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).

Once the following equation is balanced with the smallest set of whole number coefficients, what is the sum of the coefficients?
katrin [286]

Answer:

9

Explanation:

To balance the equation, we need to supply the number of missing coefficients.

There are 2 moles of aluminium on the right hand side, so automatically we need to multiply the number of moles of aluminium by 2 on the left hand side.

There are 3 sulphate ions on the right hand side so we need to multiply the number on the left by 3.

And lastly since we have 6 hydrogen molecules on the left hand side now, we need to multiply the hydrogen on the right hand side by 3 to give 6

The set of coefficients = 2 3 1 3

Adding all thus yields 9
