Make an equation in three types propionic acid 1) calcium 2) barium oxide 3) barium hydroxide

1) Reaction of propionic acid with calcium (hydrogen H2 will evaporate, so in the reaction you need to put an up arrow next to it):
2CH3CH2COOH + Ca → (CH3CH2COO) 2Ca + H2
2) Reaction of propionic acid with barium oxide
2CH3CH2COOH + BaO → (CH3CH2COO) 2Ba + H2O
3) Reaction of propionic acid with barium hydroxide:
2CH3CH2COOH + Ba (OH) 2 → (CH3CH2COO) 2Ba + 2H2O
All three reactions require normal conditions (at a pressure of 760 mm Hg and a temperature of 0 ° C).
