How many milliliters of 0.100 m naoh(aq) would be needed to completely neutralize 50.0 milliliters of 0.300 m hcl(aq)?
(1) 16.7 ml (3) 150. ml
(2) 50.0 ml (4) 300. ml

The NaOH can react with HCl with the formula: NaOH + HCl = NaCl + H2O. So if you want to neutralize the solution, the molar number of NaOH and NCl need to be equal. So we need 0.3*50/0.1=150 milliliters.

Ibelieve it's celsius. hope this .

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
