We know that 1 mole of sodium contains Avogadro number of atoms. - But we have to find the number of atoms in 0.2 mole of sodium. - Therefore 0.2 moles of sodium (Na) contains 12.046×1023atoms in it.

Which is the Net Ionic Equation for:
arlik [135]

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

Explanation:

Complete ionic equation : In complete ionic equation, all the substance that are strong electrolyte and are present in an aqueous state and represented in the form of ions.

Net ionic equation : In the net ionic equations, we do not 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 complete balanced ionic equation will be:

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

 In this equation, Cl^- 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:

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

25. a. If 2.50 mol of copper and 5.50 mol of silver nitrate are available to react by single replacement, identify the limiting
Paraphin [41]

The limiting reagent is Copper (Cu)

First, balance the reaction before determining the limiting reactant.

Cu + 2Ag

Cu(NO3)2 + 2Ag from NO3

Take the beginning material amount and calculate the number of moles of one of the products to identify the limiting reactant. The limiting reactant is the one that produces a product with the fewest moles.

5.50×1.00/2.00=2.75

The limiting reactant is the one that is consumed first and sets a limit on the quantity of product(s) that can be produced. Calculate how many moles of each reactant are present and contrast this ratio with the mole ratio of the reactants in the balanced chemical equation to get the limiting reactant.

Copper is the limiting reactant since there are only 2.50 mol of it and only 2.50 mol of AgNO3 will result from the reaction.
