A table/graph of element abundances in the universe show maxima at A=80 & 90, 130 & 138, and 196 & 208. Explain these unusual double peaks. Ive already asked this same question on chegg and I still dont understand the question. please help, thank you!

Expert Solution

This review shows a brief explanation about the double peak saying that are caused by the neutron capture r process or by the neutron capture in s process.

I hope this helps, if you need more details below you can find the source.

Show clearly, with calculation steps, how to make 200ml of 90% and 80%(v/v) ethanol, respectively. Show clearly, with calculation steps, how to make 70% (v/v) ethanol + 1% (v/v) acetic acid (final volume = 200ml).

Experiments show that each element in the periodic table has a unique set of spectral lines. What is the best explanation for this observation? Each atom has a unique nucleus. The number of electrons within each atom is unique. Each element has a unique set of interactions between its electrons and its protons. The motion of the electrons within each atom is unique. Each atom has a unique set of energy levels.

What is a water footprint? You can show it on a graph or table. What food-consumption patterns or direct water-use habits explain your water footprint? Note: Your income is used to estimate your water footprint from the use of industrial goods. This is not a very exact estimate. Choose a couple of water-intensive foods that you consume and indicate in which countries or regions they are produced. Are these countries or regions water-stressed? Do you think your diet is relevant...
