Barium Cynanide is the compound
A white rabbit would therefore have (ff)
If a trait is recessive, then it can only be expressed if both alleles (individual letters) are recessive (lowercase).
Answer:
B. Nonpolar covalent bond
Explanation:
Between two Nitrogen atoms, a non-polar covalent bond would be formed.
So, what is the nature of a covalent bond, and what makes a covalent bond non-polar?
A covalent bond is a type of bond that forms between two atoms that shares their valence electrons. The valence electrons are donated by the two atoms and they are shared in order to achieve an octet. This bond type is predominantly between atoms that have an electronegativity difference less than 0.5. Using the electronegativity values, we see that a difference of 0 would be obtained.
Due to equal affinities of the two atoms for the valence electrons, none of them will pull the electrons closer to themselves. There won't be any form of charge separation on the two atoms and a Nitrogen molecule will form. This makes the bond type a non-polar covalent type.
Answer:
You find a separatory funnel set up in a fume hood. There are clearly two visible layers. Describe a method you could use to determine which layer is the aqueous layer.
Explanation:
In the separating funnel, the liquid with less density exists at the top layer and the liquid with greater density will exist at the bottom layer.
To identify the aqueous layer, add a bit of water to the separating funnel.
Then, observe where the water will go and mix.
If it mixes with the bottom layer, then the bottom layer is the aqueous layer.
If water mixes with the top layer, then top layer is the aqueous layer.
Answer:
I'd say ALL OF THE ABOVE.
A Mechanical wave is a disturbance that transfers energy as it moves through a medium without displacement of the medium itself.
It can Either be Transversal or Longitudinal.
It is Transversal when the particles of the medium move perpendicular to the wave motion.
It requires a medium and begin at a source with a disturbance
So
ALL THE OPTIONS SEEM LEGIT.
