Answer:
See image attached
Explanation:
Ibuprofen is a chiral compound. 'Chiral' means that it has the ability to rotate plane polarised light owing to the presence of an asymmetrically substituted carbon atom. There are two known stereoisomers of the compound; the S- stereoisomer and the R-stereoisomer. The both are shown using wedge and dash perspectives in the image attached.
Only the S- stereoisomer is active as a drug. The R-stereoisomer is gradually converted into the S-stereoisomer in the body. The drug may also be given as a racemic mixture.
They are all biotic factors, meaning they were once alive or were alive. (an abiotic factor is something that has never lived.) hope this helped.
Answer:
B. Extreme heat and pressure.....
Explanation:
This is how sedimentary rocks are actually made. I had learned recently in my class about these rocks, and my teacher told that these are made by heat and pressure. And these are the types of rocks that you'll find in canyons for example Grand Canyon.
You know that when something gets pressurized then it changes shape, same for rocks, if they're having lots of pressure on them, then they will also basically turn into newer rocks and also change shape. They also change looks because sedimentary rocks don't look like any other type of rock.
Also, heat can also be found in the crust of the earth since there is the Mantle under the crust which is filled up of MAGMA! (supa hot magma!! woohoo!) And also, because all of the dirt and stuff underground is packed together, the friction can also create heat. As you know, heat makes things expand, you might have done this before.... when you learned about hot and cold gas, you might have also learned that hot gases are more larger, and require more volume than cold gas. That means that the size of the object changes, that too, it's not just for gas, it's for everything, <em>including rocks!</em>.
Hence, your answer is B. Extreme heat and pressure from inside the earths surface......

Have a great day!
Answer:
1. False 2.True3.True? Unsure
Explanation:
The balanced reaction is:
<span>Cu + 2AgNO3 = 2Ag + Cu(NO3)2
We are givent the amount of silver to be produced. This will be the starting point. Calculations are as follows:
</span><span> 3.50 mol Ag ( 1 mol Cu / 2 mol Ag ) = 1.75 mol Cu
</span>
Therefore, we need 1.75 mol of copper in order to produce 3.50 mol of silver.
