What is the net ionic equation of the reaction below?
faltersainse [42]

Answer:

Net ionic equation:

 Ca⁺²(aq)  + CO²⁻₃(aq)     →   CaCO₃(s)

Explanation:

Chemical equation:

K₂CO₃  +   CaCl₂    →   KCl  +  CaCO₃

Balance chemical equation:

K₂CO₃(aq)  +   CaCl₂(aq)    →   2KCl(aq)  +  CaCO₃(s)

Ionic equation:

2K⁺(aq) + CO²⁻₃(aq)  +   Ca⁺²(aq)  + 2Cl⁻(aq)  →   2K⁺(aq) + 2Cl⁻(aq)  + CaCO₃(s)

Net ionic equation:

CO²⁻₃(aq)  +   Ca⁺²(aq)      →   CaCO₃(s)

The K⁺(aq) and Cl⁻ (aq) are spectator ions that's why these are not written in net ionic equation. The CaCO₃ can not be splitted into ions because it is present in solid form.

Spectator ions:

These ions are same in both side of chemical reaction. These ions are cancel out. Their presence can not effect the equilibrium of reaction that's why these ions are omitted in net ionic equatio n.

What type of reaction is BaCl2 + Na2SO4 → 2NaCl + BaSO4?
maria [59]

Answer:

Double Displacement reaction

Explanation:

BaCl2 + Na2SO4 → 2NaCl + BaSO4

Double displacement reaction occurs when the cations and anions of the two reacting compound interchange, forming a new products. From the equation given above, Na^+ switch place with Ba^2 + and likewise Cl^- with (SO4) ^2- to form NaCl and BaSO4.

17. The equation below represents a chemical reaction that occurs in living cells.
RSB [31]

Answer:

36 atoms

Explanation:

  • C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + energy

The reactants are in the left side of the equation. <u>First we determine how many atoms are there in the C₆H₁₂O₆ molecule</u>:

  • 6 C atoms + 12 H atoms + 6 O atoms = 24 atoms in total

There are two atoms in a O₂ molecule, and there are 6 O₂ molecules in the equation:

  • 2 * (6 O atoms) = 12 atoms in total

The total number of atoms in the reactants is

  • 24 + 12 = 36 atoms
