Explanation:
Explanation:
a. Write the molecular formula of the compound.
Acetaminophen contains 8 carbon atoms, 9 Hydrogen atoms, 1 Nitrogen atom and 2 Oxygen atoms.
The molecular formular is given as; C8H9NO2
b. What is the hybridization state of each C, N, and O atom?
From the image attached;
All the carbon atoms in the benzene ring has hybridization of sp2.
The carbon that is doubly bonded (carbonyl) to the oxygen has hybridization of sp2
The last carbon to the right has hybridization of sp3
The hybridization of nitrogen in the compound is sp3 hbridized.
Oxygen atom in alcohol is sp3 hybridised
Oxgen in the carbonyl group is sp2 hybridized.
By dissolving salt in seawater the seawater acts as the solvent. The definition of a solvent is: liquids that dissolve other substances.
Sodium chloride , commonly known as salt (although sea salt also contains other chemical salts), is an ionic compound with the chemical formula NaCl, representing a 1:1 ratio of sodium and chloride ions. With molar masses of 22.99 and 35.45 g/mol respectively, 100 g of NaCl contains 39.34 g Na and 60.66 g Cl.
Answer:
ΔH = - 272 kJ
Explanation:
We are going to use the fact that Hess law allows us to calculate the enthalpy change of a reaction no matter if the reaction takes place in one step or in several steps. To do this problem we wll add two times the first step to second step as follows:
N2(g) + 3H2(g) → 2NH3(g) ΔH=−92.kJ Multiplying by 2:
2N2(g) + 6H2(g) → 4NH3(g) ΔH=− 184 kK
plus
4NH3(g) + 5O2(g) → 4NO(g) +6H2O(g) ΔH=−905.kJ
__________________________________________________
2N2(g) + 6H2(g) + 5O2(g)→ 4NO(g) + 6H2O(g) ΔH = (-184 +(-905 )) kJ
ΔH = -1089 kJ
Notice how the intermediate NH3 cancels out.
As we can see this equation is for the formation of 4 mol NO, and we are asked to calculate the ΔH for the formation of one mol NO:
-1089 kJ/4 mol NO x 1 mol NO = -272 kJ (rounded to nearest kJ)
