Hydrogenation is a process that involves adding hydrogen to the double bonds in unsaturated fatty acids to extend the shelf-life of food products.
<h3>What is
hydrogenation?</h3>
Hydrogenation can be defined as a chemical process that involves an addition of hydrogen to the double bonds in unsaturated fatty acids to extend the shelf-life of food products.
<h3>The purpose of
hydrogenation.</h3>
In Science, some of the purpose of hydrogenation include the following:
- Conversion of liquid oil into solid fat.
- To alter a fat's consistency level.
- To stabilize a fat or an oil.

Answer:
691.7 mmHg is the resulting pressure
Explanation:
Tha Gay-Lussac's law states that the pressure of a gas is directly proportional to its absolute temperature under constant volume. The equation is:
P1T2 = P2T1
<em>Where P is pressure and T asbolute temperature of 1, initial state and 2, final state of the gas.</em>
<em />
Computing the values of the problem:
T1 = 273 + 25 = 298K
P1 = 755.0mmHg
T2 = 273 + 0 = 273K
P2 = ?
755.0mmHg*273K = P2*298K
<h3>691.7 mmHg is the resulting pressure</h3>
Iron becomes rusted especially in damp air but never in a dry air, this is one of the many unique characteristics of iron. Iron is also ductile and malleable. It is found in the seventh group of the periodic table. It has four different and unique crystalline forms and completely dissolves in dilute acids. The two chemical compounds that can be found or made from iron are the bivalent iron also known as ferrous and the trivalent iron or known as ferric compounds.
Answer:
The number of electrons in a neutral atom is equal to the number of protons. The mass number of the atom (M) is equal to the sum of the number of protons and neutrons in the nucleus. The number of neutrons is equal to the difference between the mass number of the atom (M) and the atomic number (Z).
Explanation:
