Answer:
The coordination number.
Explanation:
The coordination number is defined as the number of atoms surrounding an atom in a crystal lattice and indicates how tightly the atoms are packed together.
Coordination number is also known as ligancy in chemistry and it basically refers to the total or overall number of neighboring ions, atoms or molecules with respect to a central atom in a crystal lattice. The term coordination number was first defined by the notable and amiable Swiss chemist by the name, Alfred Werner in 1893.
Generally, the coordination number of an atom in a crystal lattice can have a minimum value of two (2) and a maximum value of sixteen (16). It is usually determined by the size of the ligands, central atom and the charge associated with the electronic configuration of an ion. For example, the coordination number of carbon in methane (CH4) is four (4) because an atom of carbon has four (4) atoms of hydrogen bonded to it.
Answer:
Explanation:
Both metal and wooden bowls are at the same temperature . But wood is non-conductor of heat whereas metal is conductor of heat .
If we touch the wooden bowl , heat flows from hot to cold object . Since the finger is at higher temperature , heat flows from finger to wooden bowl . But , since wood is non conducting , it does not allow heat to be conducted through it . Hence very less heat will be conducted from our finger .
On the other hand , if we touch a metal bowl , heat flows from finger to the metal bowl , without any hinderance . Hence rate of heat flow will be fast in case of metal bowl . As a result of it , we feel cool in touching metal bowl . This feeling will be absent in case of wooden bowl.
Answer:
C
Explanation:
when the equation is balanced, 2 moles of sodium is to 1 mole of hydrogen in the mole ratio so we need to find how many moles of sodium will produce hydrogen then we cross multiply
Answer: “ They add organic matter contributing to soil health increasing both the water-holding capacity and cation exchange capacity. They stimulate microbial activity and improve soil structure. Organic fertilizers also are valuable sources of micronutrients to plants. “ (the person above is correct)
