No icicles are water made up of atoms not cells
Answer:
B) increases
higher temperature = higher pressure
The Newman projection gives the view of the molecule. In molecule A the torsional strain and in B steric strain are present because of the gauche methyl group.
<h3>What is a torsional strain?</h3>
The Newman projection depicts the molecules in the head-on view and uses the letters and the lines to represent the molecule. The torsional strain is because of the molecule's resistance to the twisting.
The steric strain is the Vander wall strain that is due to the forced interaction of the molecules separated by covalent bonds resulting in molecular potential energy.
The diagram for the question is attached below.
Therefore, the correct blanks are <u>torsional</u>, <u>steric</u>, and <u>gauche</u>.

Answer:
If Thomson's atomic theory was accurate, the positively charged particles would have gone through the foil.
Here are the steps for finding an emprical formula.
To begin, we need to change the grams to a percentage. We can simply take the number and call it our percentage. (i.e 0.262%)
Then, we have a simply stoichiometry step. We put our starting number over 1, as usual. The next "Step" is putting in the molar mass of that particular element on the bottom, with one on top. It should look like this:
0.262% N 1
-------------- x ----------------
1 14.007g N
We would then divide those two numbers to get our answer. Repeat for the other elements included, until we have all of them done.
After that, we need to find the smallest number that was the answer to one of the equations. For example, if the product of Hydrogen was the smallest formed, we would locate that number. We then divide ALL of our answers by that smallest number.
Remember, whenever doing empirical formulas, significant figures matter.
Once we have our smallest numbers, we need to round our numbers to the nearest whole number. HOWEVER, to do this we need to multiply all of the numbers by the SAME whole number.
For example, if one of our numbers was 1.33, we would multiply by 3 to get a whole number. However, we would also need to multiply the rest of our products by the same number. If we do not get close to whole numbers (you can round), we need to try with multiplying a different number.
Then, we need to take those whole numbers we got for each number, and plug in to make a compound. For example, if our products were 6 for nitrogen, 3 for hydrogen, and 2 for chlorine, our final empirical formula would be N6H3Cl2.
Hope I could help! If it was a bit wordy please let me know and I'd be more than willing to clarify.
