Answer:inner Diameter =9.19cm
Explanation:
Density is calculated as Mass/ Volume
therefore
Volume= Mass/ Density = 1360g/ 0.953g/ml=1,427 ml
1ml = 1cm³
1,427ml = 1,427cm³
Also We know that Volume of a cylinder = πr²h or πr²l
1,427cm³ = 3.142 x r² x 21.5 cm
r² = 1,427cm³/ (3.142 x 21.5cm)
r² =21.124cm²
= r²
r= 4.596cm
Diameter= 2 x radius
=2 x 4.596
=9.19cm
The charged species carrying the positive and the negative charges are called ions. The ionic compounds formed will be NaCl, Na₂SO₄, MgCl₂, and MgSO₄.
<h3>What are ionic compounds?</h3>
Ionic compounds are the substances formed by the interaction and the bond formation between the ions of the opposite charges. A cation of the ion loses an electron to the anion.
The crisscross method is used to determine the ionic compounds from the respective ions. In Na⁺ and Cl⁻, both have charge of one that got canceled to form NaCl.
In Na⁺ and SO₄²⁻, the charges of the ions are crossed to form Na₂SO₄. With ions Mg²⁺ and Cl⁻ the +2 charge of magnesium crosses with chloride ion to form, MgCl₂. Similarly, Mg²⁺ and SO₄²⁻ cross their charges to form MgSO₄.
Therefore, the ionic compounds formed are NaCl, Na₂SO₄, MgCl₂, and MgSO₄.
