Answer: Option (4) is the correct answer.

Explanation:

According to the reactivity series, a more reactive metal has the ability to replace a less reactive metal in a chemical reaction.

It is known that calcium is more reactive than magnesium. So, in a chemical reaction magnesium can never replace calcium.

For example, Mg(s) + Ca(OH)_2(aq) \rightarrow Ca(s) + Mg(OH)_2(aq)

Therefore, this given reaction is not possible. But rest all given reactions are possible.

Thus, we can conclude that out of the given options Mg(s) + Ca(OH)_2(aq) \rightarrow Ca(s) + Mg(OH)_2(aq) reaction will not occur as written.

synthetic Plastics are made by linking many simple carbon molecules together to form much larger molecules. the process is calle
Nutka1998 [239]

Answer:

Polymerization

Explanation:

Several natural and man-made organic compounds are enormous molecules which contains hundreds of thousands of atoms per molecule.

The giant molecules formed are produced through the process of polymerization.

Polymerization is the linking of monomers through chemical reactions to form long chain polymer molecules.

Monomers are small molecules that are joined to form polymers.

Synthetic plastics are derieved from synthetic polymers. These synthetic materials are very useful and vital due to their great size. Their size premits a certain complexity of structure which makes the molecules disposed in a regular pattern with respect to one another. They stretch out nearly to alongside of one another or coil up independently. The polymerization of monomers to form plastics fosters the various uses these giant molecules are put to.

Nitrogen dioxide reacts with carbon monoxide to produce nitrogen monoxide and carbon dioxide. NO2(g) + CO(g) ⟶ NO(g) + CO2(g) A
Naya [18.7K]

<u>Answer:</u> The rate law for the reaction is \text{Rate}=k[NO_3][CO]

<u>Explanation:</u>

Rate law is defined as the expression which expresses the rate of the reaction in terms of molar concentration of the reactants with each term raised to the power their stoichiometric coefficient of that reactant in the balanced chemical equation.

In a mechanism of the reaction, the slow step in the mechanism determines the rate of the reaction.

For the given chemical reaction:

NO_2(g)+CO(g)\rightarrow NO(g)+CO_2(g)

The intermediate reaction of the mechanism follows:

Step 1:  2NO_2(g)\rightleftharpoons NO_3(g)+NO(g);\text{ (fast)}

Step 2:  NO_3(g)+CO(g)\rightarrow NO_2(g)+CO_2(g);\text{(slow)}

As, step 2 is the slow step. It is the rate determining step

Rate law for the reaction follows:

\text{Rate}=k[NO_3][CO]

Hence, the rate law for the reaction is written above.

Elenna [48]

Answer:

In this fragile environment, genetically engineered fish would compete with their wild counterparts for food and space, and could even potentially interbreed with them. They will also bring new diseases and cause changes to basic food webs and ecosystem processes that are difficult to anticipate.
