The polarity of a bond between two elements can be best determined by.
kompoz [17]

The polarity of a bond between two elements can be best determined by difference in the values of electronegativity.

<h3>Determination of polarity of bond</h3>

The polarity of a covalent bond can be determined by determining the difference in electronegativity between the two bonded atoms. Electronegativity is defined as the tendency of an atom to attract electrons to itself.

So we can conclude that the polarity of a bond between two elements can be best determined by difference in the values of electronegativity.

Characteristics of pea plants are determined by genes inherited from both the parents.

Option 4.

<h3><u>Explanation:</u></h3>

Gregor Johann Mendel is also called as the father of Genetics. Mendel experimented on the pea plants to determine what happens when different types of pea plants are crossed between themselves and what actually determines the characteristics of the pea plants. After two types of experiments, he came to a conclusion that there are certain substances which he named as '' factors'' which are actually inherited from the parents. He also told that there are certain type of factors which are dominant over the others which he termed as recessive factors. So, the characteristics of the progenies depend on both the factors inherited from both the parents.

What reaction is depicted by the given equation: au3 3e− au
mrs_skeptik [129]
This is a reduction half-reaction. Initially, gold exists as Au^{3+}, and after the reaction, it has been converted to elemental gold. To make this possible, three electrons must be added to <span>Au^{3+}. This fits within the definition of reduction reactions, where the reactant gains electrons in the reaction.</span>
