Explanation

Starch and cellulose are two very similar polymers. In fact,

they are both made from the same monomer, glucose, and have the same glucose-based repeat units.

Explanation

The electron transport chain (ETC) is critical to cellular respiration.

It culminates in: The generation of the majority of ATP molecules, which are synthesized during oxidative phosphorylation

Explanation

the elements that are positioned above the hydrogen have negative reduction potential, whereas elements that are arranged below the hydrogen have positive electrode potential.

In the electrochemical series, metals above hydrogen are good reducing agents, and those below hydrogen are good oxidizing agents. 

Explanation

Molecules held together by van der Waals forces form molecular solids.

Weak attractive forces are called Vander Waal's Forces and can be broken with little energy.

This type of attractive force occurs in the case of non-polar molecules such as H2, O2, Cl2, CH4, CO2, etc.

Explanation

The ligand diethylene triamine is tridentate

 It has 3 donor N atoms.

Explanation

Yeast is an anaerobic bacteria that is used as a leavening agent in baking bread and bakery products.

Yeast converts sugar present inside the dough into carbon dioxide and ethanol.

The carbon dioxide forms bubbles which make the dough rise and the resulting bread is soft and fluffy.

Explanation

Ethane dehydrogenation (EDH) is endothermic, and the thermodynamic equilibrium limits its conversion.

reason:

Because the EDH reaction is endothermic,

the reaction is favored at high temperatures for obtaining high ethane conversion, high activity, and high ethylene selectivity

Explanation

For a reaction 2A+B→ product, rate law is − dt/ d[A]  =k[A]]

Explanation

If the unit of rate constant is s−1, the reaction is of first order.

Explanation

In isopropyl chloride, the chlorine is attached to a carbon that is only attached to two other carbon hence it is a secondary halide.

Whereas in isobutyl chloride, the chlorine is attached to a carbon that is only attached to one other carbon hence it is primary alkyl halide.
