Answer: It’s producing 75% of it’s potential.

Example: If I were to be playing basketbal, and my body was working at 75%, then there is 25% of energy that I’m not using, making me worse than if I was using 100%.

What is the main factor that prevents the growth of tropical plants in northern part of the United States ?
slamgirl [31]

The main factor that prevents the growth of tropical plants in the northern part of the United States is the climate. The tropical plants require specific conditions to grow and flourish, including warm climate throughout the year, higher precipitation, lots of sunlight. This conditions are lacking in the northern part of the United States where we have smaller amount of sunlight, mostly cloudy sky, and the winters are extremely cold and with lots of snow, and this will contribute to the dying of a tropical plant.

A when sulfuric acid is added to sirie, hydrager
irga5000 [103]

Sulfuric acid is prepared industrially by means of the response of water with sulfur trioxide which in turn is made by way of a chemical combination of sulfur dioxide and oxygen both by way of the touch system or the chamber system.

                         H2SO4 (l) H2O (g) + SO3 (g).

The reaction is highly exothermic as an enormous amount of heat is liberated.

The usual approach is to dilute the sulfur trioxide in sulphuric acid. This produces oleum. SO3 (g) + H2SO4 → H2S2O7 (1) Oleum can be in addition diluted in water to acquire concentrated sulphuric acid.

An acid catalyst is added to protonate the carbonyl carbon. How does this catalyze the response, robust acid catalysts catalyze the hydrolysis and transesterification of esters which enables the mechanism with a view to boom the electrophilicity of the carbonyl carbon to assist protonate the carbonyl oxygen.
