Answer:
b. oxygen side being slightly negative and the hydrogen side being slightly positive.
Explanation:
The water molecule is a polar molecule, that is to say that its distribution of electronic density is different throughout the molecule.
In this way, in the water molecule there is a negative partial charge towards the oxygen atom and a positive partial charge towards the hydrogen atom.
This polar characteristic of the water molecule allows ions and other molecules to exhibit water solubility and is widely used in chemical reactions.
A.) half - life of a radioactive substance is defined as the time during which concentration of the substance becomes half the initial value.
Desert plants commonly have small wax coated leaves to prevent moisture and water from evaporating. It is an important feature in desert plants to adapt to the arid climate. The wax on the leaves also protect the leaves from the chilling temperature of the desert at night.
<h2>ANSWER OF EACH PART ARE GIVEN BELOW</h2>
Explanation:
A)
We know, each mole contains 
atoms.
It is given that mass of one oxygen atom is m= 
.
Therefore, mass of one mole of oxygen, 
.
Putting value of n and 
,
B)
Given,
Mass of water in glass=0.050 kg = 50 gm.
From above part mass of one mole of oxygen atoms = 16.0 gm.
Therefore, number of mole of oxygen equivalent to 50 gm oxygen
