Bonding and Compound Questions1.) Do all ionic compounds dissolve in water, Do all covalent compounds dissolve in water? answer should be 50 to 100 words.
2.) Do the physical properties of water change when a compound is dissolved in water? If so, which properties change and why?
3.) Do all chemical compounds undergo each type of chemical reaction,i.e. synthesis, decomposition, metathesis-precipitation, metathesis-neutralization, redox-single displacement, redox-combustion and can this information be useful to a criminal investigation?
