Which chemical symbols will complete the equation for this single displacement reaction?

2NaCl + Br2

This is because Na (Sodium) still needs to retain the coefficient or amount of two. Since Chlorine already has 2 on the reactants side, having a two in front would make sense so both elements can have a two.

Bromine would have the subscript of two as in the reactants side of the equation, it is also under the coefficient of two. Thus, it would need to carry it to the products side in order to keep the equation balanced.

Hope this helps!

<u>Answer:</u> The chemical equation for the given reaction is given below.

<u>Explanation:</u>

A single displacement reaction is defined as the reaction in which more reactive element displaces the less reactive element from its chemical reaction.

A+BX\rightarrow AX+B

Element A is more reactive than element B.

The chemical equation for the reaction of sodium bromide with chlorine gas follows:

2NaBr+Cl_2\rightarrow 2NaCl+Br_2

By Stoichiometry of the reaction:

2 moles of sodium bromide reacts with 1 mole of chlorine to produce 2 moles of sodium chloride and 1 mole of bromine gas.

1. Compare and contrast the characteristics of metals and nonmetals.
Alona [7]

Answer:

1.Metals

These are very hard except sodium

These are malleable and ductile  pieces

These are shiny

Electropositive in nature

Non-metals

These are soft except diamond

These are brittle and can break down into pieces

These are non-lustrous except iodine

Electronegative in nature

2. The electrochemical series helps to pick out substances that are good oxidizing agents and those which are good reducing agents.In an electrochemical series the species which are placed above hydrogen are more difficult to be reduced and their standard reduction potential values are negative.

3. Arrhenius theory, theory, introduced in 1887 by the Swedish scientist Svante Arrhenius, that acids are substances that dissociate in water to yield electrically charged atoms or molecules, called ions, one of which is a hydrogen ion (H+), and that bases ionize in water to yield hydroxide ions (OH−).

4. The common application of indicators is the detection of end points of titrations. The colour of an indicator alters when the acidity or the oxidizing strength of the solution, or the concentration of a certain chemical species, reaches a critical range of values.

The Synthesis Reaction of aluminum (Al) and iodine (I) forms a new, more complex
marysya [2.9K]

Answer:

Aluminum iodide (AlI₃)

Explanation:

The synthesis reaction of aluminum (Al) and iodine (I) can be illustrated as shown below:

Aluminium exhibit trivalent positive ion (Al³⁺)

Iodine exhibit univalent negative ion (I¯)

During reaction, there will be an exchange of ion as shown below:

Al³⁺ + I¯ —> AlI₃

Thus, we can write the balanced equation for the reaction as follow:

Al + I₂ —› AlI₃

There are 2 atoms of I on the left side and 3 atoms on the right side. It can be balance by putting 2 in front of AlI₃ and 3 in front of I₂ as shown below:

Al + 3I₂ —› 2AlI₃

There are 2 atoms of Al on the right side and 1 atom on the left side. It can be balance by putting 2 in front of Al as shown below:

2Al + 3I₂ —› 2AlI₃

Thus the equation is balanced.

The product on the reaction is aluminum iodide (AlI₃)
