If the temperature of a fish population increases then, the population of fish will increase because the fish like warmer areas to breed and lay eggs.
I'm not sure if this is correct. But always use IF THEN and BECAUSE when writing a hypothesis
Answer:
Pb(NO3)2 – Lead(II) nitrate sourceaà
Other names: Lead nitrate source Plumbous nitrate source Lead dinitrate source
Appearance: White colourless crystals asource:White or colourless crystals source.
H2O – Water, oxidane source
Other names: Water (H2O) source: Hydrogen hydroxide (HH or HOH) source: Hydrogen oxide source
Appearance: White crystalline solid, almost colorless liquid with a hint of blue, colorless gas source.
Answer:
Option (D)
Explanation:
Weathering is usually defined as the disintegration of rocks at the surface of the earth. This break down of rocks is mainly caused by the geological processes that occur on the earth's surface. This process results in the formation of sediments that are transported and deposited in a new environment.
This weathering process primarily takes place in three different ways such as-
- Physical weathering- Here, the rocks are broken down by the physical agents such as wind, water, ice.
- Chemical weathering- Here the rocks are broken down when interacts with the chemical containing water.
- Biological weathering- here, the rocks are broken down due to the activities done by organisms such as plants and animals.
In the given condition, Quincy can see a real example of rock weathering in the high mountainous region, as in the mountainous region the rocks are frequently weathered and eroded by the agents such as wind, water, and ice.
Thus, the correct answer is option (D).
Answer:
a). Coordination no. of ![[Ni(en)_2(NH_3)_2]^2+](https://tex.z-dn.net/?f=%5BNi%28en%29_2%28NH_3%29_2%5D%5E2%2B)
= 6
b). Coordination no. of ![[Fe(en)(ox)Cl_2]^2-](https://tex.z-dn.net/?f=%5BFe%28en%29%28ox%29Cl_2%5D%5E2-)
= 6
Explanation:
Coordination number is defined as number of donar atoms bonded to the central atom of the complex ion.
a). Coordination no. of = 6
en or ethylenediamine is a bidentate ligand.
In bidentate ligand, two atoms directly bonded to the central atom.
NH3 is a unidentate ligand.
So, coordination no.= No. of bidentate ligand x 2 + No. of unidentate ligand
= 
b). Coordination no. of = 6
Ethylenediamine (en) is a bidentate ligand.
oxalate ion (ox) is also a bidentate ligand.
Cl is a unidentate ligand
So, coordination no.= No. of bidentate ligand x 2 + No. of unidentate ligand
=
