Answer:

POCl3

Explanation:

A compound is a substance made up of atoms of different elements. The number of atoms each element posseses make up the chemical formula of the compound. In this question, a certain compound is made up of three chlorine atoms (Cl3), one phosphorus atom (P), and one oxygen atom (O).

Combining these atoms of different quantity together, this means that the compound will have a chemical formula: POCl3. This compound is called phosphorus oxychloride.

1 Srcl (aq) + 1 H,60,(aq) → 2 HCl(aq) + 1 Srso (s)
Mrac [35]

Answer:

Mass = 245.72 g

Explanation:

Given data:

Mass of SrCl₂ react = ?

Mass of H₂SO₄ = 300.0 g

Solution:

SrCl₂  +  2H₂SO₄     →     2HCl + Sr(HSO₄)₂

Number of moles of H₂SO₄:

Number of moles = mass/molar mass

Number of moles =  300.0 g/ 98.079 g/mol

Number of moles = 3.1 mol

Now we will compare the moles of SrCl₂ and  H₂SO₄.

                   H₂SO₄         :       SrCl₂

                        2             :           1

                      3.1             :         1/2×3.1 = 1.55 mol

Mass of SrCl₂:

Mass = number of moles × molar mass

Mass = 1.55 mol × 158.53 g/mol

Mass = 245.72 g
