The element phosphorous (P) has an atomic number of 15 and an atomic mass of 31. How many neutrons are in an atom of
phosphorous (P)? (1 point)
O 15
O 16
O 31
O 46
Answers
The correct answer is 16 that is the element Phosphorous has 16 neutrons.
The neutron is known as a subatomic particle that is slightly heavier than a proton and has a neutral charge (one that is neither positive nor negative). Atomic nuclei consist of both protons as well as neutrons.
Protons and neutrons both are referred to as "nucleons" because of how similarly they function inside the nucleus and because they both have masses that are about equal to one atomic mass unit.
Nuclear physics explains their interactions and characteristics. Each proton and neutron is made up of three quarks, hence they are not fundamental particles.
The arrangement of electrons around an atom's heavy nucleus mostlydetermines its chemical characteristics. The atomic number, or we can say number of protons, which determines the charge of the nucleus, determines the electron configuration.

Answers
Internal energy change = 496 kJ + (101.32 J * 1020 L) = 507.6 kJ
What is Internal energy change ?Internal energy change is the difference between the total energy of a system before and after a process has taken place. It is a measure of the amount of energy which has been added or removed from the system. Internal energy is made up of two components: the kinetic energy of the molecules, atoms, and particles within the system, and the potential energy associated with their relative positions and interactions with each other. Internal energy change can be measured by calculating the difference between the energy of the system before and after the change has taken place. This includes changes in temperature, pressure, volume, and chemical composition, as well as the addition or removal of energy from the system. Internal energy change can be used to measure the efficiency of a process, as well as to predict the energy required to achieve a desired change.

A tank initially contains 60 gal of pure water. Brine containing 1lb of salt per gallon enters the tank at 2gal/min, and the (perfectly mixed) solution leaves the tank at 3gal/min; thus the tank is empty after exactly 1 hour. Let y(t) be the amount of salt in the tank after t minutes. (a) Write an Initial Value Problem for the amount of salt in the tank at any time t<60). (b) Solve the IVP in part (a) to find the amount of salt in the tank at any time t<60). (c) Determine the amount of salt when the tank is half empty.
Answers
(a) Writing an Initial Value Problem for the amount of salt in the tank at any time t<60)Initial Value Problem (IVP) is a differential equation accompanied by initial conditions. The differential equation we will use is:
y′(t) = 2(1 − y(t)/V) − 3y(t)/Vwhere V is the volume of the tank and y(t) is the amount of salt in the tank at time t. The initial condition will be y(0) = 0(b) Solving the IVP in part (a) to find the amount of salt in the tank at any time t<60)To solve this differential equation, we can use the integrating factor method. The integrating factor is:
IF = e^(3t/V)Multiplying both sides by the integrating factor, we get:e^(3t/V) y′(t) + 3/V e^(3t/V) y(t) = 2e^(3t/V) − 2y(t)/V(e^(3t/V) y(t))′ = 2e^(3t/V)We integrate both sides with respect to t:(e^(3t/V) y(t)) = (2/3) e^(3t/V) + Cwhere C is the constant of integration. Using the initial condition, we find that:C = (2/3) e^0 = 2/3Therefore, the solution is:e^(3t/V) y(t) = (2/3) e^(3t/V) + (2/3)e^0y(t) = (2/3) + (2/3)e^(-3t/V)(c) Determining the amount of salt when the tank is half emptyThe tank is half empty when there is 30 gallons of solution in it. Since the tank is emptied in one hour, this happens when there is 30 gallons of brine in the tank. Therefore, the amount of salt in the tank when it is half empty is:y(60) = (2/3) + (2/3)e^(-3 × 60/V)We need to find V to solve for y(60). We know that the tank starts with 60 gallons of water, and 1 gallon of brine enters every minute and 3 gallons of solution leave every minute. Therefore, the volume of the tank is:
V = 60 + (1 − 3) t = 60 − 2tWhen t = 60, V = 60 − 2 × 60 = −60Therefore, the tank does not have a volume of −60. Instead, the problem has an error.About SaltSalt is a collection of chemical compounds with the main component Sodium Chloride (NaCL) being the same as table salt.

mog- ab associated demyelinating disease mimicking typical ms: a case for expanding anti-mog testing
Answers
MOG-AB associated demyelinating disease is a condition that resembles typical multiple sclerosis (MS) but involves the presence of anti-MOG antibodies.
What is the significance of expanding anti-MOG testing in diagnosing and managing this condition?Expanding anti-MOG testing is crucial in diagnosing and managing MOG-AB associated demyelinating disease for several reasons. Firstly, distinguishing this condition from typical MS is essential as their treatment approaches differ. While typical MS is primarily managed with disease-modifying therapies, MOG-AB associated demyelinating disease often requires immunosuppressive agents to target the pathogenic antibodies. Accurate diagnosis prevents unnecessary treatments and improves patient outcomes.
Additionally, MOG-AB associated demyelinating disease can manifest with atypical clinical features and different radiological patterns compared to typical MS. Therefore, comprehensive testing for anti-MOG antibodies helps identify patients who may benefit from alternative diagnostic and therapeutic strategies.
Furthermore, recognizing the presence of anti-MOG antibodies aids in predicting disease course and prognosis. Patients with MOG-AB associated demyelinating disease may have a higher likelihood of relapses and optic neuritis but a lower risk of developing long-term disability compared to MS patients. Tailoring management plans based on this information allows for personalized care.

answer not here
Answers
The new concentration of the barium chloride solution, after diluting 78.4 mL of a 0.85 M solution to a final volume of 350 mL, is 0.19 M.
To calculate the new concentration, we can use the equation C₁V₁ = C₂V₂, where C₁ and V₁ are the initial concentration and volume, and C₂ and V₂ are the final concentration and volume. Given that C₁ = 0.85 M and V₁ = 78.4 mL, and V₂ = 350 mL, we can solve for C₂.
Rearranging the equation, we get C₂ = (C₁ × V₁) / V₂ = (0.85 M × 78.4 mL) / 350 mL ≈ 0.19 M. Therefore, the new concentration of the barium chloride solution, after diluting 78.4 mL of a 0.85 M solution to a final volume of 350 mL, is approximately 0.19 M.

a solution of x in water is prepared with a concentration of 0.053 moles of x in 10.0 ml of solution. a second solution of x in water is prepared to have a concentration of 0.53 moles of x in 100.0 ml of solution. what is true about the densities of the two solutions?
Answers
The true densities of the two solutions is: first solution will be denser than the second solution.
The density of the first solution will be higher than that of the second solution because the first solution contains a higher concentration of x (0.053 moles/10.0 mL) compared to the second solution (0.53 moles/100.0 mL). This means that the same mass of x occupies a smaller volume in the first solution, making it more dense than the second solution.
In terms of concentration, the first solution has a higher molarity than the second solution, as 0.053 moles of x are present in 10.0 mL of solution, compared to 0.53 moles in 100.0 mL of solution. The molarity is defined as moles of solute per liter of solution, which can be expressed as moles/mL.
Thus, the first solution has a concentration of 0.53 moles/10.0 mL and the second solution has a concentration of 0.53 moles/100.0 mL. As the concentration of solute increases, the density of the solution also increases. This is because the same mass of solute will occupy a smaller volume, making it more dense than a solution with a lower concentration of the same solute.
Therefore, since the first solution has a higher concentration than the second solution, the first solution will be denser than the second solution.

Answers
After solving the problem the final volume of the gas is 35L.
What is final volume?The final volume is the amount of space occupied by an object, gas, or liquid in its finished state. It is the total volume of a substance, regardless of any changes that may have occurred to it during a process.
The final volume of the gas can be calculated using the ideal gas law. The ideal gas law states that:
PV = nRT
where P is pressure, V is volume, n is the amount of substance, R is the ideal gas constant and T is temperature.
Since this is an isothermal process, the temperature is constant and can be cancelled out. We can rearrange the equation to:
V2 = V1 (P2/P1)
where V2 is the final volume and V1 is the initial volume.
Substituting in the values, we get:V2 = 20L (1.75/1.00)
V2 = 35L

Putting values in equation (i), we get:
\(q_2=50g\times 1Cal/g^oC\times (100-0)\\\\q_2=5000Cal\)
For process 3:We are given:
\(m=50.0g\\\Delta H_{vap}=540Cal/g\)
Putting values in equation (i), we get:
\(q_3=50.0g\times 540J/g\\\\q_3=27000Cal\)
Calculating the total amount of heat released:
\(Q=q_1+q_2+q_3\)
\(Q=[(4000)+(5000)+(27000)]Cal=36000Cal=36.0\times 10^3Cal\)
Hence, the amount of heat absorbed is \(36.0\times 10^3Cal\)
