When the following two solutions are mixed:
k2co3(aq)+fe(no3)3(aq)
the mixture contains the ions listed below. sort these species into spectator ions and ions that react.
drag the appropriate items to their respective bins.
no3-)aq), fe3+ , co3 2-, k+
part b
what is the correct net ionic equation, including all coefficients, charges, and phases, for the following set of reactants? assume that the contribution of protons from h2so4 is near 100 %.
ba(oh)2(aq)+h2so4(aq)?

For Part A: The spectator ions are and the ions that react are

For Part B: The net ionic equation is given below.

Explanation:

Net ionic equation of any reaction does not include any spectator ions.

Spectator ions are defined as the ions which does not get involved in a chemical equation. They are found on both the sides of the chemical reaction when it is present in ionic form.

The chemical equation for the reaction of iron (III) nitrate and potassium carbonate is given as:

Ionic form of the above equation follows:

As, potassium and nitrate ions are present on both the sides of the reaction. Thus, it will not be present in the net ionic equation and are spectator ions.

The net ionic equation for the above reaction follows:

Hence, the spectator ions are and the ions that react are

The chemical equation for the reaction of sulfuric acid and barium hydroxide is given as:

Ionic form of the above equation follows:

All the ions are present in this reaction. Thus, no ion is considered as spectator ions.

b is the correct

in the given question, the partial pressure is calculated by using the ideal gas equation, that is, pv = nrt

here, p is pressure, v is volume = 25 l, n is number of moles = 0.0104 moles, r is gas constant = -0.0821 l.atm / mol.k

t is temperature = 273 k

p = nrt / v

p = (0.0104 mol × 0.0821 l.atm / mol.k × 273 k) / 25 l

= 0.0093 atm
