Answer:
The answer is (3) HClO. In the Cl2, chlorine has an oxidation number of zero. In HCl, the oxidation number is -1. In HClO2, the oxidation number is +3.
Explanation:
Answer:
Plastic ma be a homogeneous mixture
Explanation:
as the homogeneous mixture are the equal ration blended solution so plastic are also blended in equal proportion with the help of molten state
Answer:
The atoms are ranked in decreasing order as follows:
Fluorine ---4
Carbon ----3
Boron ------2
Beryllium --1
Explanation:
Effective nuclear charge (Zeff) is defined as the difference between the actual nuclear charge (the atomic number, Z) and the shielding constant (S).
It is calculated by finding the atomic number and electronic configuration, attributing a shielding value to each electron, adding all the shielding values and using the formula:
Z eff = Z - S
Effective nuclear charges:
An atom of carbon: 3.25
An atom of fluorine: 5.20
An atom of beryllium: 1.95
An atom of boron: 2.60
Answer:
If damage is done to the human skeletal structure it cannot be healed or reversed: INCORRECT.
Explanation:
- Human DNA is capable of repairing itself: <em>CORRECT.</em> It has several ways to do it, repairing bases through excision, by photoreactivation, repairing mismatches, by repairing double-strand breaks and activating SOS responses.
- If damage is done to the human skeletal structure it cannot be healed or reversed:<em> INCORRECT.</em> The human body has a bone healing process that allows the creation of a cartilaginous scaffold than then becomes a bone matrix transforming the outer laminar bone into compact bone.
- The human skin is capable of self-heal due to the human cells: <em>CORRECT. </em> A wound in human skin is healed in a process that includes hemostasis, the creation of a blood clot, followed by an inflammatory phase and de successive creation of new epidermis. Many human cells are involucrated, such as fibroblasts and macrophages.
- When synthetic material gets damaged it's irreversible: <em>CORRECT. </em>These kinds of materials do not have a system to self-heal by itself.
- Biological material has the capability of healing due to vascularity and its cells: <em>CORRECT.</em> Vascularization is the growth of blood vessels, it is fundamental to have effective transport of oxygen, nutrients, and removal of cell-secreted waste for the survival of cells, this allows the biological material to heal.
