Answer:There are three main properties of chemical bonds that must be considered—namely, their strength, length, and polarity. The polarity of a bond is the distribution of electrical charge over the atoms joined by the bond. Specifically, it is found that, while bonds between identical atoms (as in H2) are electrically uniform in the sense that both hydrogen atoms are electrically neutral, bonds between atoms of different elements are electrically inequivalent. In hydrogen chloride, for example, the hydrogen atom is slightly positively charged whereas the chlorine atom is slightly negatively charged. The slight electrical charges on dissimilar atoms are called partial charges, and the presence of partial charges signifies the occurrence of a polar bond.
Explanation:
So,
Formate has a resonating double bond.
In molecular orbital theory, the resonating electrons are actually delocalized and are shared between the two oxygens. So the carbon-oxygen bonds can be described as 1.5-bonds (option B). I'm not sure if option C is correct, however, because the likelihood of both delocalized electrons being in the area of one oxygen atom is less than 50%.<span />
Both figures are mixtures,
Figure II is a heterogenous mixture
Figure I is a homogenous mixture

The scale used to measure the basicity of a substance is called the pH Scale. A base which when measured on a pH scale obtains a value greater than 7 but less than or equal to 10 is weak base and from 10-14 is strong base
<h3>Meaning of Base and basicity</h3>
A base is any substance that has the ability to accept hydrogen ion in water and also netralize an acid when mixed together.
Basicity is an attribute associated with the pH scale measurement of values above 7 to 14.
Basicity increases on the scale from 7 to 14. On the pH scale 7 is neutral. So the higher we go the more basic a solution becomes until it gets to its highest point which is 14.
In conclusion, The scale used to measure the basicity of a substance is called the pH Scale. A base which when measured on a pH scale obtains a value greater than 7 but less than or equal to 10 is weak base and from 10-14 is strong base
