Answer:
![C_m=0.474\frac{J}{g\°C}](https://tex.z-dn.net/?f=C_m%3D0.474%5Cfrac%7BJ%7D%7Bg%5C%C2%B0C%7D)
Explanation:
Hello.
In this case, since this is a system in which the water is heated up and the metal is cooled down in a calorimeter which is not affected by the heat lose-gain process, we can infer that the heat lost by the metal is gained be water, it means that we can write:
![Q_m=-Q_w](https://tex.z-dn.net/?f=Q_m%3D-Q_w)
Thus, in terms of masses, specific heats and temperatures we can write:
![m_mC_m(T_{eq}-T_m)=-m_wC_w(T_{eq}-T_w)](https://tex.z-dn.net/?f=m_mC_m%28T_%7Beq%7D-T_m%29%3D-m_wC_w%28T_%7Beq%7D-T_w%29)
Whereas the equilibrium temperature is the given final temperature of 28.4 °C and we can compute the specific heat of the metal as shown below:
![C_m=\frac{-m_wC_w(T_{eq}-T_w)}{m_m(T_{eq}-T_m)}](https://tex.z-dn.net/?f=C_m%3D%5Cfrac%7B-m_wC_w%28T_%7Beq%7D-T_w%29%7D%7Bm_m%28T_%7Beq%7D-T_m%29%7D)
Plugging the values in and since the density of water is 1.00 g/mL so the mass is 80.0g, we obtain:
![C_m=\frac{-80.0g*4.184\frac{J}{g\°C} (28.4\°C-24.0\°C)}{44.0g(28.4\°C-99.0\°C)}\\\\C_m=0.474\frac{J}{g\°C}](https://tex.z-dn.net/?f=C_m%3D%5Cfrac%7B-80.0g%2A4.184%5Cfrac%7BJ%7D%7Bg%5C%C2%B0C%7D%20%2828.4%5C%C2%B0C-24.0%5C%C2%B0C%29%7D%7B44.0g%2828.4%5C%C2%B0C-99.0%5C%C2%B0C%29%7D%5C%5C%5C%5CC_m%3D0.474%5Cfrac%7BJ%7D%7Bg%5C%C2%B0C%7D)

Answer:
a big trend i see, is it's decreasing
Explanation:
Answer:
The force applied to the object is an external force, from outside the system. When it does positive work it increases the gravitational potential energy of the system. Because gravitational potential energy depends on relative position, we need a reference level at which to set the potential energy equal to 0.
Considering that copper occupies Group 11, the ionic compound with a transition metal in it is c. CuSO₄.
<h3>What is a transition metal?</h3>
A transition metal is any of the set of metallic elements occupying a central block (Groups 3–12) in the periodic table. The differential electron occupies a d subshell.
