Pb(NO2)2 (aq) + 2 Kl (aq) – Pbl, (s) + 2 KNO (aq) In a lead iodide reaction, you begin with 125 g of
Pb(NO,) and 25 g of Kl. When the reaction is
completed, you measure 50 g of Pbly. How many
grams of KNO were created?

Infants born with severe respiratory problems are sometimes given liquid ventilation: they breathe a liquid that can dissolve more oxygen than air can hold. one of these liquids is a fluorinated compound, cf3(cf2)7br. the solubility of oxygen in this liquid is 66 mlo2 per 100 ml liquid. in contrast, air is 21 % oxygen by volume. calculate the moles of o2 present in an infant's lungs (volume: 12 ml ) if the infant takes a full breath of air. assume a pressure of 1 atm in the lungs.

Theoretically, which metal should be the most reactive? hydrogen lithium francium fluorine
