Answer:

The minimum amount of energy a plant must absorb to produce 15.0 g of glucose is 57.0 kilo calories.

Explanation:

Energy released on combustion of 1 g gram of glucose = -3.80 kcal

Energy released on combustion of 1 grams of glucose = -3.80 kcal

So, the energy required to form 1 gram of glucose is = 3.80 kcal

The energy absorbed by the plants to produce 15 grams of glucose be :

$15.0 g\times 3.8 kcal/g=57.0 kcal$

The minimum amount of energy a plant must absorb to produce 15.0 g of glucose is 57.0 kilo calories.

A weak bond called a ______ bond results from an attraction between a slightly positive region in a molecule and a slightly nega

Answer: The weak bond having slightly positive region and a slightly negative region is polar covalent bond.

Explanation:

Covalent bond is defined as the bond which is formed by the sharing of electrons between the atoms. For Example: HCl, $CH_4$ etc..

They are of two types:

Polar covalent bond: This bond is formed when difference in electronegativity between the atoms is present. When atoms of different elements combine, it results in the formation of polar covalent bond.

In this bond, a dipole is created. More electropnegative atom will have a slight negative charge and less electronegative atom will have a slight positive charge. For Example: $CO_2,NO_2$ etc..

Non-polar covalent bond: This bond is formed when there is no difference in electronegativity between the atoms. When atoms of the same element combine, it results in the formation of non-polar covalent bond. For Example: $N_2,O_2$ etc..
