A team of researchers is investigating a new carbon-rich molecule important to life. They find evidence for the presence of a carbon-carbon double bond in the molecule. This observation means that the new molecule likely exists as _.

Cis and trans isomers

Explanation:

Existence of double bond in carbon rich compound confirms the presence of geometrical isomer in the compound. The compound showing geometrical isomer exists as cis and trans isomers.

Substituents or functional group around double bond decides that the compound will be cis or trans.

If functional group or bigger substituents are present on the same side of the double bond, the compound will be cis.

If functional group or bigger substituents are present on the opposite of the double bond, the compound will be trans.

answer

fusion: the energy source of stars. the energy released from the collapse of the gas into a protostar causes the center of the protostar to become extremely hot. when the core is hot enough, nuclear fusion commences. fusion is the process where two hydrogen atoms combine to form a helium atom, releasing energy.

hope it

it is to be noted that an alpha particle is an helium nucleus. so it contains 2 protons 2 neutrons and has a mass number of 4. when alpha decay particles are ejected from the nucleus it gets transformed into an atom which has atomic number less than 2 and a mass number less than 4.

an equation that could represent alpha decay is radium 226 decay of alpha particle forms radon 222.
