Nitric oxide (NO) reacts with oxygen gas to form nitrogen dioxide (NO2), a dark brown gas: 2NO(g) + O2(g) → 2NO2(g)

In one experiment, 0.863 mol of NO is mixed with 0.501 mol of O2. Determine which of the two reactants is the limiting reactant. Calculate also the number of moles of NO2 produced.

The answer to the question is d

c. electrical charges of ionic bonds.

i hoped this , can i get brainliest plzgod bless you

Ch4 and ph3 are both covalent since they are composed both of non-metals.    ch4 is non- polar because of  london forces and has a geometry of tetrahedral  ph3 , on the other hand, is umbrella shaped polar and has dipole-dipole intermolecular force (imf) . since ph3 is polar, it has a stronger imf   

Ibelieve its because the stove is a cleaner burning fuel
