Answer:
![C_{alloy}=0.497\frac{J}{g\°C}](https://tex.z-dn.net/?f=C_%7Balloy%7D%3D0.497%5Cfrac%7BJ%7D%7Bg%5C%C2%B0C%7D)
Explanation:
Hello there!
In this case, according to this calorimetry problem on equilibrium temperature, it is possible for us to infer that the heat released by the metal allow is absorbed by the water for us to write:
![Q_{allow}=-(Q_{water}+Q_{Al})](https://tex.z-dn.net/?f=Q_%7Ballow%7D%3D-%28Q_%7Bwater%7D%2BQ_%7BAl%7D%29)
Thus, by writing the aforementioned in terms of mass, specific heat and temperature, we have:
![m_{alloy}C_{alloy}(T_{eq}-T_{alloy})=-(m_{water}C_{water}(T_{eq}-T_{water})+m_{Al}C_{Al}(T_{eq}-T_{Al})](https://tex.z-dn.net/?f=m_%7Balloy%7DC_%7Balloy%7D%28T_%7Beq%7D-T_%7Balloy%7D%29%3D-%28m_%7Bwater%7DC_%7Bwater%7D%28T_%7Beq%7D-T_%7Bwater%7D%29%2Bm_%7BAl%7DC_%7BAl%7D%28T_%7Beq%7D-T_%7BAl%7D%29)
Then, we solve for specific heat of the metallic alloy to obtain:
![C_{alloy}=\frac{-(m_{water}C_{water}(T_{eq}-T_{water})+m_{Al}C_{Al}(T_{eq}-T_{Al})}{m_{alloy}(T_{eq}-T_{alloy})}](https://tex.z-dn.net/?f=C_%7Balloy%7D%3D%5Cfrac%7B-%28m_%7Bwater%7DC_%7Bwater%7D%28T_%7Beq%7D-T_%7Bwater%7D%29%2Bm_%7BAl%7DC_%7BAl%7D%28T_%7Beq%7D-T_%7BAl%7D%29%7D%7Bm_%7Balloy%7D%28T_%7Beq%7D-T_%7Balloy%7D%29%7D)
Thereby, we plug in the given data to obtain:
![C_{alloy}=\frac{-(400g*4.184\frac{J}{g\°C} (30.5\°C-10.0\°C)+200g*0.900\frac{J}{g\°C}(30.5\°C-10.0\°C)}{150g(30.5\°C-540\°C)} \\\\C_{alloy}=0.497\frac{J}{g\°C}](https://tex.z-dn.net/?f=C_%7Balloy%7D%3D%5Cfrac%7B-%28400g%2A4.184%5Cfrac%7BJ%7D%7Bg%5C%C2%B0C%7D%20%2830.5%5C%C2%B0C-10.0%5C%C2%B0C%29%2B200g%2A0.900%5Cfrac%7BJ%7D%7Bg%5C%C2%B0C%7D%2830.5%5C%C2%B0C-10.0%5C%C2%B0C%29%7D%7B150g%2830.5%5C%C2%B0C-540%5C%C2%B0C%29%7D%20%5C%5C%5C%5CC_%7Balloy%7D%3D0.497%5Cfrac%7BJ%7D%7Bg%5C%C2%B0C%7D)

Jill and Susan violated safety procedures by not properly listening and/or reading over the instructions to know all the materials, steps, and equipment they need for the lab. Hope this helps!
Answer:
An elementary particle that is identical with the nucleus of the hydrogen atom, that along with the neutron is a constituent of all other atomic nuclei, that carries a positive charge numerically equal to the charge of an electron.
Example:
The nucleus of a hydrogen atom or the H+ ion is an example of a proton. Regardless of the isotope, each atom of hydrogen has 1 proton; each helium atom contains 2 protons; each lithium atom contains 3 protons and so on.
Answer:
the second one seems right :)
