Answer the following Question Down Below...
bonufazy [111]

The mass number of the atom is 21, the atomic number is 9, and the element is Fluorine. There are 9 protons, 9 electrons, 12 neutrons, and the elemental symbol is F.

<h3>Properties of an atom</h3>

For every atom:

  • Protons and neutrons are located in the nucleus and the addition of both equals the mass number of atoms.
  • Electrons are located outside the nucleus, in orbitals.
  • Neutral atoms have the same number of electrons and protons

In the diagram:

Number of electrons = 9

Number of protons = 9

Number of neutrons = 12

Mass number = 12 + 9

                      = 21

Atomic number = number of protons

                         = 9

Element with atomic number 9 = Fluorine

Symbol of the element = F

How many milliliters of a 1.25 molar hydrochloric acid (HCl) solution would be needed to react completely with 60.0 grams of cal
stich3 [128]

<u>Answer:</u>

2400 mL

<u>Explanation:</u>

Ca + 2HCl \implies CaCl_2 + H_2

According to this equation, the stoichiometric ratio between Ca and HCl for the complete reaction is 1:2.

We know that the number of moles of Ca can be calculated using the mole formula. (<em>number of moles = mass / molar mass</em>)

Moles of Calcium = \frac{60}{40} = 1.5 mol

So the moles of HCl = 1.5 \times 2 = 3.0 mol

<em>Volume of HCl solution = Moles of HCl/ concentration of HCl</em>

Volume of HCl solution = \frac{3}{1.25} = 2400 mL
