The minimum kinetic energy a neutron must possess to initiate the 6Li(n,p)6He reaction is 977.51 MeV or 1.56 × 10-13 J.

The minimum kinetic energy a neutron must possess to allow the reaction 6Li (n, p) 6He to occur is known as the threshold energy of the reaction. The threshold energy is the minimum amount of energy required to initiate a nuclear reaction.

The reaction 6Li(n,p)6He is a nuclear reaction that converts lithium-6 into helium-4 and a proton. The reaction takes place when a neutron with a minimum kinetic energy collides with lithium-6, causing it to break apart.The threshold energy for the 6Li(n,p)6He reaction can be calculated using the conservation of energy principle.

The conservation of energy states that the total energy of a system remains constant if no external forces act upon it. In this case, the energy of the neutron must be equal to the sum of the binding energy of lithium-6 and the kinetic energy of the proton produced from the reaction.

The binding energy of lithium-6 is 39.24 MeV, and the mass of a proton is 1.0073 u.

Using these values, the threshold energy can be calculated as follows:

Threshold energy = Binding energy of 6Li + kinetic energy of proton

Threshold energy = 39.24 MeV + (1.0073 u)(931.5 MeV/u)

Threshold energy = 39.24 MeV + 938.27 MeV

Threshold energy = 977.51 MeV

Therefore, the minimum kinetic energy a neutron must possess to initiate the 6Li(n,p)6He reaction is 977.51 MeV or 1.56 × 10-13 J.

This problem is providing information about the loss of mass for a reaction 50 °C as a function of the time elapse. Thus, when taking a look at the given graph, we can trace a horizontal line on the y-axis at 0.95 g in order to intercept it with the curve, and hence, figure out the time at which that loss of mass takes place.

Thus, we can see that when the loss of mass hits 0.95 g, the corresponding time on the graph is about 80 seconds, and hence, the rate of reaction turns out to be:

\(r=\frac{0.95g}{80s}\\\\r=0.012\frac{g}{s}\)

Which has two significant figures as required.

The volume of bromine that is required to react with 165 liters of chlorine gas is 49.8 L.

(1) volume of chlorine=33.8 liters

Given reaction equation: Br2(g)+Cl2(g) -> 2BCl(g)

In case of gases, molar ratio can be expressed in terms of volume occupied by each gas at constant temperature and pressure.(volume is directly proportional to number of moles of gas).

According to the balanced reaction, moles of bromine =moles of chlorine=33.8 L

Hence volume of bromine required = 33.8 litres

(2)according to given reaction:

2BrF3 (g) -> Br2(g)+3F2(g)

total moles of product =4

reactant=2

Hence ratio of moles of reactant: product=2:4 i.e., 1:2.

so, total volume of product = 2 * volume of reactant(BrF3)=2*24.9L = 49.8 liters

Aufbau states that you must fill the lowest energy orbital 3d before 4s but we fill 4s before 3d because 3d orbitals have slightly more energy than 4s orbitals.

In atomic theory and quantum mechanics, an atomic orbital is a feature describing the location and wave-like conduct of an electron in an atom. This feature may be used to calculate the possibility of locating any electron of an atom in any specific location across the atom's nucleus.

An atomic orbital is a mathematical term in atomic concept and quantum mechanics that describes the location and wavelike behavior of an electron in an atom. Most of the electrons, each with its own spin quantum quantity s, will occupy every one of these orbitals.

Orbital holds electrons that range in an asset called spin. Orbital: A area of space within an atom in which an electron in a given subshell can be found. Any orbital can preserve most of the 2 electrons with contrary spin. the primary shell has one 1s orbital and holds 2 electrons.

Answer:  \(6.047\times 10^{23}\) atoms in 1.004 mol of arsenic

Explanation:

According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number \(6.023\times 10^{23}\) of particles.

To calculate the atoms, we use the equation:

\(\text{Number of moles}=\frac{\text{Given atoms}}{\text {avogadro's number}}\)

\(1.004=\frac{x}{6.023\times 10^{23}}\)

\(x=1.004\times 6.023\times 10^{23}=6.047\times 10^{23}\)

Thus there are \(6.047\times 10^{23}\) atoms in 1.004 mol of arsenic

The price of mercury used to make one manometer is $2.600X, and the price of mercury used to make 15 manometers is $39.00X, where X represents the cost of mercury per cubic inch.

To find the price of the mercury used to make one manometer, we need to know the cost of mercury per cubic inch. Once we have that information, we can calculate the cost for one manometer by multiplying the volume of mercury used (2.600 in^3) by the cost per cubic inch.

Let's assume the cost of mercury is $X per cubic inch.

Price of mercury used to make one manometer = Volume of mercury used * Cost per cubic inch

= 2.600 in^3 * $X/in^3

= $2.600X

Now, to find the price of mercury used to make 15 manometers, we can multiply the cost of one manometer by the number of manometers.

Price of mercury used to make 15 manometers = Price of one manometer * Number of manometers

= $2.600X * 15

We need to add 0.43 moles of NaOH to the buffer. This is equivalent to adding 2.59 L of 6.01 M NaOH to the buffer.

To calculate the amount of 6.01 M NaOH required to raise the pH of the buffer, we first need to determine the current pH of the buffer. Using the Henderson-Hasselbalch equation, we can calculate that the pH of the buffer is 4.76. To raise the pH to 5.75, we need to add enough NaOH to increase the [OH-] concentration by a factor of 10.

This means we need to add 10 times the amount of H+ ions in the buffer solution. From the balanced chemical equation for the ionization of acetic acid, we know that for every mole of acetic acid that ionizes, it produces one H+ ion. Therefore, we need to add 0.43 moles of NaOH to the buffer. This is equivalent to adding 2.59 L of 6.01 M NaOH to the buffer.

He will arrive at the second city on time

Using the formula for calculating speed expressed as:

Distance = Speed * time

Given the following parameters

Speed = 65km/hr

Time = 3 hours (from noon to 3PM)

Get the distance covered by Isaiah;

Distance = 65 * 3

Distance = 195km > 186km

Since the distance covered by Isaiah is greater than the distance from one city to another city, hence he will arrive at the second city on time

What is Speed?

The speed at which an object's location changes in any direction. The distance traveled in relation to the time it took to travel that distance is how speed is defined. Since speed simply has a direction and no magnitude, it is a scalar quantity.

Therefore,

186km at 3:00 the speed limit is 65km/h
