1 answer:
<u>Answer:</u> 3 neutrons are produced in the above nuclear reaction.
<u>Explanation:</u>
In a nuclear reaction, the total mass and total atomic number remains the same.
The nuclear reaction for the fission of Americium-244 isotope follows:
<u>To calculate Y:</u>
Total mass on reactant side = total mass on product side
Hence, 3 neutrons are produced in the above nuclear reaction.

Answer : The equilibrium concentration of at
is,
.
Solution : Given,
Equilibrium constant,
Initial concentration of = 0.260 m
Let, the 'x' mol/L of are formed and at same time 'x' mol/L of
are also formed.
The equilibrium reaction is,
Initially 0.260 m 0 0
At equilibrium (0.260 - x) x x
The expression for equilibrium constant for a given reaction is,
Now put all the given values in this expression, we get
By rearranging the terms, we get the value of 'x'.
Therefore, the equilibrium concentration of at
is,
.
Answer:
The final temperature is 397 K.
Explanation:
Boyle's law relates volume and pressure by expressing:
"The volume occupied by a certain gaseous mass at constant temperature is inversely proportional to pressure"
Boyle's law is expressed mathematically as:
P * V = k
where k is a constant.
Charles's Law consists of the relationship between the volume and the temperature of a certain amount of ideal gas, which is kept at a constant pressure. This law states: "At constant pressure, the volume that a gas sample occupies is directly proportional to the temperature"
So, Charles's law is a law that says that when the amount of gas and pressure are kept constant, the ratio between the volume and the temperature will always have the same value:
Finally, Gay-Lussac's law establishes the relationship between pressure and temperature of a gas when the volume is constant. This law states that the pressure of a fixed volume of a gas is directly proportional to its temperature. That is, if the volume of a certain quantity of ideal gas at moderate pressure is kept constant, the quotient between pressure and temperature remains constant.
Combined law equation is the combination of three gas laws called Boyle's, Charlie's and Gay-Lusac's law. So, you have:
Supposing you have a gas that is at a pressure P1, at a volume V1 and at a temperature T1 at the beginning of the experiment, by varying the temperature to a new value T2, then the pressure will change to P2 and the volume to V2, and will fulfill:
In this case, you have:
- P1= 0.750 kPa
- V1= 2 L
- T1= 25°C= 298 °K (being 0°C=273°K)
- P2= 0.500 kPa
- V2= 4 L
- T2= ?
Replacing:
and solving you get:
T2= 397 K
<u><em>The final temperature is 397 K.</em></u>
