Answer:
-370.1 kJ/mol CpA = 84.5 J/(mol-K) CpB = 137 J/(mol-K) Cpc = 170 J/(mol-K) CpD = 75 J/(mol-K) To = 303 K FAo = 10 mol/min FBo = 30 mol/min v = 1000 L/min CAo =0.01 mol/L
Explanation:
The nitration of aromatic compounds is a highly exothetion that generally uses catalysts that tend to be corrosive (e.g., HNO3 /H2SO4 ). A less corrosive employs N2 O5 as the nitrating agent as illustrated below: If this reaction is conducted in an adiabatic CSTR, what is the reactor volume and space time necessary to achieve 35 percent conversion of N2O5? The reaction rate is first order in A and second order in B. Data: HRX = -370.1 kJ/mol CpA = 84.5 J/(mol-K) CpB = 137 J/(mol-K) Cpc = 170 J/(mol-K) CpD = 75 J/(mol-K) To = 303 K FAo = 10 mol/min FBo = 30 mol/min v = 1000 L/min CAo =0.01 mol/L

Plutonium-239 is used in nuclear bombs, here 239 is its mass number. For an atom, mass number is equal to sum of number of protons and neutrons.
Thus,
A=n+p=239...... (1)
From periodic table, the atomic number of plutonium is 94 which is equal to number of electron and proton in an atom.
Thus,
Z=p=94
Putting the value of p in equation (1)
n=239-94=145
The symbol is as follows:
Here, Z is atomic number, A is mass number and X is atom symbol thus, symbol for plutonium will be:
Therefore, number of protons, neutrons and symbol is 94, 145 and respectively.
Answer:
Explanation:
Hello,
In this case, the Boyle's is mathematically defined via:
Which stands for an inversely proportional relationship between volume and pressure, it means the higher the volume the lower the pressure and vice versa. In such a way, since the volume is decreased to one quarter, we can write:
We can compute the new pressure:
Which means the pressure is increased by a factor of four.

Traditionally, gunpowder used in fireworks was made of 75 percent potassium nitrate also called saltpeter mixed with 15 percent charcoal and 10 percent sulfur; modern fireworks sometimes use other mixtures (such as sulfurless powder with extra potassium nitrate) or other chemicals instead
A or D I think...sorry if it’s wrong
