Explanation:

The atomic mass of Sulphur is 80.1 amu ≈ 80 amu.

Atomic mass, also known as average mass in a bunch of atoms, is the total mass of the protons, neutrons, and electrons that make up an atom. However, because they are so much lighter than protons and neutrons, electrons are not taken into account in the computation. The mass of protons and neutrons together make up the atomic mass.

The mass of the elements present in the compound determines the percentage composition.

Sulfur mass equals 32.1 amu given

Oxygen mass = 16.0 amu

Sulfur trioxide mass is 32.1 + 3 × 16.0 = 80.1 amu.

Explanation:

The median reaction at the second end point in the HCl and NaOH titration is: HCl + NaOH → NaCl + H2O

In a titration between hydrochloric acid (HCl) and sodium hydroxide (NaOH), the reaction involved is the neutralization reaction between an acid and a base. The balanced equation for this reaction is:

HCl + NaOH → NaCl + H2O

In this reaction, one mole of HCl reacts with one mole of NaOH to form one mole of NaCl (sodium chloride) and one mole of water.

During the titration process, the reaction occurs gradually as the base is added to the acid solution.

The first end point of the titration is reached when the moles of HCl and NaOH are stoichiometrically equivalent, meaning they react in a 1:1 ratio. At this point, all the HCl has been neutralized by the NaOH, and no excess of either reagent remains.

However, if the titration is continued beyond the first end point, the reaction between HCl and NaOH can still occur, albeit in a different ratio.

The second end point refers to the point where the moles of NaOH added exceed the stoichiometrically required amount to neutralize the HCl completely. As a result, any excess NaOH added after the second end point reacts with the excess HCl in a 1:1 ratio.

Therefore, the median reaction at the second end point in the HCl and NaOH titration is:

HCl + NaOH → NaCl + H2O

Answer: 20.9 billion years.

Explanation: To estimate the age of the rock, we can use the fact that the half-life of uranium-238 is 4.47 billion years. This means that half of the uranium-238 in the rock would have decayed into lead-206 after 4.47 billion years, and half of what remains would decay in the next 4.47 billion years, and so on.

If 20% of the uranium-238 in the rock has decayed into lead-206, then 80% of the original uranium-238 is still present in the rock. This means that the rock has gone through one half-life of uranium-238 decay, and we can estimate its age by using the graph on page 253.

According to the graph, the ratio of lead-206 to uranium-238 after one half-life is approximately 0.027. This means that the rock contains 0.027 times as much uranium-238 as it did originally, and the remaining 80% of the uranium-238 corresponds to 0.8 times the original amount.

Therefore, we can estimate the original amount of uranium-238 in the rock as follows:

Original amount of uranium-238 = (0.8) / 0.027 = 29.63 times the current amount

Next, we can use the fact that each half-life corresponds to a reduction in the amount of uranium-238 by a factor of 2, to estimate the number of half-lives that have passed since the rock formed:

Number of half-lives = log2(29.63) = 4.88

Finally, we can estimate the age of the rock as follows:

Age of the rock = (4.88) x (4.47 billion years per half-life) = 20.9 billion years

Therefore, we can estimate that the age of the rock is approximately 20.9 billion years.

The correct answer to an enzyme is B) binds substrates in a manner that facilitates the formation of product.

Enzymes are biological catalysts that speed up chemical reactions in living organisms. They do this by binding to substrates (the reactants in a chemical reaction) and facilitating the formation of product.

This is done by lowering the activation energy required for the reaction to occur, making it easier for the reaction to take place. Enzymes do not change the position of the equilibrium of the reaction, nor do they decrease the rate of the reaction.

Enzymes also do not change the rate at which the equilibrium is achieved. Lastly, enzymes are not always proteins, as some RNA molecules can also function as enzymes. Therefore, the correct answer is B) binds substrates in a manner that facilitates the formation of product.

Kelly should line her koi fish pond with clay to ensure that no water leaks out through gravitational water flow.

Clay is a natural material that is used widely in pond and water feature construction. It has excellent water-holding properties and is able to form a waterproof seal when properly installed. Clay liners can be formed using either bentonite clay or kaolin clay, both of which are readily available and relatively inexpensive.

When installing a clay liner, it is important to prepare the pond base by removing any sharp or protruding objects, compacting the soil, and smoothing out any irregularities. The clay liner can then be laid down in layers and compacted to ensure a uniform thickness and a solid seal.

Overall, using a clay liner is an effective way to prevent water from leaking out of a koi fish pond and to maintain a healthy environment for the fish.

A pure substance is indeed a single kind of matter with a uniform and definite composition. In contrast, a mixture is made up of two or more substances that are together in the same place, but each substance maintains its own properties.

Mixtures can be classified as either homogeneous or heterogeneous. A homogeneous mixture has a uniform composition throughout, meaning its components are evenly distributed and not easily distinguishable. Examples include solutions, such as saltwater or air.

On the other hand, a heterogeneous mixture has an uneven distribution of its components, and its individual substances can be easily identified. Examples include sand and water, or oil and water.

One key distinction between a pure substance and a mixture is that a pure substance has a fixed composition, while the composition of a mixture can vary. This means that mixtures can be separated into their individual components through physical processes like filtration, evaporation, or distillation, without undergoing any chemical changes.

In summary, a pure substance is a single type of matter with a definite and uniform composition, while a mixture consists of two or more substances that are combined in the same place, but each substance retains its individual properties. Mixtures can be homogeneous or heterogeneous and can be separated into their components through physical methods.
