Why the copper is able to replace the silver, but the reverse reaction will not result in a replacement reaction?

Chemistry
1 answer:
PSYCHO15rus [73]3 years ago
7 0

Answer:

Copper is more reactive and higher in the activity series

Explanation:

Copper is able to replace the silver in a replacement reaction because it is more reactive and higher in the activity series.

Substances or ions that are higher in the activity series are typically more reactive than those ones below them.

In like manner, they are able to replace the lowers ones in a chemical reaction due to their higher reactivity potential.

A less reactive element and a lower one in the activity series cannot displace a higher one in the series.

Imagine you are about to investigate what happens when sodium and potassium are mixed together. Before you begin your experiment
inessss [21]

Explanation:

Potassium and Sodium are both metals on the periodic table. Both elements are found on the s-block of the table. Therefore, it is not possible for both of them to combine to form a compound.

For a compound to form two elements must combine in a definite order to given  single product.

The combination is facilitated by a loss, gain or sharing of electrons between two species. This leads to an attraction between the combining species.

Both Sodium and potassium would prefer to lose electrons and there is no reason for them to combine to form a compound.

How many equivalents are in a solution that contains 0.25 moles Mg2+ and 0.50 moles Cl–?
Vinil7 [7]

Answer:

Explanation:

Mg²⁺ is divalent , hence

Molecular weight / 2 = equivalent weight .

.25 moles = 2 x .25 equivalents = .5 equivalents .

Cl⁻ is monovalent so

molecular weight = equivalent weight

.50 mole = .50 equivalent

Total equivalent = .50 of Mg²⁺ + .50 of Cl⁻

= 1 equivalent .

If 28 grams of N reacts completely with 12 grams of H2, then how many
Bogdan [553]

Answer:

Mass of NH₃ produced = 34 g

Explanation:

Given data:

Mass of nitrogen = 28 g

Mass of Hydrogen = 12 g

Mass of NH₃ produced = ?

Solution:

Chemical equation:

N₂ +  3H₂    →   2NH₃

Moles of nitrogen:

Number of moles = mass/molar mass

Number of moles = 28 g/ 28 g/mol

Number of moles = 1 mol

Moles of hydrogen:

Number of moles = mass/molar mass

Number of moles = 12 g/ 2 g/mol

Number of moles = 6 mol

Now we will compare the moles of hydrogen and nitrogen with ammonia.

                            H₂              :               NH₃

                            3                :                2

                            6                :             2/3×6 = 4 mol

                           N₂              :                NH₃

                            1                :                 2

Number of moles of ammonia produced by nitrogen are less thus it will act as limiting reactant.

Mass of ammonia produced:

Mass = number of moles × molar mass

Mass =  2 mol  ×  17 g/mol

Mass = 34 g

In the addition of hbr to 1-butyne the electrophile in the first step of the mechanism is
irga5000 [103]
Answer:
            <span>In the addition of hbr to 1-butyne the electrophile in the first step of the mechanism is <u>Hydrogen atom of HBr</u>.

Explanation:
                   In this reaction first of all HBr approaches the triple bond. A Pi Complex (weak inter-molecular interactions) is formed between the two molecules. And the triple bond attacks the partial positive hydrogen atom creating a negative charge on Bromine along with positive charge on itself (Sigma Complex). In second step the negative Bromide attacks the positive carbon of Butyne.</span>
