a covalent bond and an ionic bond. An ionic bond if formed from the transfer of electrons from the outer shell of atoms. ... An example of this is NaCl, where the sodium atom becomes Na+ due to the loss of electrons, and the chlorine atom becomes the negatively charged chloride (Cl-).
Well, you would need to know how to properly name these chemical compounds and elemental compounds, specifically ionic compounds.
1. H2 + I2 -> 2HI - Synthesis
2. 2Li + 2HCl -> 2LiCl + H2 - SR - Single replacement
3. Na2CO3 -> Na2O + CO2 - Decomposition
4. 2HgO -> 2Hg + O2 - Decomposition
5. Mg(OH)2 -> MgO + H2O - Decomposition
6. Cu + Cl2 -> CuCl2 - Synthesis
7. Ca(ClO3)2 -> CaCl2 + 3O2 - Decomposition.
8. 2Li + 2H2O -> 2LiOH + H2 - Single Replacement Reaction.
Energy required to vaporize : 32.3 kJ
<h3>Further explanation
</h3>
The heat to change the phase can be formulated :
Q = mLf (melting/freezing)
Q = mLv (vaporization/condensation)
Lf=latent heat of fusion
Lv=latent heat of vaporization
Mass of water = 14.27 g
Latent heat of vaporization
( boiling point of 100 ºC) : 2260 J/g
Energy required :
Answer:
Option B . heat is taken in
