Answer:
some bonds are broken and new ones are formed. Now you are ready to learn more about those bonds. Chemical bonds are attractions between atoms. They are simply attractive forces (between the + nucleus of one atom and the - electrons of a neighboring atom) that hold groups of atoms together and make them function as a unit.

Answer:
88.1 moles of H₂
Explanation:
Let's make the reaction:
H₂(g) + CO₂(g) → H₂O(g) + CO(g)
Ratio is 1:1
Therefore, 1 mol of hydrogen reacts with 1 mol of carbon dioxide to produce 1 mol of water and 1 mol of carbon monoxide.
In conclusion, 88.1 moles of water must be produced by 88.1 moles of H₂
The reaction can also be written as an equilbrium
H₂(g) + CO₂(g) ⇄ H₂O(g) + CO(g) Kc
This statement is TRUE.
The ionization energy presents the amount of energy required for the release of the valence electron, the electron farthest from the core. The smaller the amount of energy needed for the release is, the lower the ionization energy is.
Therefore, the atoms with low ionization require little energy to release their valence electrons and they do it easier that the atoms with high ionization energy.
Answer:
Formula and structure: Lead sulfide chemical formula is PbS and its molar mass is 239.26 g mol-1. Lead sulfide is formed by the cation Pb+2 (the lesser oxidized ion of Pb) and the anion S-2 (the lesser oxidizer ion of S).
