It is totally not batholith, It is written in the section that it is Extrusive.
hydrogen, phosphorus, oxygen, calcium, nitrogen, sulfur
carbon, hydrogen, phosphorus, oxygen, nitrogen, sulfur
hydrogen, oxygen, potassium, calcium, nitrogen, sodium
Answer:
The correct option is C
Oxygen
Carbon
Hydrogen
Nitrogen
Sulfur
Phosphorus
Explanation:
Oxygen is considered to be the most abundant element to be found in the living cells. Usually, a living cell is made up of 65% oxygen.
Carbon is the element which forms the basis for life for all organisms which can be seen on the planet Earth.
Hydrogen combines with oxygen to form water which makes up 65 percent of the human body.
Nitrogen is an active constituent of molecules such as proteins which are of utter importance to an organism.
Phosphorus is present in the form of phospholipid layer which is an active constituent of the cell membranes.
Answer:
The correct option is C
Explanation:
Answer:
3.16g
Explanation:
Data obtained from the question include:
I = 4A
t = 40mins = 40 x 60 = 2400secs
Q =?
Q = It
Q = 4 x 2400
Q = 9600C
Now let us generate a balanced half equation to determine the number faraday needed to deposit metallic Cu. This is illustrated:
Cu^2+ + 2e —> Cu
From the equation,
2 faraday is needed to deposit metallic cu
1 faraday = 96500C
Therefore 2 faraday = 2 x 96500 = 193000C
Molar Mass of Cu = 63.5g/mol
193000C deposited 63.5g of Cu
Therefore, 9600C will deposit = (9600 x 63.5)/193000 = 3.16g of Cu
Answer:
Explanation:
The atomic radius of a chemical element is a measure of the size of its atoms, usually the mean or typical distance from the center of the nucleus to the boundary of the surrounding shells of electrons. Since the boundary is not a well-defined physical entity, there are various non-equivalent definitions of atomic radius. Three widely used definitions of atomic radius are: Van der Waals radius, ionic radius, and covalent radius.
