Explanation:
Water is a polar solvent as the hydrogen and oxygen atom has large difference in their electronegativities.
Oxygen atom is highly electronegative as compared to hydrogen atom therefore, it pulls the electrons of hydrogen atom closer towards itself.
As a result, two poles will create forming a partial positive charge on the hydrogen atom and partial negative charge on the oxygen atom.
Thus, we can conclude that high electronegativity difference between oxygen and hydrogen is the cause of polarity in water molecules.
Answer:
Explanation:
one is True, an electro magnet is only magnetic because of current producing the magnetic field.
Answer:
d Rubidium
Explanation:
The atomic radius of an atom is the distance from the center of the nucleus to its outermost electron.
The atomic radius of elements varies in the periodic table, it increases as you go down in a group and decreases along the period from left to right.
All the elements listed: Hydrogen, Sodium, Lithium and Rubidium belong to the same group in the periodic table (group 1), Since atomic radius increases from top to bottom in a group, Rubidium has the largest atomic radius.
Answer:
6.460 gm is the correct answer .
Explanation:
Given
Kate’s blood volume=
blood glucose=
As we know that
The 
includes the blood glucose of the 
So 
of the Kate’s blood volume can be determined by
To convert into the gm we have divided by the 1000
Therefore the glucose in her blood=
