The answer is
decomposition
Answer:
The footprints of a dinosaur and the burrow of an ancient shrimp are examples of - Trace Fossils
Explanation:
A trace fossil or ichnofossil is defined as a geological record of biological activity. These provide us with indirect evidence of life in the past, such as the footprints, burrows, tracks, borings, etc that are left behind by animals, rather than the preserved remains of the body of the actual animal itself.
In order to create a cation, one first needs to understand that a cation is an atom with excessive positive particles (proton) as compared to negative particles (electrons). Hence, a cation is always positively charge.
From the image simulating the orbital, proton and neutron are represented by either of the red or yellow ball respectively since both particles occupy the innermost part of the atom. The electron is usually revolves in the orbitals and hence, is represented by the blue ball.
Assuming that the proton is represented by the red ball, all that is required to create a cation would be to have more red ball in the nucleus than blue balls outside the nucleus.

Answer:hydride and alkyl shift
common product of water.
Explanation:
Alcohols (ROH) can be thought of as derivatives of water in which one of the hydrogen atoms has been replaced by an alkyl group. If both of the hydrogen atoms are replaced by alkyl groups, we get an ether (ROR). These compounds are named by adding the word ether to the names of the alkyl groups.
The order of the ease of dehydration of alcohols is: tertiary > secondary > primary. Secondary and tertiary alcohols are best dehydrated by dilute sulfuric acid. By heating an alcohol with concentrated sulfuric acid at 453 K (180°C).
