Explanation:

p32 is a radioactive isotope with a half-life of 14.3 days. if you currently have 74.7 g of p32, 162g of p32 was present 8.00 days ago.

P32 has a 14.3-day half-life, which implies that every 14.3 days, the amount of P32 will be cut in half.

First, let's determine how many half-lives have passed in eight days:

Time elapsed ÷ by half-life (8.00 days) × half-life (14.3 days) results in 0.559 half-lives.

Therefore, 0.559 half-lives have passed after 8.00 days.

Now, we can use the calculation below to determine how much P32 was present 8.00 days ago:

N = N0 × (1/2)^(t/t1/2)

where: N0 = P32's original amount

N is the amount of P32 at time t, where t1/2 is its half-life.

t is the passing of time.

We can plug in the data and solve for N0 because we know that the current concentration of P32 is 74.7 g:

N0 = 74.7 g (1/2) (0.559 14.3 days 14.3 days)

74.7 g = N0 × (1/2)^0.559

(Rounded to three major values) N0 = 163 g

Thus, 163 g of P32 were present eight days prior.

The phenomenon described in the given question, where some amount of the solid stuck to the weigh paper and was not transferred, is an example of a volumetric error in the preparation of standard solutions.

A standard solution is a solution with a precisely known concentration of an element or a substance. They are prepared to a specific concentration by dissolving a known quantity of a pure substance in a particular solvent in a volumetric flask.

Volumetric errors are a type of systematic error that occurs when preparing standard solutions. They occur due to an error in the volume of solution added or when some of the solute gets lost during the transfer process. As a result, the measured concentration comes out a bit low for this solution.

To avoid such errors, it is essential to pay close attention to the precise amount of the analyte used and be careful while transferring it to the volumetric flask. Any loss of the solid during the transfer process will result in an incorrect concentration of the solution and can lead to incorrect results.

Thus, the correct answers is volumetric error.

Answer:

v = 78.5 km/h

Explanation:

It is given that, the distance between one city to another is 314 km. The overall trip takes 4 hours. We need ton find average velocity. It is equal to the total displacement divided by total time taken. So,

\(v=\dfrac{d}{t}\\\\v=\dfrac{314\ km}{4\ h}\\\\v=78.5\ km/h\)

So, average velocity is 78.5 km/h.

Answer:

Explanation: Elements in group 14 have 4 valence electrons. Meaning that to achieve a stable octet they need to either gain or lose 4 electrons in total. That would take significantly more energy than other elements, e.g., group 1 (alkaline metals) or group 17 (halogens.)

Explanation:

In the periodic table, the elements in column 4 have four valence electrons and are less reactive compared to s- block elements but more reactive than the p-block elements.

Periodic table is a tabular arrangement of elements in the form of a table. In the periodic table, elements are arranged according to the modern periodic law which states that the properties of elements are a periodic function of their atomic numbers.

It is called as periodic because properties repeat after regular intervals of atomic numbers . It is a tabular arrangement consisting of seven horizontal rows called periods and eighteen vertical columns called groups.

Elements present in the same group have same number of valence electrons and hence have similar properties while elements present in the same period show gradual variation in properties due to addition of one electron for each successive element in a period.

Answer:

Thus, we can say that the element is calcium. This can be clearly understood as ionic compounds have high melting and boiling points in general such as calcium oxide.

Answer:

The element is Calcium I guess.

Explanation:

Cause calcium oxide has high melting point and is soluble in water.

Although two bodies can have the same amount of "energy," "enthalpy," or "internal energy," they cannot have the same amount of "heat."

When two bodies' molecules have different kinetic energies, "heat" is the amount of energy that transfers from one to the other.

These kinetic energies are measured in terms of temperature.

Using the temperature change as an example, Q = m * c *.

The amount of heat transferred is the same if we take identical blocks of the same substance and heat them up to 25 C and 29 C, respectively. However, even though their final temperatures are different, the amount of heat transferred is the same.A thermodynamic system's internal energy and the product of its pressure and volume are added to form enthalpy, which is one of the system's properties. It is a state function that is frequently used to measure chemical, biological, and physical systems at a constant pressure that is conveniently provided by the sizable surrounding atmosphere. Because energy is being released from the system in the form of heat, this is an example of an exothermic reaction. Refrigerator compressors are a different application of enthalpy. Again, under the exact same conditions of constant pressure, a vaporization reaction is taking place here.

Option (d), P=ATC=MR=MC, accurately represents the long-run equilibrium condition for perfect competition, reflecting the balance between price and cost for firms operating in a competitive market.

The long-run equilibrium condition for perfect competition is that price (P) is equal to average total cost (ATC), which is also equal to marginal cost (MC), and marginal revenue (MR).

Option (d), P=ATC=MR=MC, best represents the long-run equilibrium condition for perfect competition. In perfect competition, firms operate at the minimum point of their average total cost curve, where price equals both average total cost and marginal cost. This condition ensures that firms are earning zero economic profit and are producing at an efficient level.

In the long run, if firms are earning economic profit, new firms will enter the market, increasing competition and driving prices down. Conversely, if firms are experiencing losses, some firms may exit the market, reducing competition and causing prices to rise. This process continues until firms reach a state where price equals average total cost, marginal cost, and marginal revenue, ensuring a long-run equilibrium.

Therefore, option (d), P=ATC=MR=MC, accurately represents the long-run equilibrium condition for perfect competition, reflecting the balance between price and cost for firms operating in a competitive market.

The best two elution fractions to pool together for the application to a subsequent column would be the ones with the highest protein concentrations, regardless of whether they are adjacent to each other or not.

Based on the quantitative data, the best two elution fractions to pool together for the application to a subsequent column would be the fractions that have the highest protein concentration. This would ensure that the subsequent column would be able to effectively purify the desired protein.

In order to determine the best two elution fractions to pool together, you would need to look at the data for each fraction and compare the protein concentrations. The fractions with the highest protein concentrations would be the best ones to pool together for the application to a subsequent column.

It is important to note that the best two elution fractions may not necessarily be adjacent to each other.

To find the Br-Br bond energy, we need to use the bond energy values given in the table and apply Hess's law.

First, we need to write the balanced equation for the reaction:

H2(g) + Br2(g) → 2HBr(g)

Next, we can calculate the bond energies for the bonds broken and formed in the reaction:

Bonds broken:
1 mol H-H bonds x 435 kJ/mol = 435 kJ/mol
1 mol Br-Br bonds x ? kJ/mol = ? kJ/mol

Bonds formed:
2 mol H-Br bonds x 362 kJ/mol = 724 kJ/mol

Using Hess's law, we know that the sum of the bond energies for the bonds broken must equal the sum of the bond energies for the bonds formed plus the overall energy change for the reaction:

Bonds broken = Bonds formed + ΔH

Substituting in the bond energies we calculated and the given ΔH value of -36.44 kJ/mol:

435 kJ/mol + ? kJ/mol = 724 kJ/mol - 36.44 kJ/mol

Simplifying:

? kJ/mol = (724 kJ/mol - 435 kJ/mol) - (-36.44 kJ/mol)
? kJ/mol = 312.56 kJ/mol

Therefore, the Br-Br bond energy is approximately 313 kJ/mol or 313,000 J/mol.

The answer is not one of the choices given, but it is closest to option (a) 399 kJ/mol.
