Answer: maybe 1.4 degrees higher than initial?
Not sure if all the needed info is here, I’m a bit rusty but I just tried to plug it into my calculator and got stuck. Anyway, the equation needed is Q=mcT, Q being energy, m mass, c spec. heat capacity and T as the change in temperature
Answer:1.

3.
4. 
5. 
Explanation:
Molecular formula is the chemical formula which depicts the actual number of atoms of each element present in the compound.
Empirical formula is the simplest chemical formula which depicts the whole number of atoms of each element present in the compound.
1.

5. 
has empirical formula of
A)
First ionization energy of Li:
Li(g) + 520 kJ/mol → Li⁺(g) + e⁻
B)
Electron affinity of Fluorine:
F(g) + e⁻ → F⁻(g) + 328 kJ/mol
For the compound formed to be neutral, the charge should be zero. This means that the positive charge should be equal to the negative charge. The balanced chemical reaction forming the neutral chromium oxide is shown below.
2Cr3+ + 3O2- ---> Cr2O3
Answer and Explanation:
<em>Metallic bonding occurs between two or the same metals. In a metallic bonding structure, there is an electrostatic attraction between the positive metal ions leaving a sea of delocalised electrons. The sea of delocalised electrons allows metals to conduct electricity because the delocalised electrons are free to carry charge around the structure.</em>
<em>Pure metals are soft because there are layers of metal ions free to slide over each other as they are in a regular arrangement, pattern and size. </em>
<em>Alloys can be harder than pure metals because the different sizes of the atoms disturb the layers, stopping them from sliding over each other. Alloying a pure metal can let the metal become stronger and less reactive.</em>
