Answer #1

Answer: (c) possible origin of life by combination of chemicals under suitable environmental conditions

The concept of chemical evolution is based on possible origin of life by combination of chemicals under suitable environmental conditions. The distribution of elements in the cosmos is the result of many processes in the history of the Universe. It provides us with a powerful tool to study the Big Bang, the density of baryonic matter, nucleo-synthesis and the formation and evolution of stars and galaxies.

Chemical Reactions Types and Their Equations Making Heat with Chemical Reactions Have you ever wondered how an instant heat pack works? A disposable heat pack works by a chemical reaction that combines iron in the package with oxygen from the air when the outer packaging is removed producing iron oxide. You have probably seen the product of this reaction in what is commonly called rust. The reaction releases heat, which allows the pack to reach a sufficient temperature that is...

I have provided the information for the lab below. I want to see the chemical reactions that take place during each step of the experiment. So in the procedures when a chemical was added i would like to see what the products and byproducts that were formed. I also want to see one over all reaction for this experiment to just get an overview of what exactly is happening during the experiment. Thank you:) Part B: Synthesis of [Co(NH3)5Cl]Cl2 Objective:...

Part I. Indicate whether true or false (T or F). ____ Storm water detention ponds typically are designed to regulate the outflow peak rate at or below a single target value, such as the pre-development (pre-land use change) peak runoff rate for a specified return period event. Detention storage alters the peak but not the volume of the outflow hydrograph. _____ Typical rating curves for weirs are concave upward. Typical rating curves for orifices are concave downward. ____ A sediment...

Please summarize the below article in approximately 100 words: Monumental function in British Neolithic burial practices Ian Kinnes The high-risk rate of survival for the non-megalithic series of Neolithic funerary monuments, recently re-emphasized by Piggott (1973: 34), introduces a further variable into the deductive study of burial practices. In Britain and Europe the overall distribution of monumental forms present both lacunae and a marked preponderance of cairns over earthen mounds which are in ill accord with the known or predicted...
