CH4(g) + F2(g) > CH3F(g) + HF(g) Count chemical bonds and
calculate bond breaking and
bond making energy. Is it exo- or
endothermic reaction?

93.2 ml + 3920 ml = 4013 ml total  

(93.2 ml) * (2.03 m) / (4013 ml) = 0.0471 m

the volume in in l of the diluted solution would be 0.0471 m.

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z

answer

it forms an anion that has a larger radius. anions have a negative charge and are larger than the original atom.
