Explanation:

Inspite of having similar intermolecular forces, CS2 has a higher boiling point than CO2, since it has a greater molar mass. The potential energy of molecules reduces until a certain level as they get closer to each other. Although the polarity of both CO2 and CS2 are cancelled because of their linear structure.

Determine the value of x and write the complete chemical formula of the hydrate

Annette [7]

In order to determine the formula of the hydrate, [Anhydrous Solid⋅xH2O], the number of moles of water per mole of anhydrous solid (x) will be calculated by dividing the number of moles of water by the number of moles of the anhydrous solid (Equation 2.12.

Match the items with the appropriate option.

tekilochka [14]

Answer:

Breakdown of glucogen.

Glycogen phosphorylase of muscle and liver, which catalyzes the reaction

(Glucose)n + Pi ----> (glucose) n-1 + glucose 1-phosphate

Shortened glycogen chain

* acyl-CoA dehydrogenase

Dehydro genation of fatty acyl–CoA produces a double bond between the alpha and beta carbon atoms

Regulatory Enzyme of fatty acid breakdown

*Pyruvate dehydrogenase complex

Pyruvate derived from glucose and other sugars by glycolysis, is oxidized to acetyl-CoA and CO2 by the pyruvate dehydrogenase (PDH) complex, located in the mitochondria of eukaryotic cells and in the cytosol of bacteria.

Pyruvate converted to acetyl CoA

*Citrate synthase

The first reaction of the citric acid cycle is the condensation of acetyl-CoA with oxaloacetate to form citrate, catalyzed by citrate synthase:

Citric acid cycle.

* Lactate dehydrogenase

When animal tissues cannot be supplied with sufficient oxygen to support aerobic oxidation of the pyruvate and NADH produced in glycolysis, NAD+ is regenerated from NADH by the reduction of pyruvate to lactate.

Anaerobic respiration

*Phosphofructokinase

Glucose 6-phosphate can flow either into glycolysis or through any of several other pathways,

including glycogen synthesis and the pentose phosphate pathway. The metabolically irreversible reaction catalyzed by PFK-1 is the step that commits glucose to glycolysis.

Regulatory enzyme of glycolysis

*succinate dehydrogenase

Part of both the citric acid cycle and oxidative phosphorylation

*adenylate cyclase

Converts ATP to cAMP

*Glucose 6-phosphate dehydrogenase

Glucose 6-phosphate dehydrogenase catalyzes the first step in the pentose phosphate pathway, which produces NADPH.

Pentose phosphate pathway

*Glucose 6-phosphatase

Glucose 6-phosphate is dephosphorylated by glucose 6-phosphatase to yield free glucose.

Determine the number of lone pair electrons on each H in NH3. Z of N= 7, H=1 A. 0 B. 3 C. 1 D. 2

Darya [45]

Answer:

Option A. 0

Explanation:

To know the number of lone pair on each H in NH3, we shall determine how NH3 is formed. This is illustrated below:

3H + N —> NH3

Three atoms of Hydrogen, H reacted with 1 atom of nitrogen to produce ammonia, NH3. Each atoms contribute one electron each to form the covalent bond in NH3.

Hydrogen has only one electron and it will share it with the nitrogen atom to produce ammonia.

Further details can be seen in the attached photo.

Further more, in the attached photo, we can see that there is no lone pair of electron in the hydrogen atom as all it's electron has been used to form bond with the nitrogen atom. Only the nitrogen has a lone pair of electron.

Therefore, there are zero lone pair of electron on each hydrogen, H atom in ammonia, NH3.

What makes a pure substance different from a heterogeneous mixture?

Vaselesa [24]

Answer: The components of a pure substance are single elements or compounds instead of a mixture of compounds.

Explanation: Pure substance consits of a pure type of particle.

All elements and compounds that are considered as pure will have fixed boiling point and melting point.
