MgSO₄(aq) + BaCl₂(aq) → MgCl₂(aq) + BaSO₄(s)
Mg²⁺ + SO₄²⁻ + Ba²⁺ + 2Cl⁻ → Mg²⁺ + 2Cl⁻ + BaSO₄
SO₄²⁻ + Ba²⁺ → BaSO₄ (the net ionic equation)
DNA and rna are both nucleus acids
Answer:
33.30 grams of CaCl2 will be required
Explanation:
Given,
Volume of solution, V= 250 ml
Molarity of solution, M= 1.20 mol/L
Molecular mass of CaCL2, S= 40+(35.5 X 2)= 111
We know,
Required mass, W= SVM/1000
Now,
W = (111 X 250 X 1.20)/1000
= 33300/1000
= 33.30
Therefore, 33.30 grams of Calcium Chloride will be required.
