Answer:

c. fluorine

Explanation:

A single replacement reaction is defined as the chemical reaction in which a strong molecule replaces the weak molecule from a compound.

In a single replacement reaction, the chloride ion in NaCl can be replaced by fluorine and gives Sodium fluoride as fluorine (F) is stronger than chlorine (Cl) and from other given molecules also. So the single replacement reaction between NaCl and F will be:

NaCl + F2 => NaF + Cl2

Hence, the correct answer is "c. fluorine".

Complete and balance the molecular equation for the reaction of aqueous copper(II) chloride, CuCl2, and aqueous potassium phosph

aleksandrvk [35]

<u>Answer:</u> The net ionic equation is written below.

<u>Explanation:</u>

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

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

The chemical equation for the reaction of copper (II) chloride and potassium phosphate is given as:

$3CuCl_2(aq.)+2K_3PO_4(aq.)\rightarrow Cu_3(PO_4)_2(s)+6KCl(aq.)$

Ionic form of the above equation follows:

$3Cu^{2+}(aq.)+6Cl^-(aq.)+6K^+(aq.)+2PO_4^{3-}(aq.)\rightarrow Cu_3(PO_4)_2(s)+6K^+(aq.)+6Cl^-(aq.)$

As, potassium and chloride ions are present on both the sides of the reaction, thus, they will not be present in the net ionic equation.

The net ionic equation for the above reaction follows:

$3Cu^{2+}(aq.)+2PO_4^{3-}(aq.)\rightarrow Cu_3(PO_4)_2(s)$

Hence, the net ionic equation is given above.

2A1 + 3Cl2 → 2AICI:<br> a) How many moles of AICIz form when 3.2 mol of Cl2 reacts?

crimeas [40]

Answer:

<u>2.13</u> moles of AlCl3 are produced from 3.2 moles of Cl2

Explanation:

Moles : The amount of substance that contain as many particles as present in 12 grams of C-12.

The balanced equation for the reaction is :

$2Al +3Cl_{2}\rightarrow 2AlCl_{3}$

This reaction shows the following :

2 mole Al = 3 mole Cl2 = 2 mole AlCl3

In question we are asked to calculate the moles of AlCl3 produced from Cl2

So, we will use only Cl2 andAlCl3 moles

3 mole Cl2 = 2 mole AlCl3

1 moles of Cl2 will give =

$\frac{2}{3}$ of AlCl3

3.2 moles of Cl2 will give =

$\frac{2}{3}\times 3.2$ of AlCl3

= 2.133 moles
