In a Victor Meyer's experiment, 0.52 g of an organic liquid of molar mass 120 gmol" was
vapourized at a temperature of 298 K and
pressure of 1.013 x 105 Nm 2. Calculate the
volume (cm?) of air displaced. (Given that the
saturated vapour pressure of water at 298 K is
2.32 x 103 Nm).​

Why do sodium and neon have vastly different chemical and physical properties despite having similar atomic masses?

Balance and in which category does it fit in? single or double displacement or synthesis or decomposition? (a) k2 o → k + o2 (b) na + i2 → nai (c) cu(no3 )2 + naoh → cu(oh)2 + nano3 (d) kclo3 → kcl + o2 (e) ca(no3 )2 + hbr → cabr2 + hno3 (f) sn(oh)2 → sno + h2 o (g) p4 + n2 o → p4 o6 + n2 (h) fe + al2 (so4 )3 → feso4 + al (i) alcl3 + na2 co3 → al2 (co3 )3 + nacl (j) c3 h6 + o2 → co2 + h2 o

The element that has the greatest electronegativity is
