How much heat is absorbed/released when 20.00 g of NH3(g) reacts in the presence of excess O2 (g) to produce NO (g) and H2O (l)
according to the following chemical equation?4NH3 (g) + 5O2 (g) ---> 4NO (g) +6H2O (l) Δ H: +1168 kJa. 342.9 kJ of heat are absorbed.b. 342.9 kJ of heat are released.c. 1372 kJ of heat are absorbed.d. 1372 kJ of heat are released.
Get the molarity we need to divide the number of moles of NaCl by the volume of the solution. So, 0.32 moles NaCl divided by 3.4 L, and that gives 0.094 M NaCl.
The ref blood cells are shaped like sickles or crescent moons, sticky cells can get stuck in small blood vessels which can slow or block blood flow and oxygen to parts of the body
