The answer is covalent bonds.
The chemical formula for calcium hydroxide is Ca(OH)₂ and that of nitric acid is HNO₃. By these chemical formula it can be deduced that the number of equivalents per mole of Ca(OH)₂ is 2 because of 2 OH⁻ and for HNO₃ is 1 because of H⁺.
For the neutralization reaction, the number of equivalents should be equal.
V₁n₁ = V₂n₂
Substituting the known values and with the incorporation of the concept above,
(V₁)(0.0250 mol/L)(2 equivalents/mol) = (33.50 mL)(0.020 mol/L)(1 equivalent/mol)
V₁ = 13.4 mL
Hence, the volume of calcium hydroxide needed is approximately equal to 13.4 mL.
The Molecular Equation is as follow,
Ba(NO₃)₂ ₍aq₎ + MgSO₄ ₍aq₎ → BaSO₄ ₍s₎ + Mg(NO₃)₂ ₍aq₎
The Total Ionic Equation is as follow,
Ba²⁺₍aq₎ + 2NO₃⁻ ₍aq₎ +Mg²⁺ ₍aq₎ + SO₄²⁻ ₍aq₎ → Mg²⁺ ₍aq₎ + 2NO₃⁻ ₍aq₎ + BaSO₄ ₍aq₎
Here, Mg²⁺ and NO₃⁻ are spectator Ions,
So,
The Net Ionic Equation is as follow,
Ba²⁺ ₍aq₎ + SO₄²⁻ ₍aq₎ → BaSO₄ ₍aq₎
Answer:
The chemical characteristics of carbon affect the characteristics of organic molecules due to its tetravalent nature. It has four valence electrons in which it shares with other elements in order to form an octet configuration.
Carbon atoms are also capable of forming double and triple bonds with other atoms. These properties help determine the functional group present and gives us a knowledge of the chemical features such as polarity, melting and boiling present in the compound.
