The answer is atomic number.
Explanation: Meendelev believed in putting it in order by atomic mass but that didn’t make since so another scientist by the name of Henry Moseley arranged the elements by atomic number which made the periodic table make more since. Because they were in order of which properties they had.

What mass of calcium chloride is produced from 5.59 mol of hydrochloric acid
svp [43]

From the mole ratio of the reaction as given in the equation of the reaction, the mass of calcium chloride that can be produced from 5.59 mol of hydrochloric acid is 310.245 g.

<h3>What mass of calcium chloride can be produced from 5.59 mol of hydrochloric acid?</h3>

The mass of calcium chloride that can be produced from 5.59 mol of hydrochloric acid is determined from the equation of the reaction.

The equation of the reaction is given below:

Ca²⁺ (aq) + 2 HCl (aq) ---> CaCl₂ (s) + H₂ (g)

From the equation of the reaction, the mole ratio of HCL and calcium chloride is 2 : 1

Therefore, moles of calcium chloride that can be produced will be:

The moles of calcium chloride = 5.59 moles * 1/2

The moles of calcium chloride = 2.795 moles

The mass of calcium chloride produced = moles * molar mass

Molar mass of calcium chloride = 111 g/mol

Mass of calcium chloride produced = 2.795 * 111

Mass of calcium chloride produced = 310.245 g
