BaCl2 + Na3PO4 -----> NaCl + Ba3(PO4)2.

If 0.5 moles of BaCl2 is mixed with 0.2 moles of Na3PO4, the maximum number of moles of Ba3(PO4)2 that can be formed is?

the USEPA assumes that each person breathes 20 cubic meters of air per day. If the air we breathe in has 50% relative humidity at 20 °C, and we breathe it out with 100% relative humidity at 37 °C, how many milliliters of water would we need to drink each day just to replace the water lost by breathing? The vapor pressure of water at 20 °C is 17.5 mmHg and at 37 °C it is 47.1 mmHg. Assume the volume of air
breathed in is the same as that breathed out.

10 g sample of CaCl2 and NaCl is treated to precipitate all the Calcium as CaCO3. This CaCO3 is heated to convert all the Ca into CaO and final mass of CaO is 1.62 g. The % by mass of CaCl2 in the original mixture is?

The black compound which on heating with concentrated Hydrochloric acid gives a greenish yellow gas
