REPORT: Critical Analysis of the Environmental Impact of Chemical Processes
Identify a ‘human-made' chemical process (or series of processes) that has undergone changes in recent times to reduce its environmental impact. Critically examine and comment on the appropriateness of the changes. Suggest other alternatives and why they may not have been adopted.
Can you give some ideas how to start the report. or share some link regarding this question?
A certain minimum energy(E min) is required to eject an electron from a photosensitive surface. Any energy obsorbed beyond this minimum gives kinetic energy to the ejected electron.
What would be the product if D2O were added to a Grignard reagent such as phenylmagnesium bromide? Is this type of product in Grignard

A hydrogen atom initially in the n=11 quantum state emits a photon having a wavelength of 2.87144E-6 m. What is the quantum number of the final state of the atom
If the propane and air streams enter the chamber at 25.0°C and 1.20 atm (absolute), and the products leave the chamber at 290.0°C and 2.90 atm (absolute), what is the volumetric flow rate of product gas from the chamber
The diameter of a neutral helium atom is about 168 pm. Suppose we could line up helium atoms side by side in contact with one anohter. Approximately how many atoms would it take to make the distance 1 cm from end to end.
Experiments have shown that the average frequency of chirping by a snowy tree cricket depends on temperature as shown below.
A flask containing 36.8 mL of 0.138 M sodium acetate (NaC2H3O2) is titrated with 24.9 mL of 0.128 M HNO3. Calculate the pH of the solution. pKa for acetic acid = 4.757.
Ethanethiol (C2H6S) is a compound with a disagreeable odor that can be used to impart an odor to natural gas. When ethanethiol is burned, the sulfur reacts with oxygen to form SO2
