This problem is providing us with the mass (70 g), absorbed heat (96 J) and initial and final temperatures (293 K and 313 K, respectively) so the specific heat of the material is required and found to be 0.0686 J/(g*K) as shown below:
<h3>
Calorimetry:</h3>
In chemistry, we can go over calorimetry by writing the following relationship among heat, mass, specific heat and temperature change:
Thus, one can get the specific heat by solving for C in the previous equation:
Hence, we can plug in the given data to obtain:

Answer:
Mgf2 Bond type
Therefore, one Mg2+ needs two F– ions to balance. The 2+ of the Mg is balanced by having two -1 charged ions. Therefore, the formula of the compound is MgF2. The subscript two indicates that there are two fluorines that are ionically bonded to magnesium.

they are produced by the body in response to the presence of foreign substance
Answer:
Internal energy
Explanation:
Particles have two main energies that scientists acknowledge.
- The energy that is associated with their movement which we call kinetic energy. It is worth noting that particles have different kinetic energy, however the average kinetic energy that they have is directly proportional to temperature.
- The energy that is due to the interactive forces (attraction or repulsion) between particles is called potential energy
When these two types of energies are considered collectively, we call that internal energy
