Might be false
Hope so
So sorry if it is wrong
Answer:
If I remember correctly it should be B because it went from Cu^2 to Cu^0
Explanation:
A volumetric flask is used to contain a predetermined volume of substance and only measures that volume, for example 250 ml.
Conical flasks can be used to measure the volume of substances but the accuracy they provide is usually up to 10ml. Conical flasks are used in titrations, reactions where the liquid may boil, and reactions which involve stirring.
Pippettes are of two types, volumetric and graduated. Pippettes are used where high accuracy is required and volumetric pippettes come in as little as 1 ml. Pippettes are usually used in titrations.
Graduated cylinders come in a wide variety of sizes and their accuracy can be down to as much as 1 ml. They are used to contain liquids.
All three molecular nitrogen, carbon monoxide, and cyanide ion are isoelectronic but CO and CN⁻ are toxic as compared to N₂ because N₂ has very high bond energy due to the presence of triple bonds making it stable in comparison to others.
<h3>What is Isoelectronic species?</h3>
The phrase "isoelectronic species," which means "same electric" or "equal charge," describes two atoms, ions, or molecules with the same electronic structure and the same amount of valence electrons. Chemical species that are isoelectronic often have identical chemical characteristics. It is referred to as having the same isoelectronic or being isoelectronic to other atoms or ions with the same electronic configurations.
