At the temperature of 1450 °c the equilibrium constant of the reaction n2(g) + o2(g) = 2no(g) is kc= 0,0900
calculate the molar concentrations to the equilibrium knowing that the initial mixture contains 1.00 mol of n2 and 1.00 mol of o2 in a volume of 5.00 l.

solutions: (0,142 mol/l; 0,142 mol/l; 0,116 mol/l)

hope this

explanation:

covalent bonds

consist of pairs of electrons shared by two atoms, and bind the atoms to fixed orientation and requre high energies to break them

ionic bonds

when two atoms differ considerably in their electronegativity, then one of the atoms will lose its electron to the other atom. this results in a positively charged ion(cation) and a negatively charged ion (anion)

the answer would be b i believe

i think it's letter a.
