So,
The Lewis structure for ethylene is two carbons double-bonded to each other, and two hydrogens single-bonded to each carbon atom.
Each bond symbolizes two shared valence electrons. Since the carbon atoms are double-bonded, they share four (4) valence electrons (the other electrons are in lower energy levels and do not appear because they typically don't react when higher energy-level electrons are on top of them).
Answer would be B. CNS the central nervous system
Answer:
The hydrogen bond between hydrogen fluoride molecules is stronger because the polarization in H-F molecule is stronger.
Explanation:
The more polarization happens in the molecule the stronger the inter-molecular hydrogen bond is.
Consider water (H - O - H) and hydrogen fluoride (H - F), the polarization of the (H - F) bond is stronger than the (O - H) bond due to the higher electronegativity of the fluoride atom. Actually, fluoride has the highest electronegativity.
Answer : The correct option is, Red
Explanation :
Prism : It is defined as the two plane surfaces inclined at an angle with respect to each other.
Or we can say that prism is a type of glass in which the while light is refracted through the prism, it splits into different colors with different wavelength and frequency. The color observed through prism are violet, indigo, blue, green, yellow, orange and red (VIBGYOR).
The increasing order of bending the light by a prism are :
Red < Orange < Yellow < Green < Blue < Indigo < violet
That means the color that is bent the least by a prism is, red color and the color that is bent the most by a prism is, violet color.
Hence, the correct option is, Red
Answer:
would be the conjugate base in this reaction according to the Bronsted-Lowry acid-and-base theory.
Explanation:
Among the reactants, the Bronsted-Lowry acid is the species that supplies protons . The Bronsted-Lowry base would be the species that accept the protons.
On the product side of the equation, the BL-acid donates a proton to produce the conjugate base. The BL-base accepts a proton to produce the conjugate acid.
In this case, each molecule donates a proton to form one ion. Hence,
Each molecule would accept a proton to produce an ion. Hence,
