1) A mixture of 25.0 g of NO and an excess of O2 reacts according to the balanced equation
___NO(g) + ___O2(g) ® ___NO2(g)
How many liters of NO2, at STP, are produced?
2) Ammonium nitrate, NH4NO3, can decompose explosively when heated to a high temperature according to the equation
___NH4NO3(s) ® ___N2(g) + ___H2O(g) + ___O2(g)
If 100.0 g of ammonium nitrate decomposes at 450 oC, how many liters of gaseous products would be formed? (Assume atmospheric pressure is 1.00 atm)
Lindane, a powerful insecticide, is a member of this group. The molar mass of lindane is 290.8. How many atoms of carbon does a molecule of lindane contain
HF is a stronger acid than HBR because F has greater electronegativity than Br 2) the acid (HA) strength will increase when the H-A bond strength increases
Hydrogen and iodine gases react to form hydrogen iodide gas. H2(g) + I2(g) → 2 HI(g) At a certain temperature and pressure 0.70 L of H2 reacts with 0.70 L of I2.
