Types Of Chemical Reactions Quiz

Explanation
The given reaction involves the combination of two reactants, N2 and 3H2, to form a single product, 2NH3. This type of reaction is known as a synthesis reaction. In a synthesis reaction, two or more substances combine to form a more complex substance. In this case, nitrogen gas (N2) and hydrogen gas (H2) react to form ammonia (NH3).

Explanation
All of the options listed (mass spectrometry, Thermormogravimetric analysis, and Gravitational analysis ) are examples of analysis reactions. Analysis reactions involve the measurement and determination of the composition, structure, and properties of substances. In Mass spectrometry, a technique is used to identify and quantify the chemical composition of a sample. The thermogravimetric analysis measures the change in weight of a sample as a function of temperature, providing information about its thermal stability and decomposition. The gravimetric analysis involves the measurement of mass to determine the quantity of a substance in a sample.

Explanation
In this reaction, sodium iodide (NaI) reacts with fluorine (F2) to form sodium fluoride (NaF) and iodine (I2). This is a single replacement reaction because one element (fluorine) replaces another element (iodine) in the compound.

Explanation
The given reaction involves the exchange of ions between two compounds, resulting in the formation of two new compounds. This type of reaction is known as a double replacement reaction. In this specific case, silver chloride (AgCl) and barium bromide (BaBr2) react to form silver bromide (AgBr) and barium chloride (BaCl2). The cations (Ag+ and Ba2+) switch places with the anions (Cl- and Br-), resulting in the formation of the new compounds.

Explanation
The given chemical equation represents a combustion reaction. In a combustion reaction, a substance reacts with oxygen to produce heat and light. In this case, the reactant C2H6 (ethane) combines with 5 molecules of O2 (oxygen) to form 3 molecules of H2O (water) and 2 molecules of CO2 (carbon dioxide). This reaction is characteristic of combustion reactions as it involves the rapid oxidation of a hydrocarbon fuel in the presence of oxygen, resulting in the production of water and carbon dioxide.

Explanation
 The given reaction represents a decomposition reaction. . In this reaction, two molecules of water (H2O) break down into two molecules of hydrogen gas (H2) and one molecule of oxygen gas (O2). Decomposition reactions involve the breakdown of a single compound into two or more simpler substances.

Explanation
In the given chemical equation, 2H2O represents two molecules of water. Each water molecule contains two atoms of hydrogen and one atom of oxygen. Therefore, on the reactant side, there are two atoms of oxygen present.

Explanation
In the chemical equation you provided, 2H2O —> 2H2 + O2, there are 4 atoms of hydrogen on the left side. This is because the coefficient 2 in front of H2O indicates that there are 2 molecules of water, and each molecule of water (H2O) contains 2 atoms of oxygen. So, 2 molecules of water would contain 2*2 = 4 atoms of hydrogen.

Explanation
In the given chemical equation, N2 + 3H2 -> 2NH3, there are two nitrogen atoms on the right side. This is because the coefficient in front of NH3 is 2, indicating that there are two molecules of NH3 formed. Each molecule of NH3 contains one nitrogen atom, so there are a total of two nitrogen atoms on the right side of the equation.

Explanation
In the balanced chemical equation, N2 + 3H2 -> 2NH3, it is clear that there are three molecules of H2 (hydrogen gas) on the reactant side. Each H2 molecule contains two hydrogen atoms. Therefore, the total number of hydrogen atoms on the reactant side is 3 x 2 = 6. Since the number of atoms remains the same in a chemical reaction, there will also be six hydrogen atoms on the product side.
