Explanation:
Brass (a copper-zinc alloy)-The brass bond is brittle because it is a metal alloy.
Rubber-Rubber bonding is covalent.
Barium sulfide (BaS) — Bonding is primarily ionic (but some covalent) depending on the respective Ba and S positions in the periodic table.
Solid xenon-Bonding is van der Waals in solid xenon, since xenon is a noble gas.
Bronze-Bonding is metallic in that it is an alloy with silver.
Nylon-The bonding in nylon is primarily covalent with some van der Waals Forces.
Aluminum phosphide (AlP)-Aluminum phosphide (AlP) bonding is covalent in principle but it also has some ionic character.
Answer:
C) the double bond results in the bypassing of the first oxidation step of the pathway, thereby eliminating one FADH2 product
Explanation:
The beta oxidation of fatty acids is the process by which long chain saturated and unsaturated fatty acids are oxidized to the two-carbon product, acetylCoA.
The beta oxudation of fatty acids occurs in four steps after which the chain length is shortened by 2 with cleavage of an acetylCoA molecule.
The first step involves the oxidation of the fatty acid with introduction of a double bond between C-2 and C-3 of the long carbon chain. This reaction produces FADH2 which donates its electrons to electron carriers in the electron transport chain tomproduce 1.5 moles of ATP. This is the case with saturated fatty acids.
However, in unsaturated fatty acids (which are less reduced than saturated fatty acids) where there is already a double bond innthe molecule, the double bond results in the bypassing of the first oxidation step of the pathway, thereby eliminating one FADH2 product.
This causes a reduction In the number of ATP produced by unsaturated fatty acids when compared to saturated fatty acids.
Answer:
Partial pressure for each of the three gases, in the mixture is 15 atm
Explanation:
Remember that the total pressure of a mixture, is the sum of partial pressures from the gases contained in the mixture.
Our total pressure = 45 atm
The 3 gases have the same pressure, so we can propose this equation:
3x = 45 atm
where x is the partial pressure for each of the three gases.
x = 45/3 → 15 atm
