which type of chemical reaction occurs when natural gas is burned?(1 point) responses exothermic exothermic endothermic endothermic replacement replacement decomposition

Answers

Answer 1

The type of chemical reaction that occurs when natural gas is burned is exothermic.

A chemical reaction is a process that leads to the formation of a new substance. During a chemical reaction, the atoms of the original substance are rearranged to create new molecules or compounds. In this process, the bonds between atoms break apart and reform, leading to the creation of new substances. Natural gas is a fossil fuel that is used to generate electricity, heat homes and buildings, and fuel vehicles. It is a hydrocarbon gas that is primarily composed of methane. It is a widely used source of energy due to its abundance, low cost, and relatively low environmental impact. An exothermic reaction is a type of chemical reaction that releases energy in the form of heat or light. During this reaction, the products of the reaction have less energy than the reactants. This energy is released into the surroundings as heat or light. The combustion of natural gas is an exothermic reaction. When natural gas is burned, it reacts with oxygen to produce carbon dioxide, water vapor, and energy. The reaction is exothermic because the energy of the products is less than the energy of the reactants, and the difference in energy is released as heat into the surroundings.

Answers

The student obtained an optically active product after exposing r-1-bromo-2-propanol to sodium hydroxide. The proton NMR of the product is also provided.

The structure of the compound that the student isolated is:CH3 – CH (OH) – CH2 – Br

In the given compound r-1-bromo-2-propanol, the bromine atom is attached to the first carbon atom. When this compound is treated with sodium hydroxide, the hydroxide ion attacks the carbon atom attached to the bromine atom and forms a negatively charged oxygen atom.This negatively charged oxygen atom further attracts the proton of the adjacent carbon atom (second carbon atom). After the transfer of a proton, the negatively charged oxygen atom gets neutralized and an alkoxide ion is formed. This alkoxide ion further attacks the third carbon atom and the compound is formed.In the compound obtained, there is no plane of symmetry or center of symmetry. This makes the compound optically active.

describe or determine the effect of temperature of temperature on reaction rate and activation energy for a reaction using the arrhenius equation

Answers

The Arrhenius equation shows that the activation energy is directly proportional to the logarithm of the rate constant and inversely proportional to the temperature.

The Arrhenius equation is

[tex]k = A e^{-\frac{E_a}{RT}}[/tex]

where:

k is the rate constant is the pre-exponential factor

Ea is the activation energy

R is the gas constant

T is the temperature in Kelvin

According to the Arrhenius equation, as temperature increases, the rate constant, and thus the reaction rate increases exponentially. This is because as temperature increases, the average kinetic energy of the molecules in the reaction mixture increases, leading to a greater proportion of molecules with sufficient energy to react.

The activation energy of a reaction, Ea, is the minimum energy required for reactant molecules to react and form products. The Arrhenius equation shows that the activation energy is inversely proportional to the rate constant, and thus the reaction rate. As temperature increases, the proportion of reactant molecules with sufficient energy to overcome the activation energy barrier increases, reducing the activation energy and increasing the reaction rate.

Overall, the Arrhenius equation demonstrates that increasing temperature increases the reaction rate and decreases the activation energy.

acqeous hydrocloric acid reacts with sodium hydroxide to prodcue acqueous sodium chloride and liquid water. what is the theoretical yield of water formed from the reaction of 34.3 g of hyrochloric acid and 72.6 g of sodium hydroxide

Answers

The theoretical yield of water formed from the reaction of 34.3 g of hydrochloric acid and 72.6 g of sodium hydroxide is 16.9 g.

The balanced chemical equation of the reaction can be written as follows:

HCl + NaOH → NaCl + H₂O

The reactants, hydrochloric acid (HCl) and sodium hydroxide (NaOH), are combined in a 1:1 mole ratio. This means that for every mole of HCl, one mole of NaOH is necessary to produce one mole of water and one mole of sodium chloride.

The molar mass of HCl and NaOH is 36.5 g/mol and 40.0 g/mol, respectively. Dividing their mass with their respective molar mass, we will have the number of moles of each reactant.

moles HCl = 34.3 g / 36.5 g/mol = 0.94 mol

moles NaOH = 72.6 g / 40.0 g/mol = 1.815 mol

Therefore, 34.3 g of HCl is equivalent to 0.94 moles, and 72.6 g of NaOH is equivalent to 1.82 moles.

Since these are in a 1:1 mole ratio, this reaction should produce 0.94 moles of water. The molar mass of water is 18.0 g/mol, and thus the theoretical yield of water produced is:

mass = moles x molar mass = 0.94 mol x 18 g/mol = 16.9 g.

in the solidifcation process the production of metallic slabs or ingots is known as the process of turning the metallic slabs or ingots into useful shapes is known as

Answers

The process of turning metallic slabs or ingots into useful shapes is known as "hot working" or "hot forming".

Hot working is a metalworking process where metals are shaped when they are above their recrystallization temperature. This process is usually done after a metal has been solidified from its molten state. It involves the application of force to change the shape of the metal, usually by compressing, drawing, forging, or extruding.

The temperature used during hot working can vary depending on the type of metal, but typically it must be at least half of the metal's melting point temperature. By hot working, the metal can be formed into various shapes, including thin sheets, rods, and tubes.

In the hot working process, the metal is heated until it reaches the recrystallization temperature and then deformed by mechanical means, such as hammering or rolling. The metal is then cooled down, either slowly or rapidly, depending on the required properties of the metal. Rapid cooling will increase the strength of the metal but also make it brittle, while slower cooling will give the metal more ductility. During cooling, some of the metal grains are recrystallized, leading to a homogeneous microstructure.

Hot working is an important process for many metal fabrication industries, including automotive, aerospace, and construction. It is used to create metal parts and components with superior strength and ductility, as well as for creating metal artworks or sculptures. The process is also widely used in metal recycling, where it is used to reshape and reform metals from their original form. Hot working can be a complex process and is typically done by highly skilled metalworkers.

how does 0.5 m sucrose 9mlecular mass 342) solution compare to 90.5 m glucose (molecular mass 180) solution

Answers

To compare the 0.5 M sucrose solution and the 90.5 M glucose solution, we need to consider their concentrations, which are measured in moles per liter (M).

For the 0.5 M sucrose solution, we know that it contains 0.5 moles of sucrose per liter of solution. The molecular mass of sucrose is 342 g/mol, so we can calculate the mass of sucrose in one liter of solution as follows:

0.5 moles/L × 342 g/mol = 171 g/L

Therefore, the 0.5 M sucrose solution contains 171 g of sucrose per liter of solution.

For the 90.5 M glucose solution, we know that it contains 90.5 moles of glucose per liter of solution. The molecular mass of glucose is 180 g/mol, so we can calculate the mass of glucose in one liter of solution as follows:

90.5 moles/L × 180 g/mol = 16,290 g/L

Therefore, the 90.5 M glucose solution contains 16,290 g of glucose per liter of solution.

From these calculations, we can see that the 90.5 M glucose solution is much more concentrated than the 0.5 M sucrose solution. However, the two solutions cannot be directly compared in terms of their effects on biological systems or their properties, as the properties of a solution depend on many factors such as solubility, osmotic pressure, and chemical interactions with other molecules.

The balanced chemical equation for the decomposition of hydrogen peroxide (H2O2) is:

2 H2O2 → 2 H2O + O2

This means that for every 2 moles of hydrogen peroxide, 1 mole of oxygen gas is produced. So to calculate the number of moles of O2 produced when 1.62 moles of H2O2 decompose, we need to use a proportion:

2 mol H2O2 : 1 mol O2 = 1.62 mol H2O2 : x mol O2

where "x" is the number of moles of O2 produced.

To solve for "x", we can cross-multiply and simplify:

2 mol H2O2 * x mol O2 = 1 mol O2 * 1.62 mol H2O2

2x = 1.62

x = 0.81

Therefore, 0.81 moles of O2 would be produced if 1.62 moles of H2O2 were to undergo decomposition.

what metal hydride reducing agent is used in this experiment? what product would be formed if catalytic hydrogenation with h2 were used?

Answers

The metal hydride reducing agent used in this experiment is sodium borohydride (NaBH₄).

If catalytic hydrogenation with H2 were used, the product would be an alkane with a double bond reduced to a single bond.

Sodium borohydride (NaBH₄) is a strong reducing agent capable of reducing aldehydes and ketones to their corresponding alcohols. It works by donating protons to the carbon-oxygen double bond, leading to the formation of an alkoxide intermediate.

The alkoxide is then reduced to the corresponding alcohol by hydrogen transfer from the hydride ion. Catalytic hydrogenation with H₂ will reduce the double bond to a single bond, producing an alkane product.

This process is used to produce a range of organic products in the laboratory, and is a very useful tool in organic synthesis.
