N2 + 3H2 -------> 2NH3
G is always positive when enthalpy increases and entropy decreases.
Well 6Na + N2 > 2Na3N
2nh4no3 ---> 2n2 + o2 + 4h2o
If you mean valence shell electrons, yes. Alluminum an Nitrogen are exelent examples. If you mean triple bonds examples are carbon in alkynes, e.g. ethyne (acetylene and nitrogen in N2 The triple bonds consist of a a sigma bond and two pi bonds and therefore have three shared pairs.
N2 its an element in its natural state
Delta S represents the change in entropy of a system. In the equation delta G = delta H - T delta S, it is used to determine the contribution of entropy to the overall change in Gibbs free energy. A negative delta S value suggests a decrease in the disorder of a system.
The change in enthalpy between products and reactants in a reaction
To determine the delta H of a reaction, one can use calorimetry to measure the heat released or absorbed during the reaction. This involves measuring the temperature change of the reaction mixture and using it to calculate the heat exchanged. The delta H value represents the change in enthalpy of the reaction.
Yes
To reverse a reaction in a Hess's Law problem, you must take the negative of the enthalpy change (( \Delta H )) for that reaction. If the original reaction has an enthalpy of ( \Delta H ), then the enthalpy value you would use for the reversed reaction as an intermediate would be (-\Delta H). This ensures that the direction of the reaction is correctly accounted for in the overall calculation.

Delta H represents the change in enthalpy of a system. In the equation ΔG = ΔH - TΔS, it is the enthalpy change of the system. It indicates the heat absorbed or released during a reaction at constant pressure.
The change in enthalpy between products and reactants in a reaction
The expression n2 + h2 + nh3 is the sum of the squares of two numbers n^2 and h^2, along with the product of n and h multiplied by 3.
Q is equal to delta H in a chemical reaction when the reaction is at constant pressure and temperature.
