Electrons attract objects and pull toward
So if the sum of the enthalpies of the reactants is greater than the products, the reaction will be exothermic. If the products side has a larger enthalpy, the reaction is endothermic. You may wonder why endothermic reactions, which soak up energy or enthalpy from the environment, even happen
Answer:
Explanation:
Because if the equation is truly balanced, the elements on one side equal the element numbers on the other. Take a simple example.
Ba(OH)2 + 2HCl ==> BaCl2 + 2HOH
Now consider what is true.
Element Number of the left Number on the right.
Ba 1 1
O 2 2
H 4 4
Cl 2 2
Nothing has changed going from the left to the right. You may wonder how you get 4 for the hydrogens.
Ba(OH)2 has 2 hydrogens. You multiply the 2 by the hydrogens in the brackets.
2HCl = The 2 in front affects both the hydrogens and the chlorines. There are 2 hydrogens from the HCl
Total: 2 + 2 = 4 hydrogens. The right side is done the same way.
You are not getting different results on the right side than those that you had on the left. Mass is preserved. 1 Ba + 2 Os + 4Hs and 2 Cls on the left, gives the same numbers on the right. There is no loss of mass.
The wavelength is the distance between one crest/trough to another crest/trough. On the image, it's basically the length between each peak of the wave. You can see that the distance between peaks in wave A are much shorter than the distance between the peaks in wave B.
Thus, wave B has the longer wavelength.
Answer:
In the unfolded polypeptide, there are ordered solvation shells of water around the protein
groups. The number of water molecules involved in such ordered shells is reduced when the protein
folds, resulting in higher entropy. Hence, the lower free energy of the native conformation.
