The correct answer from the choices is: D
Resonance is an event where an external force or vibration moves another system to oscillate with higher amplitude at certain frequences or there is a transfer of energy between two or more different storage modes.
Answer:
Variation within genes leads to different genotypes , which can be seen by the individuals having different phenotypes . For example, the dogs above all have different fur colours and fur lengths. Genetic and environmental variation combine together to produce these different phenotypes.
Answer:
B.) No, because the coefficients could be reduced to 2,1, and 3.
Explanation:
The equation is not in its lowest molar ratio form. In this case, all of the coefficients can be divided by 2 and still result in whole numbers.
As such, the correct balanced equation is:
2 NH₃ ----> N₂ + 3 H₂
N2 is a diatomic molecule as it is composed of 2 atoms of the same element, covalently bonded to each other in this case Nitrogen.
