For two compounds to be isomers, they must be composed of exactly the same atoms (that is to say, equal numbers of each element in their formula) but the atoms are arranged differently.
No. There are two molecular requirements that must be met to indicate aromaticity. In order to be aromatic a molecule must: 1) have a ring of pi electrons above and below the molecule. This means: a. The molecule must be cyclic. b. All atoms in the ring must be sp2 hybridized c. The molecule must be planar. 2) have an odd number of pairs of pi electrons. Since acetic acid is not cyclic, it cannot meet the first requirement and therefore cannot be aromatic. There are, however, delocalized electrons that increase the stability of the compound.
UV-vis active molecules must have easily deformed electron clouds. This requirement is met for molecules with lots of pi-bonds that are directly connected together, or conjugated.
For a substance or solution to exhibit electrolyte behavior, it must be composed of ions that can move freely in the solution and the substance must be able to conduct electricity when dissolved in a solvent.
For a molecule to absorb infrared radiation, it must have a change in its dipole moment when it vibrates. This means that the molecule must have different charges distributed unevenly within it, causing it to interact with the infrared radiation and absorb its energy.
Rainbows can be caused by many forms of airborne water. These include not only rain, but also mist, spray, and airborne dew. That's the first requirement ... the weather conditions: Liquid water droplets in the air. But that doesn't guarantee a rainbow. Here's what else you need: -- The sun, shining in a clear sky, standing less than 42 degrees above the horizon, behind you. If more than 42 degrees high, none of a rainbow can be above the horizon. -- From where your head is, the clear sun and the watery air must be in exactly opposite directions.
A condition that must be met is a requirement.
Age requirements for Utah governor is 30 years
helium does not from any compounds.
A requirement to be met that is not clearly defined. "You're done cleaning when I'm satisfied."
No, everyone met the age limit requirement.
Requirement in medical policy met
The requirements vary from state to state in the US. Some have Continuing Education Requirements that must be met every year. Others have no such requirement.
In Georgia the minimum age is 6 years old, unless a medical waiver is obtained. The minimum height is 4'9" and weight 40 pounds which must also be met with age requirement.
To establish an electric current, there are two requirements that must be met. There must be a closed conducting path that goes from the positive terminal to the negative terminal. The second requirement is to have an electric circuit for the energy to move a positive test charge against the electric field.
