6. Which of the following is a binary compound?<br> a. CaCO3<br> b. CuSO4<br> c. H2O<br> d. Pb(NO3)2
slamgirl [31]

Answer:

<em>The answer to your question is </em><em>c. H2O</em>

Explanation:

<em>a. CaCO3 ----> Calcium Carbonate is obviously not a binary compound because it contains more than two elements. </em>

<em>b. CuSO4 ----> CuSO4 stands for copper(II) sulfate. Sulfate is the polyatomic ion SO4 -2.</em>

<em>c. H2O ----> Binary molecular compounds are composed of only two elements. Examples are H2O, NO, SF6 etc. </em>

<em>d. Pb(NO3)2 ----> Lead(II) nitrate is an inorganic compound with the chemical formula Pb(NO3)2.</em>

<em>I hope this helps and have a great day!</em>

What is the formula of hexaaquamanganese(ii) sulfate? express your answer as a chemical formula?
Digiron [165]

Answer : The formula of hexaaquamanganese(II)sulfate is [Mn(H_2O)_6]SO_4.

Explanation :

Rules for writing formulas of coordination complexes :

  • Central metal is written first and then the ligands are written along with their prefixes.
  • The anion ligands are written before the neutral ligands.
  • If there are more than one anion ligands or neutral ligands then they are written in alphabetical order.

The given name of complex is, hexaaquamanganese(ii) sulfate.

In this, the central metal is manganese which is written as Mn and the ligand is water (which is a neutral ligand) is written as H_2O and an anion is sulfate which is written as SO_4.

Water is a neutral ligand and sulphate has a charge of -2. As the overall complex is neutral the metal bears a +2 charge which is represented in Roman numeral after the metal.

Therefore, the formula of hexaaquamanganese(II)sulfate is written as [Mn(H_2O)_6]SO_4.

35g of HF was prepared by reacting 112g of CaF2 with an excess of H2SO4 calculate the percentage yield
Tom [10]

Answer: 61%


The reaction equation should be

CaF2 + H2SO4 → 2HF + CaSO4

For every 1 molecule CaF2 used, there will be 2 molecules of HF formed. The molecular mass of CaF2 is 78/mol while the molecular mass of HF is 20g/mol. If the yield is 100%, the amount of HF formed by 112g CaF2 would be: 112g/(78g/mol) * 2 * (20g/mol)=57.43g

The percentage yield of the reaction would be: 35g/57.43g= 60.94%
