I think it is the gas and the heat in it
Answer:
See the image Below
Explanation:
Single C-C bonds have free rotation and thus Newman Projections are quite useful for understanding the different 3D conformations of a molecule.
For any Newman Projection you have 2 bonded carbons, one <em>in front </em>of the other, therefore you rotate the bond by rotating the groups that are bonded to the carbons. i. e. in the 2-Methylpentane <em>(viewing the C3-C4 bond)</em> the carbons chosen are the 3rd and the 4th then you look to which are the other groups bonded; <em>2 H and an isopropyl for the 3rd one, and 2 H and a Methyl for the 4th one</em>.
The different rotations of those groups receive different names:
- <em>Anti Conformation: </em>Main groups of the two Carbons are 180º apart from one another. Making this the most stable conformation of the molecule. <em>(Taking into account steric effects)</em>
- <em>Gauche Conformation: </em>Principal groups are 60º apart from each other. Since are 6 spaces between groups (360º/6)=60º. It is less stable than an Anti conformation due to the same reason.
- <em>Eclipsed Conformation: </em>The less stable conformation since the main groups are confronted.
Answer:
The hardness is more than 2.5. Hope this helps.
Answer:
Given that W=mg:
The weight of the box would be 50 N taking the value of 'g' as 10ms-2. Taking the value of 'g' as 9.8ms-2, the weight of the box would be 49 N.
(N = Newtons)
<span>We know that density is equal to mass divided by volum, D=M/V and in this case we have 1 gallon of a solution of sulfuric acid with 37.4% of concentration in mass.
1 gallon is 3785.41 ml and according the formula M=D*V = 1.31 * 3785.41 = 4958.89 grams of solution.
Only 37.4% of the solution is sulfuric acid, that is 4958.89 * 37.4/100= 1854.62 grams
Then the number of grams of sulfuric acid is 1854.62 gr.</span>
