Aspirin(3) was synthesized by esterification reaction of salicylic acid(1) with acetic anhydride(2) catalyzed by aluminum dihydrogen tripolyphosphate/loaded sulfur diatomite. The effects of materials ratio[r = n(2) ∶ n(1) ],reaction time,temperature and catalyst amount on the yield of 3were investigated by the single-factor experiments. The results showed that the four main factors influencing the yield of 3 are in the following order: r reaction time reaction temperature catalyst amount. Under the optimum reaction conditions[1 was 50 mmol,the catalyst amount was 5%,r was3. 14,at 81 ℃ for 40 min],the yield was 88. 6%. The yield still reach 83. 3% after reuse for five times of the catalyst

How does energy from the Sun drive the cycling of matter?

Schach [20]

Answer:

solar energy drives the cycle by evaporating water from the oceans, lakes, rivers, and soil. As liquid water evaporates or transpires, it forms water vapor and clouds, where water droplets eventually gain enough mass to fall back to Earth as precipitation.

Which method reduces carbon dioxide emissions by storing carbon dioxide for a long time?

Rudiy27

B. carbon sequestration

Explanation:

Carbon sequestration is a method that reduces carbon dioxide emissions by storing them for a long time.

It is long term harvesting or sequestering of carbon dioxide from the atmosphere in order to avert air pollution and climatic change problems.
Carbon sequestration is usually employed in the storage and capture of atmospheric carbon dioxide.
The carbon dioxide can be sequestered using biologic or geologic means.
Carbon dioxide gas is used to enhance oil recovery from geologic formations that have low permeability or those with low formation pressure to push out the oil.

Atoms of different chemical elements can be differentiated based on the number of.

Alona [7]

The atoms of different chemical elements can be differentiated based on the number of protons.

Each chemical element is differentiated by his number of protons. This number of protons is also knowing as atomic number and it is represented by the letter (Z).

The atomic number represented the number of protons in the nucleus of an element. For example:

The element that has only 1 proton in his nucleus is Hydrogen atom.
The element that has 2 protons in his nucleus is Helium atom.

The atom is the smallest part of the composition of matter, it is indivisible and is composed of a nucleus that has protons and neutrons, and around the nucleus there are the electrons.
