you take 15 and divide it by 9.82 (gravity ) and then you have your time which is 1.5
Properties of ionic compounds<span>. High melting and boiling points - </span>Ionic<span> bonds are very strong - a lot of energy is needed to break them. ... Conductive when liquid - </span>Ions<span>are charged particles, but </span>ionic compounds<span> can only conduct electricity if their </span>ions<span>are free to move.</span>
