Answer:-
The hydrogen atoms have partial positive charges
Explanation:-
In a water molecule there are twp atoms hydrogen and oxygen.
Oxygen has more electronegativity than hydrogen. So the electrons in the bond between Oxygen and hydrogen are more towards oxygen. So hydrogen has a partial positive charge.
The Cl- has negative charge. Positive charge is attracted by negative charge.
Due to this hydrogen atoms in a water molecule are attracted to Cl- ions in sodium chloride (NaCl).
Answer:Noble gases:
are highly reactive.
react only with other gases.
do not appear in the periodic table.
are not very reactive with other elements.

It is either concave lens or mirror but since this is reflecting out rather than reflecting back it has to be concave lens. hope that helps! :’)
3.00097 x 
atoms are contained in 100.0 g of mercury.
<h3>What is moles?</h3>
The mole is defined as the amount of substance that contains as many elementary entities as there are atoms in exactly 12 g of carbon-12.”
Number of moles of mercury = 
Number of moles of mercury = 
= 0.4985 moles
Number of moles of mercury = Number of atoms = moles of Hg x 
= 0.4985 x
= 3.00097 x atoms.
Hence, 3.00097 x atoms are contained in 100.0 g of mercury.

The answer is 0.18
Because the equation for finding the molarity of a solution is:
Moles divided by Liter of solution,
so, you dissolve 0.32 mol of KCL in 1759 ml of Water 1759 ml is 1.759 liters when you plug the numbers in you get 0.18
Hope this helps,
