3Ca(OH)₂ (aq) + 2H₃PO₄ (aq) -> Ca₃(PO₄)₂ (s) + 6H₂O (l)
Development of cancer drugs seems to be the only answer related to chemistry so i’d say go with that one
Answer:
0.21mol Ar (g)

please and and thanks
Increase: volume, pressure, kinetic energy, gas particle collisions
Stays the same: number of moles of gas
