Answer:
D
Explanation:
Stereoisomers are molecules that have the same molecular formula but different 3-d arrangement of atoms. Three types exist but we are focusing on geometrical cis-trans isomerism here. In a single bond, the molecules can rotate around fixed points and there is no fixed 3-d geometry. In butene and other double-bond-containing molecules (the double bond is signified through the "-ene" suffix and the "-2-" indicates that the double bond begins on the second carbon in the chain), rotational motion is stopped by the double bond. This causes two different types of molecules to occur in nature: cis-2-butene, in which the carbon atom in the chain is on the same side at both ends of the double bond, and trans-2-butene, in which the carbon atom is on opposite sides (like a beach chair if the seat was a double bond). So the stereoisomer of trans-2-butene is cis-2-butene, which is Option D.
Hello,
The fuel used for nuclear power is Uranium.
So uranium is used for nuclear power.

A mole is a very important unit of measurement that chemists use. A mole of something means you have 602,214,076,000,000,000,000,000 of that thing, like how having a dozen eggs means you have twelve eggs. Chemists have to measure using moles for very small things like atoms, molecules, or other particles.
<h3>What is mole and atoms?</h3>
The number of atoms or other particles in a mole is the same for all substances. The mole is related to the mass of an element in the following way: one mole of carbon-12 atoms has 6.02214076 × 1023 atoms and a mass of 12 grams.
<h3>Why is the mole unit so important?</h3>
It represents the link between the microscopic and the macroscopic, especially in terms of mass. A mole of a substance has the same mass in grams as one unit (atom or molecules) has in atomic mass units.
