What is the elevation of point B?

Chemistry
1 answer:
kakasveta [241]3 years ago
7 0
It is located about half-way between the 20 feet contour line and the 30 feet contour line. For this reason, the elevation of point B must be somewhere in between 20 and 30 feet.

To what volume must 175 L of air at 1.0 atm be compressed to yield a pressure of 5.2 atm? (You can assume constant temperature.
Elena L [17]
Using the ideal gas law, for a constant temperature, pV = constant (also known as Boyle's Law)
(1 atm)(175 L) = (5.2 atm)(V) = constant
V = 33.7 L

Choose the TRUE statement.

Mass is calculated by using an objects inertia. Since inertia is a quality of matter that resists motion, we can apply an increasing force to an object until it accelerates.

Then, by measuring its acceleration we can now determine its mass using the simple equation F=m×a, except rewritten as m=Fa.

So we divide the force that we applied by the acceleration rate and we get the objects mass.

Without inertia this cannot be done.


∴ Answer is C

What is the best name for this molecule? Explain your naming process. I myself just cannot figure it out. I deeply appreciate an
IrinaK [193]
It seems like I begin to forget whole organic Chemistry. Anyway, the answer is 2-methylheptane-3-yne.
To build a name for this molecule, you need to:
1. Determine where there is the lowest chain beginning with the double, triple bond, or there is other thing for other types of organic molecules.. In this case you have one triplet bond, and the lowest chain there is the one that is below the bond.
2. In this small chain you see one "forks": CH3 and another CH3 go from the one CH. Put number 1 where there are the most number of such compounds, in this case it doesn't matter because we have one CH3 in one way and one CH3 in the another.
3. Determine the largest chain which surely has the triple bond. Put the numbers from 2 to the final beginning with CH3 where you put number 1. Your largest chain consists of 7 particles CH3, CH2, and CH.
4. You see that you also have one unnamed particle, the one which is "the other way" when you are in the CH which is below the triple bond on the picture. Its name will be 2-methyl because it is connected with particle #2 and it consists only of one carbon. If there were 2, it would be ethyl, and so on.
5. Finally, let's write a full name: put 2-methyl first, "2-methyl." Then, write a full name for the chain of 7 carbons, which has to be heptane, if it had 5, you would name it pentane, ethane, and so on. So, we have "2-methylheptane." Finally, you see that you have a triple bond after the carbon #3. Put a dash and the number of this carbon. "2-methylheptane-3" you should have. Since it is alkyne (organic molecule with one triple bond), you have to write "yne" at the end.
the final name is "2-methylheptane-3-yne." You can answer the question "explain your naming process" by using the answer I provided. Hope it helps. Good luck!
