Answer :

The complete net ionic equation is :

2OH^-(aq)+2H^+(aq)\rightarrow 2H_2O(l)

Explanation :

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

Net ionic equation : 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 balanced molecular equation will be,

Ca(OH)_2(aq)+2HNO_3(aq)\rightarrow Ca(NO_3)_2(aq)+2H_2O(l)

The complete ionic equation in separated aqueous solution will be,

Ca^{2+}(aq)+2OH^-(aq)+2H^+(aq)+2NO_3^{-}(aq)\rightarrow Ca^{2+}(aq)+2NO_3^{-}(aq)+2H_2O(l)

In this equation the species, Ca^{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 complete net ionic equation is:

2OH^-(aq)+2H^+(aq)\rightarrow 2H_2O(l)

How many miles are there in 20g of KClO3 (k=39 Cl=35.5 O=16)​
SashulF [63]
<h3>Answer:</h3>

0.144 moles

<h3>Explanation:</h3>
  • The relationship between mass of a compound, number of moles and molar mass of the compound is given by;
  • Number of moles = Mass ÷ Molar mass
  • Molar mass is equivalent to the relative formula mass of the compound that is calculated the atomic masses of the elements making the compound.

In this case;

Our compound, KClO3 will have a molar mass of;

= 39 + 35.5 + 4(16)

= 138.5 g/mol

Mass of KClO3 is 20 g

Therefore;

Number of moles = 20 g ÷ 138.5 g/mol

                            = 0.144 moles

Thus, the number of moles in 20 g of KClO3 is 0.144 moles

Why it is important for steel to go through a fluid phase as it is being produced
BigorU [14]
T is important to go through a fluid phase as it is being produced because the object must go through heat to be melted and then it should be put into a mold to be formed. Also, it go though heat to keep it from cracking and go to be cooled and harden.
