What is the mole ratio between NH3 and H2O in the following reaction: 4NH3(g)+ 6NO(g)>5N2(g) +6H2O(l)

1 mole of nitrogen (N2) reacts with 3 moles of hydrogen (H2) to form 2 moles of ammonia (NH3) ... 4 NH3 (g) + 5 O2 (g) --> 4 NO (g) + 6 H2O (g) ... Example: What is the molar ratio between Li and N2 in the following reaction

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

in scientific notation, the value of the  speed of light in a vacuum

  will be written as 2.995 * 10^8. when this value is represented in the form of

  a * 10^b, then, a = 2.995 and b = 8.

the value of the speed of light in a vacuum given above can also be rounded up to approximately 300000000. in this case, the scientific notation will be written as 3 *10^8.
