<u>Answer:</u>
The temperature of the water is 70°C
<u>Explanation:</u>
Partial pressure of helium gas = 526 mmHg
Total pressure inside the jar= 760 mmHg
Suppose partial pressure of helium gas is 
and partial pressure of water is
And total pressure is 
As we know
Hence
Putting the values
In bar,
= 0.312 bar
Now according to the steam table
With the vapour pressure of water as 0.312 bar the temperature corresponds to 70°C
Explanation:
The absolute value of the difference in electronegativity (ΔEN) of two bonded atoms provides a rough measure of the polarity to be expected in the bond and, thus, the bond type. When the difference is very small or zero, the bond is covalent and nonpolar. When it is large, the bond is polar covalent or ionic.
Electrons in a polar covalent bond are shifted toward the more electronegative atom; thus, the more electronegative atom is the one with the partial negative charge. The greater the difference in electronegativity, the more polarized the electron distribution and the larger the partial charges of the atoms.
That is true. the nuclei change in nuclear rxns. Chemical rnxs use electrons..
