Complete equation, ionic equation, and net ionic equation for NH4C2H3O2(aq) + NH3 (aq)
Answer:
The correct option is;
D)
Explanation:
The given reaction is presented as follows;
NH₄Cl (s) → NH₃ (g) + HCl (g) ΔH° = 176 kJ/mol, ΔS° = 0.285 kJ/(mol·K)
We note that the Gibbs free energy, ΔG° is represented by the following equation;
ΔG° = ΔH° - T·ΔS°
Where:
T = Temperature (Kelvin)
The reaction will be spontaneous for exergonic reactions, ΔG° < 0 and it will not be spontaneous for endergonic reaction, ΔG° > 0
At room temperature, T = 25 + 273.15 = 298.15 K
Which gives;
ΔG° = 176 - 298.15 × 0.285 = 91.03 kJ/mol which is > 0 Not spontaneous reaction
At 800°C, we have;
T = 273.15 + 800°C + 1073.15 K
ΔG° = 176 - 1073.15 * 0.285 = -129.85 kJ/mol which is < 0 the reaction will be spontaneous
The correct option is therefore, that at room temperature, the reaction is not spontaneous. However, at high temperatures. like 800 °C, the free energy value turns negative and this reaction becomes spontaneous.
As mentioned, this is a trial-and-error process. I typed in the Avogadro's number 6.022×10²³ then added the largest number I could think of. Since infinity can be thought of as 99999...(and so on), I thought that the number should all be composed of 9. As I add 9 after one another, I ended with about 10 quadrillion before the display changed to 6.022000001×10²³. Therefore, the largest number is: 9,999,999,999,999,999.
there are seven continents. hope I helped!
here they are: Africa, Antarctica, Asia, Australia/Oceania, Europe, North America, and South America
Answer:
No, because the number of carbon, hydrogen & oxygen atoms on both sides of the equation are not equal.
Explanation:
For an equation to be completely balanced, there should be equal number of reactants and products.
Number of carbon atoms on reactant side = 16
Number of hydrogen atoms on reactant side = 16
Number of oxygen atoms on reactant side = 50
Number of carbon atoms on product side = 8
Number of hydrogen atoms on product side = 36
Number of oxygen atoms on product side = 34
Therefore, we can conclude that total number of reactants does not equal total number of products therefore, this equation is not completely balanced.
