of bowling balls made of different things but I have never seen one or toughed a bowling ball that is not hard. Another physical property  I chose for the bowling ball was shape, The reason I chose shape was because the bowling ball is circle, the actual name for a 3-D circle is sphere. The last physical property for a bowling ball is color because mostly all bowling balls have color for example the one in the picture it is red with a little bit of pink, there is many different bowling balls that have different color different hardness but NOT different  shape. That is the physical properties of a bowling ball.
