Match each statement about forces of attraction to the correct description. Covalent bonds are classified as Covalent bonds are classified as drop zone empty. Intermolecular forces Intermolecular forces drop zone empty. The physical state of a molecular substance at a particular temperature and pressure depends on the strength of its The physical state of a molecular substance at a particular temperature and pressure depends on the strength of its drop zone empty. A change in the physical state of a molecular substance does NOT involve the breaking of

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current

i think its 5049.

i hope this !

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
