Answer:
The more the precipitation which comes from the water, the more rain the clouds make witch effects vegetation and animals
Explanation:
Answer:
It becomes a positive ion and its radius decreases
Explanation:
As per the Octet rule, Barium has 2 electrons in its outermost shell. When it loses the two electron it gains two positive charge i.e Ba2+. As the barium loses the two electron from its outermost shell, the outermost shell becomes vacant and thus is no more considered as a part of atomic geometry of the barium atom and since the outermost shell is considered negligible the radius of barium atom reduces automatically.
, and the chemical formula of the compound is
Answer:
a) oxidation number of chromium is +3
b) formula of the compound is Cr2(SO4)3
Explanation:
From the name of the compound, we can see that the oxidation state of chromium is +3
We know the sulphate ion to to be SO4^2-
According to the rules of writing the formula of compounds from valencies, the valency of chromium is 3 while that is the sulphate ion is 2.
The both species can now exchange valency
Cr2(SO4)3------- This is the correct formula of the compound
Answer:
The oxidation state is +3.
chemical formula of compound is Cr₂(SO₄)₃.
Explanation:
Calculation of oxidation state:
Cr₂(SO₄)₃
Cr= ?
The oxidation state of SO₄ = -2
2x + 3( -2) = 0
2x - 6 = 0
2x = 6
x = 6/2
x= 3
The oxidation state of Cr is +3.
The Cr has valency of 3 so three SO₄ will require while the valency of SO₄ is 2 so two Cr will require.
Cr×2 and SO₄×3
Cr₂(SO₄)₃
we know that oxidation state of Cr is +3 so (3×2) = 6
and the oxidation state of SO₄ is -2 so (-2× 3) = -6
6-6= 0
The overall charge is 0, the compound will be neutral.
In multicellular organisms, the body is a system of multiple interacting subsystems. These subsystems are groups of cells that work together to form tissues and organs that are specialized for particular body functions.
Hope This Helps! Have A Nice Day!
The human body is a system of interacting subsystems composed of specialized cells and tissues, each performing a specific function. These subsystems, such as the circulatory and digestive systems, cooperate to maintain overall health and homeostasis.
The body is a system of interacting subsystems composed of a group of specialized cells and tissues. This is because each subsystem or organ system consists of particular types of cells and tissues that carry out specific functions. For instance, the circulatory system, made up of the heart, blood vessels, and blood cells, transports nutrients and oxygen throughout the body. The digestive system, including the stomach, small and large intestines, and other components, breaks down food and absorbs nutrients. These subsystems interact with each other to maintain the body's overall homeostasis and good health.

Explanation:
A precipitate is an insoluble solid that does not dissolve in a chemical reaction or or mixture.
For example,
Therefore, the precipitate formed can be separated out by filtration method.
As this method will most suitably extract the precipitate and separate it from the remaining solution.
2. Blood sugar will increase because glucagon increases blood sugar when it falls too low.
