Answer:
Silicon does not form double bonds with oxygen, whereas carbon is capable of forming double bonds with oxygen. While the carbon dioxide molecular structure is linear, the silicon dioxide has an extended, different covalent structure.
Explanation:
If the sizes of the atoms of Silicon (Si) and Carbon (C) are compared to each other, the Si atoms are larger than carbon - which implies that the Si-O bonds will be longer than the C-O bonds. As a result, the p orbitals present on the Si and O atoms aren't very near to each other, in order to get together for the required overlap sideways which could have formed a stable pi bond. Hence, Silicon forms only single covalent bonds with Oxygen in silicon dioxide, in the form of a diamond structure with each Si atom being connected to its four neighbouring atoms through an O atom.
On the other hand, in the case of carbon dioxide, C is perfectly capable of forming double bonds with O. The different p orbitals are brought close together, resulting in a sideways overlap that leads to two pi bonds, twisted at a right angle to each other. As a result, the Carbon in carbon dioxide bonds with 2 oxygen atoms but not 4.
Answer:
The seperation of chromosomes won't be possible.
Explanation:
The metaphase and anaphase are stages in cell division other stages are interphase, prophase, and telophase.
The metaphase stages has to do with the alignment of chromosomes in what is known as mitosis while the anaphase stage deals with the sister chromatids seperation. After the seperation the sister chromatids move towards the opposite poles.
From what we have in the question, the cells won't be able to divide because the chromosomes that would turn to chromatids which in turn goes into the daughter cells won't be able to undergo the seperation.
