answer
When an electron temporarily occupies an energy state greater than its ground state, it is in an excited state. An electron can become excited if it is given extra energy, such as if it absorbs a photon, or packet of light, or collides with a nearby atom or particle
Answer:
N2(g) + 3H2(g) → 2NH3(g)
Explanation:
Balanced chemical equations only show formulae, not names. A balancing number, written in normal script, multiplies all the atoms in the substance next to it.
<span>20%. By forming an iceglaze over the surfaces, freezing precipitation accounts for 20% of all winter weather related injuries in the United States. When the freezing precipitation leads to accumulation of 0.25 inch ice, it is known as Ice storm.</span>
I'll tell you how to solve it-
<span>all the C ends up as CO2 </span>
<span>mg of C = (12.011/44.011) x 33.5 mg CO2 = 9.142 mg C </span>
<span>all of the H ends up as H2) </span>
<span>mg H = (2.016/18.016) x 41.1 mg H2O = 4.599 mg H </span>
<span>mg N = 35.0 - 9.14 - 4.60 = 21.26 </span>
<span>CxHyNz represents the empirical formula </span>
<span>where x = moles of C atoms, y = moles of H atoms, and z = moles of N atoms in (1 mole of) the molecule </span>
<span>Calculate the moles of C, H, and N that you found. </span>
<span>Determine the ratio of the moles x : y : z </span>
<span>Do that and then look at my calculations- </span>
<span>9.14 mg C / 12.011 mg/mmol = 0.76 millimol C </span>
<span>4.60 mg H / 1.008 mg/mmol = 4.60 millinol H </span>
<span>21.26 mg N / 14.006 mg/mmol = 1.52 millimol N </span>
<span>divide by the smallest number (0.76) </span>
<span>C = 1 </span>
<span>H = 6 </span>
<span>N = 2</span>
