11. How did the solubility product constant Ksp of KHT in pure water compare to its solubility product constant Ksp of KHT in KC

Airida [17]

Answer:

Explanation:

KHT is a salt which ionises in water as follows

KHT ⇄ K⁺ + HT⁻

Solubility product Kw= [ K⁺ ] [ HT⁻ ]

product of concentration of K⁺ and HT⁻ in water

In KCl solution , the solubility product of KHT will be decreased .

In KCl solution , there is already presence of K⁺ ion in the solution . So

in the equation

[ K⁺ ] [ HT⁻ ] = constant

when K⁺ increases [ HT⁻ ] decreases . Hence less of KHT dissociates due to which its solubility decreases . It is called common ion effect . It is so because here the presence of common ion that is K⁺ in both salt to be dissolved and in solvent , results in decrease of solubility of the salt .

Determine if the phrases below are true for catabolic pathways only, anabolic pathways only,or can apply to both pathways, by so

Ivan

Answer:

Catabolic pathways;

Pathway produces more ATP than it consumes

Supplies NADH for oxidative phosphorylation

Anabolic pathways only:

Consumes more ATP than it produces

Can require reducing agent

Both pathways;

At least one enzyme is regulated

All reactions are catabolized by enzymes

One or more reactions are endergonic without ATP

Explanation:

Catabolic pathways;

Complete oxidation of glucose and then produces more ATP. Oxidative phosphorylation is an example of catabolic pathway.

From the given following conversions are considered as catabolic pathways.

Pathway produces more ATP than it consumes

Supplies NADH for oxidative phosphorylation

Anabolic pathways:

Anabolic pathways produces new molecules and it requires energy in the form of ATP for the formation of new bonds.

From the given following conversions are considered as anabolic pathways.

Consumes more ATP than it produces

Can require reducing agent.

Both pathways;

Metabolic pathways are occuring in the cell only few enzymes are regulate these pathways.

At least one enzyme is regulated

All reactions are catabolized by enzymes

One or more reactions are endergonic without ATP

Which part of a star does the star’s energy come from?

Paraphin [41]

Answer:

For most of its active life, a star shines due to thermonuclear fusion of hydrogen into helium in its core, releasing energy that traverses the star's interior and then radiates into outer space. At the end of a star's lifetime, its core becomes a stellar remnant : a white dwarf , a neutron star , or, if it is sufficiently massive, a black hole .
