Answer 1

$\huge\bold{\mathtt{\purple❥{A{\pink{N{\green{S{\blue{W{\red{E{\orange{R}}}}}}}}}}}}}$

Most alkali metal peroxides can be synthesized directly by oxygenation of the elements. Lithium peroxide is formed upon treating lithium hydroxide with hydrogen peroxide: 2 LiOH + H2O2 → Li2O2 + 2 H2O. Barium peroxide is prepared by oxygenation of barium oxide at elevated temperature and pressure.
