First convert to moles:
0.5113 g / 17 g/mol = 0.0301 mol
Now create a ratio based on the reaction provided to solve for the unknown:
4 NH3 / -905.4 kJ = 0.0301 mol NH3 / x kJ
x = -6.808 kJ
The pairing that accurately matches a bio molecule polymer with its monomer subunit would be B. Protein and amino acids.
The second thesis statement is perfect. It supports the claim and presents main idea.
The molar concentration will be greater than 0.01 M
.
Since more of the compound was measured out than what was calculated, you can think of the solution as being 'stronger' than what it was calculated to be. Since a 'stronger' concentration results in a number that is higher, the molarity of this solution is going to be greater than 0.01 M.
