![\Delta H=4.63x10^{5}J=463kJ](https://tex.z-dn.net/?f=%5CDelta%20H%3D4.63x10%5E%7B5%7DJ%3D463kJ)
Explanation:
Hello,
In this case, we find the following states:
a. Liquid salt water at 28.0 °C.
b. Liquid salt water at 102.5 °C.
c. Vapor salt water at 102.5 °C.
The first process (1) is to heat the liquid water from 28.0 °C to 102.5 °C and the second one (2) to vaporize the liquid salt water. In such a way, each process has an amount of energy that when added, yields the total energy for the process as shown below:
![\Delta H=\Delta H_1+\Delta H_2\\\Delta H=mCp\Delta T+m\Delta _VH\\\Delta H=175g*5.19\frac{J}{g*K}*(375.65K-301.15K)+175g*2.26\frac{kJ}{g} *\frac{1000J}{1kJ} \\\Delta H=4.63x10^{5}J=463kJ](https://tex.z-dn.net/?f=%5CDelta%20H%3D%5CDelta%20H_1%2B%5CDelta%20H_2%5C%5C%5CDelta%20H%3DmCp%5CDelta%20T%2Bm%5CDelta%20_VH%5C%5C%5CDelta%20H%3D175g%2A5.19%5Cfrac%7BJ%7D%7Bg%2AK%7D%2A%28375.65K-301.15K%29%2B175g%2A2.26%5Cfrac%7BkJ%7D%7Bg%7D%20%2A%5Cfrac%7B1000J%7D%7B1kJ%7D%20%5C%5C%5CDelta%20H%3D4.63x10%5E%7B5%7DJ%3D463kJ)

Answer Chemical reaction quantitatively depend on the reactant and product molecule
Answer: 1.31 × 10^47 sorry if its not the answer
Explanation:
1. a. FeS + 2HCl --> FeCl2 + H2S
b. This is a double- replacement reaction. (The elements "switch partners".)
2. a.2Na + F2 --> 2NaF
b. This is a composition/synthesis reaction. (The two reactants are combining or synthesizing to make one product.)
3. a. 2HgO --> 2Hg + O2
b. This is a decomposition reaction. (The single reactant is breaking down or "decomposing" into multiple reactants.)
4. Hydrogen gas reacts with oxygen gas to create water in a composition/synthesis reaction.
I hope these answers will help you! If you need any explanation, ask and hopefully I can get back to you. ;)
Eight because an octet has 8 electrons and when it’s full it’s stable. If it’s not full, it’s constantly sharing or borrowing electrons.
