The molecules vibrate when the substance is heated, and the shape of the substance begins to form a different shape. For example: when you hear up metal it will melt becuase its molecules are changing and moving.
Bonds formed between atoms can be classified as ionic and covalent
Ionic bonds are formed between atoms that have a high difference in the electronegativity values.
In contrast, bonds formed between atoms that have a difference in electronegativity lower than the ionic counterparts are polar covalent bonds. If the atoms have very similar electronegativities, they form non-polar covalent bonds.
In H2S, the S atom is bonded to 2 H atoms. The electronegativity of H = 2.2 and S= 2.56. Since the difference is not high the bond formed will be covalent (polar covalent).
Answer : The value of
of this reaction is, 
At equilibrium, [L-malate] > [oxaloacetate]
Explanation :
The relation between the equilibrium constant and standard Gibbs free energy is:

where,
= standard Gibbs free energy = +30 kJ/mol = +30000 J/mol
R = gas constant = 8.314 J/K.mol
T = temperature = 
= equilibrium constant = ?
The given reaction is:




Therefore, the value of
of this reaction is, 
As, the value of
< 1 that means the reaction mixture contains reactants.
At equilibrium, [L-malate] > [oxaloacetate]
By changing the number of protons in an element, you are fundamentally changing it to a different element.
It’s worth remembering that:
Protons identify the element
Electrons determine properties and behavior of the element
Neutrons contribute to isotopes and just help keep everything stable, by separating the charges. Remember opposites attract. Like charges repel.
