Explanation:
AH is negative because the reaction gives out heat (exothermic).
AS is negative because the total entropy of the reactants is greater than that of the products (there are 4 moles of gas on reactant side compared to only 1 mole on the product side). Thus, the reactants are said to be "messier" than the products.
AG is negative at lower temperatures because at low temperatures, -TAS is more negative, resulting in the negative sign of AG.
Hope this helps.
Both the atoms are of the same element but one of them is electrically neutral and the other has a stable electronic configuration.
<h3>What is the meaning of a neutral atom?</h3>
An atom is said to be neutral because it has an equal number of electrons and protons in it.
If two different atoms have nine protons each and the same mass but one is neutral while the other has a negative charge.
This implies both the atoms have the same nucleus but different charges so it can be concluded that they are both the atoms of the same element but one of them is electrically neutral and the other has gain electron from other element and have stable electronic configuration.

Smaller atoms and stronger bonds promotes greater hardness in minerals.
Explanation:
The retention of analytes in gas chromatography can be increased by selecting mobile phase that is a weaker solvent. When the mobile phase has a lower solvent strength, solutes spend proportionally more time in the stationary phase and take longer to elute.
