Answer:
Explanation:
It is possible to answer this question knowing Hess's law that says you can sum half-reactions enthalpy cahnge to obtain enthalpy change of the total reaction. Using the reactions:
<em>(1) </em>2NO(g) → N₂(g)+O₂(g) ΔH = -180,6 kJ
<em>(2) </em>N₂(g) + O₂(g) + Cl₂(g) → 2NOCl(g) ΔH = +103,4 kJ
The reverse reactions of (1) and (2) are:
<u>N₂(g)+O₂(g)</u> → 2NO(g) ΔH = +180,6 kJ
2NOCl(g) → <u>N₂(g) + O₂(g)</u> + Cl₂(g) ΔH = -103,4 kJ
The sum of these reactions is:
2NOCl(g) → 2NO(g) + Cl₂(g) ΔH = +180,6 kJ -103,4 kJ = <em>77,2 kJ</em>

- Unsaturated fats include double bonds that provide structures that prevent development of tightly bonded compounds.
- The characteristics of the phospholipid head and tails determine how the phospholipids are arranged in the bilayer cell membrane.
This is why even though Olive oil and butter both contain fats, olive oil is liquid at room temperature and butter is solid.
- Since saturated fat makes up the majority of butter, it is solid at room temperature.
- Olive oil is an unsaturated fat since it is liquid at room temperature.
- Through hydrogenation processes, an unsaturated fat can be converted to a saturated fat.
<h3>What are saturated fats?</h3>
- a form of fat believed to be less healthy in the diet than unsaturated fat because it contains a higher percentage of fatty acid molecules lacking double bonds.
- butter, ghee, suet, lard, coconut oil and palm oil, cakes, biscuits, fatty cuts of meat are some of the examples.
<h3>What are unsaturated fats?</h3>
- a form of fat that is thought to be healthier in the diet than saturated fat because it contains a high percentage of fatty acid molecules with at least one double bond.
- Olive, peanut, and canola oils, Avocados, Nuts such as almonds, hazelnuts, and pecans, Seeds such as pumpkin and sesame seeds are some of the examples.

Answer:
e. The reaction is product favored and would be considered a voltaic (galvanic) cell
Explanation:
An electrochemical cell produces electrical energy from electrochemical reactions.
A voltaic cell is a type of electrochemical cell that produces electrical energy by spontaneous electrochemical reactions. In a voltaic cell, the cell potential is always positive unlike in an electrolytic cell.
Hence, given the fact that the cell potential is positive, it is a product favoured voltaic cell.

I think it’s b I’m not sure so sorry if incorrect. Take care.
