Explanation:
The given data is as follows.
Mass of apple sauce mixture = 454 kg
Heat added (Q) = 121300 kJ
Heat capacity (
) of apple sauce at
= 4.0177
So, Heat given by heat exchanger = heat taken by apple sauce
Q = ![mC_{p} \Delta T](https://tex.z-dn.net/?f=mC_%7Bp%7D%20%5CDelta%20T)
or, Q =
Putting the given values into the above formula as follows.
Q =
121300 kJ = ![454 kg \times 4.0177 kJ/kg^{o}C \times (T_{f} - 10)](https://tex.z-dn.net/?f=454%20kg%20%5Ctimes%204.0177%20kJ%2Fkg%5E%7Bo%7DC%20%5Ctimes%20%28T_%7Bf%7D%20-%2010%29)
= ![76.5^{o}C](https://tex.z-dn.net/?f=76.5%5E%7Bo%7DC)
Thus, we can conclude that outlet temperature of the apple sauce is
.
An example of a reaction that occurs within the core of a nuclear reactor is the nuclear fission reaction given:
- ²³⁵₉₂U + ¹₀n ---> ⁹⁰₃₈Sr + ¹⁴³₅₄ + 3 ¹₀n
<h3>What is a nuclear reactor?</h3>
A nuclear reactor is a device which produces electrical energy as a result of the nuclear reactions that take place within it.
In a nuclear reactor, the reaction that takes place within the core is a nuclear fission chain reaction.
In a nuclear fission reaction, the nucleus of larger atoms are split into the nucleus of smaller atoms when fast moving neutrons are used to bombard the nucleus of the large atom. The fission of the nucleus of the large atom results in the formation of atoms of lighter nucleus as well as more protons which then bombard more nucleus of the large atoms resulting in a chain reaction.
The chain reaction occurring within the nuclear reactor core is controlled by the insertion of boron rods which absorbs the excess neutrons produced.
An example of a reaction that occurs within the core of a nuclear reactor is given below:
²³⁵₉₂U + ¹₀n ---> ⁹⁰₃₈Sr + ¹⁴³₅₄ + 3 ¹₀n

Answer:
weak bonds break and strong bonds form
Explanation:
An exothermic reaction is a chemical reaction in which heat energy is evolved during the reaction process.
Bond formation requires energy while bond breakage releases energy. More energy is needed for the formation of weak bonds as compared to strong bonds.
<em>Hence, when weak bonds break, they release more energy than needed to make a corresponding strong bond leading to the release of the remaining energy as heat.</em>
212 ml of lead nitrate is required to prepare a dilute solution of 820.7 ml of lead nitrate.
Answer:
Option A.
Explanation:
Similar to Avagadro's law, there is another law termed as dilution law. As the product of volume and normality of the reactant is equal to the product of volume and normality of the product from the Avagadro's law. In dilution law, it will be as product of volume and concentration of the solute of the reactant is equal to the product of volume and concentration of solution.
![C_{1} V_{1} =C_{2} V_{2}](https://tex.z-dn.net/?f=C_%7B1%7D%20V_%7B1%7D%20%3DC_%7B2%7D%20V_%7B2%7D)
So, as per the given question C1 = 5.45 M of lead nitrate and V1 has to be found. While C2 is 1.41 M of lead nitrate and V2 is 820.7 ml.
Then, ![(5.45*V_{1} ) = (820.7*1.41)](https://tex.z-dn.net/?f=%285.45%2AV_%7B1%7D%20%29%20%3D%20%28820.7%2A1.41%29)
![V_{1}=\frac{820.7*1.41}{5.45}= 212.33 ml](https://tex.z-dn.net/?f=V_%7B1%7D%3D%5Cfrac%7B820.7%2A1.41%7D%7B5.45%7D%3D%20%20212.33%20ml)
So nearly 212 ml of lead nitrate is required to prepare a dilute solution of 820.7 ml of lead nitrate.
