Im so sorry i don’t know I just need to answer 2 questions for me to be Able to ask
Answer:
The ΔHrxn for the above equation = 179 kJ/mol
Explanation:
The reaction bond enthalpies are for the reactant;
3 × N-H = 3 × 390 = 1,170 kJ/mol
2 × O=O = 2 × 502 = 1004 kJ/mol
The reaction bond enthalpies are for the product;
3 × N-O = 3 × 201 = 603 kJ/mol
3 × O-H = 3 × 464 = 1,392 kJ/mol
The ΔHrxn for the above equation is therefore;
ΔHrxn = 1,170 + 1,004 - (603 + 1,392) = 179 kJ/mol
Answer: It is an unsaturated solution
Explanation: This is because it has more solute than a normal solution.
Answer:
a. 4 sig figs
b. 3 sig figs
c. 2 sig figs
Molecular data is more informative than morphology because this examines the DNA sequence and protein composition. This then provide a more comprehensive detail on what species are more related and distant with one another. .
