A mixture of 0.10 molmol of NONO, 0.050 molmol of H2H2, and 0.10 molmol of H2OH2O is placed in a 1.0-LL vessel at 300 KK. The following equilibrium is established:

2NO(g)+2H2(g)←→N2(g)+2H2O(g)2NO(g)+ 2H2(g)←→N2(g)+2H2O(g)
At equilibrium [NO]=0.062M[NO]=0.062M.

Part A
Calculate the equilibrium concentration of H2
Part B
Calculate the equilibrium concentration of N2N2.
Part C
Calculate the equilibrium concentration of H2OH2O.
Part D
Calculate KcKc.

specific gravity is the density of a substance divided by the density of water. since (at standard temperature and pressure) water has a density of 1 gram/cm3, and since all of the units cancel, specific gravity is usually very close to the same value as density

so "c" is the answer

the role of the microscope world in creating new materials .

- lead + phosphoric acid = hydrogen + lead(ii) phosphate

"hydrogen bonding is the attraction of h atoms in the water molecule (slight + charge) to o atoms in a neighboring water molecule (slight - charge); it is a weak interatomic force. but it is still strong enough to the water molecules "stick" together."
