Hi melting point
WebAug 15, 2024 · Melting and boiling points increase across the three metals because of the increasing strength of their metallic bonds. The number of electrons which each atom can contribute to the delocalized "sea of electrons" increases. The atoms also get smaller and have more protons as you go from sodium to magnesium to aluminum. Webfor the production of HI is the quantitative reaction of iodine with hydrazine. 2I2+ N2H4→ 4HI + N2 Hydrogen Bromideis very water soluble and aqueous HBr becomes saturated at around 69% by weight at room temperature. A constant boiling point mixture exists at about 47.6% and this boils at 124.3 °C. Boiling more dilute solutions will
