Explanation:

The student most likely observed both (A) Vacuole and (C) Chloroplast that led him to the conclusion, that the cell is a plan cell.

Reason :

In a plant cell, Vacuole occupies 70% to 90% of the total volume of the cell, making it easier to identify.

Chloroplast contains photosynthetic pigment called chlorophyll (green in colour), which is only found in plant cell.

What is the net ionic equation of the reaction of MgSO4 with Pb(NO3)2? Express you answer as a chemical equation including phase

Nady [450]

Answer : The net ionic equation will be,

$Pb^{2+}(aq)+SO_4^{2-}(aq)\rightarrow PbSO_4(s)$

Explanation :

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

Spectator ions : The same number of ions present on reactant and product side which do not participate in a reactions.

The given balanced ionic equation will be,

$MgSO_4(aq)+Pb(NO_3)_2(aq)\rightarrow Mg(NO_3)_2(aq)+PbSO_4(s)$

The ionic equation in separated aqueous solution will be,

$Mg^{2+}(aq)+SO_4^{2-}(aq)+Pb^{2+}(aq)+2NO^{3-}(aq)\rightarrow PbSO_4(s)+Mg^{2+}(aq)+2NO^{3-}(aq)$

In this equation, $Mg^{2+}\text{ and }NO_3^-$ are the spectator ions.

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

The net ionic equation will be,

$Pb^{2+}(aq)+SO_4^{2-}(aq)\rightarrow PbSO_4(s)$
