Answer:
See below
Step-by-step explanation:
An exothermic reaction tends to occur spontaneously because the products are more stable than the reactants.
Nature tries to get to the lowest energy state.
The physical properties used by scientists to describe all matter, sight, smell, taste, color, texture, mass, weight, volume, and density.
Answer:
Change in enthalpy for the reaction is -536 kJ
Explanation:
- Overall chemical reaction can be represented a summation of two given elementary steps with slight modification.
- Take reaction (1a) and divide stoichiometric coefficients by 2
- Take reverse reaction (2a) and divide stoichiometric coefficient by 2
- Then add these two modified elementary steps to get overall chemical reaction
is an additive property. hence value of will be changed in accordance with modification

Answer:
Deposition
Explanation:
Deposition: The gaseous substance turns directly into a solid without undergoing the liquid phase
Answer:
The molecular structure affects solubility mainly biased on its polarity or bonded ions.
Explanation:
Polar molecules will better interact with the water molecules and will dissolve easier. Nonpolar molecules can dissolve if they are small enough, however they don't interact well with the polar molecules. Bonded ions, such as NaCl split into a cation Na and an anion Cl which the positive charge on the Na will be attracted to the oxygen, and the negatively charged Cl will be attracted to the positive Hydrogen.
**Remember this rule, like dissolves like, meaning nonpolar dissolves nonpolar and polar dissolves polar.
I hope this helps!
