What is the ionic equation for the following<br> 2FeCl(aq)<br> 3Mg(s)<br> 3MgCl(aq)<br> 2Fe(s)
amid [387]

Answer : The net ionic equation will be,

2Fe^{3+}(aq)+3Mg(s)\rightarrow 3Mg^{2+}(aq)+2Fe(s)

Explanation :

In the net ionic equations, we are not include the spectator ions in the equations.

Spectator ions : The ions present on reactant and product side which do not participate in a reactions. The same ions present on both the sides.

The given balanced ionic equation will be,

2FeCl_3(aq)+3Mg(s)\rightarrow 3MgCl_2(aq)+2Fe(s)

The ionic equation in separated aqueous solution will be,

2Fe^{3+}(aq)+6Cl^{-}(aq)+3Mg(s)\rightarrow 3Mg^{2+}(aq)+6Cl^{-}(aq)+2Fe(s)

In this equation, Cl^{-} is the spectator ion.

By removing the spectator ions from the balanced ionic equation, we get the net ionic equation.

The net ionic equation will be,

2Fe^{3+}(aq)+3Mg(s)\rightarrow 3Mg^{2+}(aq)+2Fe(s)

In a science lab, Cash mixes two clear liquids together in a beaker. Bubbles are produced, and a white solid forms and settles t
Novosadov [1.4K]

Answer:

A chemical change occurred, so even if Cash heats it, the white solid will remain.

Explanation:

  • A physical change occurred, so if Cash heats it, the white solid will dissolve to form the original mixture of clear liquids.
  • A physical change occurred, so even if Cash heats it, the white solid will remain.
  • A chemical change occurred, so if Cash heats it, the white solid will dissolve to form the original mixture of clear liquids.
  • A chemical change occurred, so even if Cash heats it, the white solid will remain.

<em>The correct answer would be that a chemical change occurred, so even if Cash heats it, the white solid will remain.</em>

Chemical changes occur when atoms in a substance or mixture of substances are rearranged, leading to the formation of new substances.

<u>In this case, the mixture of the two clear liquids led to the formation of gas in form of bubbles and a white solid forms that settle at the bottom. The formation of these 2 substances from the mixture of the two clear liquid is an indication of chemical reaction/changes. Hence, even if cash heats the resulting mixture, the white solids will likely remain.</u>
