Molar mass of NaOH = 23 + 16 + 1 = 40.0 g/mol

Molar mass of HCl = 1 + 35.5 = 36.5 g/mol

NaOH + HCl = NaCl + H2O

1*40 g NaOH ------> 1*36.5 g HCl
        g NaOH -------> 7.3 g HCl

36.5 g  = 40 * 7.3

36.5 g = 292

mass ( NaOH ) = 292 / 36.5

mass ( NaOH ) = 8.0 g of NaOH

hope this helps!.

What is the general trend in electro negativity as you move from left to right across the periodic table
viva [34]

Answer:

On the periodic table, electronegativity generally increases as you move from left to right across a period and decreases as you go down a group. As a result, the most electronegative elements are found on the top right of the periodic table, while the least electronegative elements are found on the bottom left.

Which of these best explains what happens when ice melts to form liquid water?
iVinArrow [24]
Since the question says “these” I assume it was multiple choice...but anyways, intermolecular forces between some of the water molecules are breaking apart. The H2O is going from a tightly packed solid of a fixed volume to a liquid with molecules moving faster and less bonds, which can take the shape of its container. It requires energy to break a bond, so this is an endothermic process.
