Answer:
68 grams
Explanation:
Reaction that produces ammonia when nitrogen and hydrogen reacts is given by :-
+ 3 → 2N
Clearly ,
When one mole of nitrogen reacts , two moles of ammonia will be produced.
Now,
weight of 1 mole of the Nitrogen = 28.0 grams
In 56.0 grams of the nitrogen , two moles will be present.
Thus , 4 moles of ammonia will be produced .
Weight of one mole of nitrogen = 17 grams.
Thus a total of 17× 4 = 68 grams f nitrogen will be produced.
The enthalpy of this reaction is -5315 KJ/mol.
The equation of the reaction is;
2C4H10(g) + 13O2(g) -----> 8CO2 (g) + 10H2O(g)
We know that the enthalpy of reaction can be obtained from the enthalpy of formation of the reactants and products as follows;
ΔHrxn = ΔHf(products) - ΔHf(reactants)
We have the following information from the question;
ΔHf C4H10 = - 125. 6 kJ/mol
ΔHf CO2 = - 393. 5 kJ/mol
ΔHf H2O = - 241. 82 kJ/mol
ΔHf O2 = 0 KJ/mol
Hence;
[(8 × (- 393. 5 )) + (10 × (- 241. 82))] - [2( - 125. 6))]
= -5315 KJ/mol

Answer:
in the presence of water, a strong acid will dissociate quickly and release heat, so it is an exothermic reaction.
Explanation:
Membranes provided significant advantages for the survival of organisms and the replication of their genetic material.
One significant advantage was the ability to better regulate and insulate the cells internal environment from the external environment. The cell had better control over the chemical composition and temperature inside its membrane, which made it easier to survive.
Cells with membranes were able to contain their genetic material, ensuring that, when replicated, it was identical to the parent cell. This meant that organisms with better survivability traits passed on their genetic material in a way that better preserved their genes, and by extension these advantageous traits.
These advantages helped cells with membranes to better survive and replicate, and also enabled the more complex cells with advantageous genetic material to better preserve and copy that material to new cells, allowing for a higher probability of reproduction among more complex life forms.
