Answer:

B.The use of piers and beams to build a strong foundation for a house

Explanation:

Foundation engineering falls under geotechnical engineering which uses both soil and rock mechanics to design the foundation structure of any building so as to avoid overloading of the soil. Foundation engineering is important to ensure stability and prevent lateral movement of the building.

Cancer research is done by cell biologist. Medical professionals help to cure sick people. Chemists study galvanic corrosion.

What is the highest occupied molecular orbital in the O2 molecule?

Aleonysh [2.5K]

H2 is known to exist. For dihydrogen, H2, we can identify the frontier molecular orbitals (FMOs). The highest occupied molecular orbital (or HOMO) is the σ (sigma) 1s MO. The lowest unoccupied MO (LUMO) is the σ* (sigma star) 1s MO which is antibonding.

Answer:

10.5 kl

Explanation:

$1.05*10^7ml\\=\frac{1.05*10^7}{10^3}l\ [1 ml= 1/1000 l]\\=1.05*10^4\\=10500 l\\=\frac{10500}{1000} l\ [1l=1/1000kl]\\=10.5 kl$

Draw the structure of the organic product(s) of the grignard reaction between phosgene (clcocl) and excess phenylmagnesium bromi

Jobisdone [24]

Phosgene on reacting with <span>phenylmagnesium bromide generates benzoyl chloride.

Since, </span>phenylmagnesium bromide is added in excess. It would further react with benzoyl chloride to form benzophenone.

Benzophenone on further reacting with phenylmagnesium bromide, and aqueous treatment, gives triphenylmethanol.

Entire reaction pathways is shown below:
