Answer:
Option (A).
Explanation:
A). Structural formula
Structural formula of a chemical compound represents a graphic structure of a molecule.
B). Chemical formula
Chemical formula shows the chemical proportions of the atoms which constitute a molecule of the compound.
C). Space filling model
Space filling model is a 3-D molecular model in which atoms are represented by the spheres whose radii are proportional to the radii of the atoms and distances between the atoms are proportional to the distances between the atomic nuclei.
D). A ball and stick model
This model shows the 3-D positions of the atoms and the bonds between them.
In this model atoms are represented by the spheres and bonds connected by the sticks.
Therefore, model shown is STRUCTURAL FORMULA.
Option (A) is the answer.
Answer:
Starch.
Explanation:
When the triiodide combine with starch, it forms dark blue colour. Amylose in starch is responsible for the occurrence of a deep blue color when the iodine is combine with the starch. The iodine molecule goes inside of the amylose coil which makes a linear triiodide ion complex that goes into the coil of the starch that leads to an intense blue-black color in the end so we can say that starch turns the colour into blue.
Answer:
The 3d and 4s orbitals are completely filled, and the 4p orbital is partially filled.
Explanation:
B it helps then analyze their experience
<span>Hydrogen atoms accompany electrons as they are transferred in biological systems in order to ensure that the metabolism proceeds to completion.
This is considered the main purpose of the electron shuttles.
