How many moles of ba3(po4)2 can be formed when 1.3 moles of baco3 react with 2.5 moles of fepo4?
3baco3 + 2fepo4 yields ba3 (po4)2+ fe2 (co3)3
2.6 mol ba3(po4)2
2.5 mol ba3(po4)2
1.3 mol ba3(po4)2
0.43 mol ba3(po4)2

3BaCO3 + 2FePO4 > Ba3(PO4)2+ Fe2(CO3)3
3 moles 1 mol

3 mol BaCO3 1 mol Ba3(PO4)2
1.3 mol BaCO3 X mol Ba3(PO4)2
X = (1.3×1)/3 = 0.43 mol

Evaporation: this is when warmth from the sun causes water from oceans, lakes, streams, ice and soils to rise into the air and turn into water vapour (gas). water vapour droplets join together to make clouds! condensation: this is when water vapour in the air cools down and turns back into liquid water.
