Answer:
option c
Explanation:
Solution is formed when a solute is dissolved a solvent.
Formation of solution is decided by the interaction between solute and solvent.
When a solute is dissolved, the intermolecular interactions in between solute molecules are broken. And New interactions are formed between solute and solvent.
In order to form solution, the solute-solvent interactions must be stronger than solute-solute and solvent-solvent in interactions.
Therefore, among given the option c is correct.
Answer:
d
Explanation:
Aluminium and Indian are in the same group/family
Sodium and Sulfer are in the same period
Elements of the same family have similar properties
Since sulfur and sodium aren't in the same family they dont share properties
Answer:
Scientists believe that convection circulation within the mantle helps continents to move. As heat from Earth's innermost layer—the core—transfers to the bottom layer of mantle rock, the rock warms, softens, and rises upward. ... This churning motion in the mantle appears to be a major factor in plate movement.
Explanation:
Answer:
In the third step of the citric acid cycle, the oxidation of isocitrate takes place and one molecule of carbon dioxide is released.
Explanation:
In the first step of citric acid cycle, acetylCoA combines with a four-carbon molecule, oxaloacetate, forming a six-carbon molecule, citrate.
In the second step, the citrate in the presence of enzyme anicotase is converted into isocitrate.
<u>In the third step, the oxidation of isocitrate takes place and one molecule of carbon dioxide is released leaving behind one five-carbon molecule called as α-ketoglutarate. During this step, NAD⁺ is reduced to form NADH. </u>
<u>This is first round of the citric acid cycle that could possibly release a carbon atom originating from this acetyl CoA.</u>
On series of reaction, another carbon dioxide molecule also being relased and oxaloacetate is regenerated again.
