Answer:

8 moles of C

Explanation:

From the question given above, the following equation was obtained:

3A + 2B —> 6C

From the equation above,

3 moles of A reacted to produce 6 moles of C.

Thus, the number of mole of C produced by reacting 4 moles of A can be obtained as follow:

From the equation above,

3 moles of A reacted to produce 6 moles of C.

Therefore, 4 moles of C will react to produce = (4 × 6)/3 = 8 moles of C

Thus, 8 moles of C can be obtained from the reaction of 4 moles of A with excess B

Answer:

\(m_{CO_2}=75.6gCO_2\)

Explanation:

Hello there!

In this case, according to the given information, it turns out mandatory for us to calculate the reacting moles of both C and O2 because we are given grams and pressure, temperature and volume, respectively:

\(n_C=36gC*\frac{1molC}{12gC}=3.0molC \\\\n_{O_2}=\frac{3.0atm*14L}{0.08206\frac{atm*L}{mol*K}*298K}=1.72molO_2\)

Thus, since C and O2 react in a 1:1 mole ratio, we infer C is in excess, and the grams of CO2 can be calculated with the moles of O2:

\(m_{CO_2}=1.72molO_2*\frac{1molCO_2}{1molO_2}*\frac{44.01gCO_2}{1molCO_2} \\\\ m_{CO_2}=75.6gCO_2\)

They appear as the trait over a recessive allele. Statement C) is true about the dominant alleles.

Dominant alleles are genetic variants that, when present in an individual's genotype, are expressed phenotypically, meaning they determine the visible or observable traits. Dominant alleles are represented by capital letters, while recessive alleles are represented by lowercase letters in genetics.

In terms of inheritance, if an individual has at least one copy of the dominant allele, it will be expressed in the phenotype, regardless of the presence of a recessive allele. This is because dominant alleles exert their influence over recessive alleles, thus "dominating" their expression.

To illustrate this, let's consider a specific example using a trait controlled by a single gene with two possible alleles: dominant (A) and recessive (a). If an individual is homozygous dominant (AA), meaning they possess two copies of the dominant allele, the dominant trait will be expressed.

However, if an individual is homozygous recessive (aa), with two copies of the recessive allele, the recessive trait will be expressed since there are no dominant alleles to override it.

Therefore, dominant alleles appear as the trait over recessive alleles, regardless of the presence or absence of a recessive allele. The presence of even a single copy of the dominant allele is sufficient for its expression in the phenotype. Option C

Explanation:

The Method of Mixtures Electrical Method is a method used to determine the electrical conductivity of a material.

The Electrical Method is a geophysical prospecting technique that uses electrical resistivity to map subsurface features, such as geological structures, fractures, and mineral deposits.

It involves measuring the amount of current that passes through a mixture of two materials under the application of a known voltage. The electrical conductivity of each material can then be determined by calculating the ratio of the current to the applied voltage. The electrical conductivity obtained from the Method of Mixtures Electrical Method can be used to characterize materials such as semiconductors and insulators.

Chemistry => Thermochemistry => Exothermic and Endothermic Processes

The type of chemical reaction will depend on whether the reaction absorbs or releases energy.

When the reaction releases energy, it is because there is an excess of it and it is called exothermic. This excess occurs because the energy of the products is lower than that of the reactants.

Now, when the products have more energy than the reactants, it means that the reaction needs energy since there is a lack of energy. We call these types of reactions endothermic.

Now, according to the establishment, if the reactants have less energy (or enthalpy), it means that heat must be adsorbed in order to obtain the products that have higher energy (or enthalpy).

Therefore, the answer will be:

B. heat energy is absorbed

Abiotic factors are the non-living portions of an ecosystem and we know that sand is also non-living.

These include rocks, sand, shells, sunlight, temperature, and wind. In general, deserts are made up of several abiotic components – including sand, the lack of moisture, and hot temperatures – primarily anything that produces up an ecosystem that isn't living. An abiotic factor is a non-alive part of an ecosystem that shapes its environment. An ecosystem, for example, might include temperature, light, and water.

In a sea ecosystem, abiotic factors would include saltiness and ocean currents. Abiotic and biotic factors work jointly to create a unique ecosystem. In biology, the abiotic elements can absorb water, light, radiation, temperature, humidity, atmosphere, acidity, and soil. The observable climate often influences each of the above.

The exit gas stream average molecular weight is 28.97 g/mol, and there will be 3.0 kg of leftover Phenanthrene in the reactor.

The balanced combustion equation for Phenanthrene is:

C₁₄H₁₀ + 21O₂ → 14CO₂ + 5H₂O

From the equation, we can see that 21 moles of oxygen are needed to combust 1 mole of Phenanthrene. Thus, to burn 10 kg of Phenanthrene, we need:

and

However, the supplied air is 30% less than the requirement, which means only 70% of the required O₂ will be supplied. Therefore, the actual amount of O₂ supplied will be:

Assuming the air is mostly nitrogen, we can calculate the exit gas stream average molecular weight using the following formula:

where 0.79 and 0.21 are the mole fractions of nitrogen and oxygen in air, respectively, and 28.01 and 32 are the molecular weights of nitrogen and oxygen, respectively.

Finally, we can calculate the amount of leftover Phenanthrene in the reactor:

However, this amount is negligible due to the large scale of the reaction. Therefore, we can round it off to:

To graph the function g(x) = f(-x), you can start with the graph of f(x) and then reflect it about the y-axis.

To find the graph of the function g(x) = f(-x), we can start with the graph of the function f(x) and then reflect it about the y-axis.

If the graph of f(x) is symmetric with respect to the y-axis, meaning it is unchanged when reflected, then g(x) = f(-x) will have the same graph as f(x).

However, if the graph of f(x) is not symmetric with respect to the y-axis, then g(x) = f(-x) will be a reflection of f(x) about the y-axis.

The product of the reaction is attached.

The reaction provided in the equation is an electrophilic addition reaction. Electrophilic addition refers to a reaction between an electrophile and nucleophile, adding to double or triple bonds. In the given reaction, alkene is converted into neutral alcohol. As an alkene is treated with the reagent (Hg(OAc)₂, NaBH), the product obtained will be alcohol. This type of reaction is called oxymercuration- demercuration reaction.

In the reaction, the addition of water can occur without acidic conditions. In the presence of reagent mercury (II) acetate cyclic mercurinium ion will form, called . Following this, the reagent will reduce, a reaction called demercuration reaction. Together, this is called oxymercuration- demercuration reaction. As Mercury(II) acetate contains empty d- orbitals it will act as an electrophile and as alkene contains a double bond that will act as a nucleophile. They will form cyclic mercurinium ion and Hg-OAC will be released. In the presence of water hydroxide, the ion will attach on most substituted carbon.

Answer:

When HCl is added to aqueous solution of sodium sulphate aqueous solution, sulfuric acid is formed, and the solution's chemical makeup and acidity get changed.

Thus, several chemical reactions happen when HCl is introduced to a sodium sulphate aqueous solution. While sodium sulphate breaks down into 2 Na+ ions and SO4^2- ions, HCl splits into H+ and Cl- ions. When the H+ ions from HCl interact with the SO4^2- ions, sulfuric acid, a more potent acid, is created.

The solution's H+ ion concentration rises as a result of this reaction, altering the equilibrium in favor of the products. As a result, the system's equilibrium is upset, which causes sulfuric acid to form. The solution's chemical makeup and acidity ultimately alter as a result of the addition of HCl.
