Aballoon, whose volume at 23°c is 535 ml, is heated to 46°c. assuming the pressure and amount of gas remain constant, what is the volume of the balloon at 46°c

Due to the ideal gas law, we have an equation: PV=nRT. So when the pressure and amount of gas are constant, V1/T1=V2/T2. Temperature using the unit of K. So the answer is 535*319/296=576.6 mL.

Ch4 and ph3 are both covalent since they are composed both of non-metals.    ch4 is non- polar because of  london forces and has a geometry of tetrahedral  ph3 , on the other hand, is umbrella shaped polar and has dipole-dipole intermolecular force (imf) . since ph3 is polar, it has a stronger imf   

Radioactive fallout is a result of the fission creation used to ignite the thermonuclear fusion reaction.
