A structural formula for an organic compound that depicts each valence bond as a short line especially : the hexagonal ring formula for benzene
Answer:
Ca generally loses two electrons from its outer shell to form a Ca2+ ion.
Answer:
A small positively charged nucleus surrounded by revolving negatively charged electrons in fixed orbits
Answer:
.
Explanation
In HX , X is more electronegative than Y so HX will ionise more because of ionic bond between H and X . On the other hand H₂Y will be less polar as compared to HX so it will ionise to a lesser extent . Hence Ka will be more for HX . Ka represents the degree of ionisation of acid . Higher the ionisation , higher is the value of Ka . H₂Y which is less polar will ionise less and hence it will have lesser value of Ka .
Hence H₂Y will have value of 10⁻⁷ and HX will have value of ka equal to 10⁹ .
Limiting reactant in this experiment would be Magnesium since it will run out first
