Answer:
![T_{eq}=28.9\°C](https://tex.z-dn.net/?f=T_%7Beq%7D%3D28.9%5C%C2%B0C)
Explanation:
Hello!
In this case, since it is observed that hot cadmium is placed in cold water, we can infer that the heat released due to the cooling of cadmium is gained by the water and therefore we can write:
![Q_{Cd}+Q_{W}=0](https://tex.z-dn.net/?f=Q_%7BCd%7D%2BQ_%7BW%7D%3D0)
Thus, we insert mass, specific heat and temperatures to obtain:
![m_{Cd}C_{Cd}(T_{eq}-T_{Cd})+m_{W}C_{W}(T_{eq}-T_{W})=0](https://tex.z-dn.net/?f=m_%7BCd%7DC_%7BCd%7D%28T_%7Beq%7D-T_%7BCd%7D%29%2Bm_%7BW%7DC_%7BW%7D%28T_%7Beq%7D-T_%7BW%7D%29%3D0)
In such a way, since the specific heat of cadmium and water are respectively 0.232 and 4.184 J/(g °C), we can solve for the equilibrium temperature (the final one) as shown below:
![T_{eq}=\frac{m_{Cd}C_{Cd}T_{Cd}+m_{W}C_{W}T_{W}}{m_{Cd}C_{Cd}+m_{W}C_{W}}](https://tex.z-dn.net/?f=T_%7Beq%7D%3D%5Cfrac%7Bm_%7BCd%7DC_%7BCd%7DT_%7BCd%7D%2Bm_%7BW%7DC_%7BW%7DT_%7BW%7D%7D%7Bm_%7BCd%7DC_%7BCd%7D%2Bm_%7BW%7DC_%7BW%7D%7D)
Now, we plug in to obtain:
![T_{eq}=\frac{37.60g*0.232\frac{J}{g\°C}*100.00\°C+25.00g*4.184\frac{J}{g\°C}*23.0\°C}{37.60g*0.232\frac{J}{g\°C}+25.00g*4.184\frac{J}{g\°C}}\\\\T_{eq}=28.9\°C](https://tex.z-dn.net/?f=T_%7Beq%7D%3D%5Cfrac%7B37.60g%2A0.232%5Cfrac%7BJ%7D%7Bg%5C%C2%B0C%7D%2A100.00%5C%C2%B0C%2B25.00g%2A4.184%5Cfrac%7BJ%7D%7Bg%5C%C2%B0C%7D%2A23.0%5C%C2%B0C%7D%7B37.60g%2A0.232%5Cfrac%7BJ%7D%7Bg%5C%C2%B0C%7D%2B25.00g%2A4.184%5Cfrac%7BJ%7D%7Bg%5C%C2%B0C%7D%7D%5C%5C%5C%5CT_%7Beq%7D%3D28.9%5C%C2%B0C)
NOTE: since the density of water is 1g/cc, we infer that 25.00 cc equals 25.00 g.

<span> because gasoline changes volume as a function of temperature or because there are different grades of gasoline or because the values are given in different units of measure .</span>
Answer:
<h2>The answer is 35 mL</h2>
Explanation:
Density of a substance can be found by using the formula
![Density(\rho) = \frac{mass}{volume}](https://tex.z-dn.net/?f=Density%28%5Crho%29%20%3D%20%20%5Cfrac%7Bmass%7D%7Bvolume%7D%20)
From the question we are finding the amount of space the gas will occupy that's the volume of the gas
Making volume the subject we have
![volume = \frac{mass}{Density}](https://tex.z-dn.net/?f=volume%20%3D%20%20%5Cfrac%7Bmass%7D%7BDensity%7D%20)
From the question
mass = 23.8 g/mL
Density = 0.68 g/mL
Substitute the values into the above formula and solve
That's
![volume = \frac{23.8}{0.68}](https://tex.z-dn.net/?f=volume%20%3D%20%20%5Cfrac%7B23.8%7D%7B0.68%7D%20)
We have the final answer as
<h3>35 mL</h3>
Hope this helps you
Uranium, most uranium does derive from a star. However, not from our sun.
