An electrically neutral molecule has the formula c3h4o2n. if the carbon atoms form the usual number of bonds, how many covalent bonds will each hydrogen atom have with other atoms in the molecule? an electrically neutral molecule has the formula c3h4o2n. if the carbon atoms form the usual number of bonds, how many covalent bonds will each hydrogen atom have with other atoms in the molecule? 3 2 4 5 1

            One

Explanation:

                   Covalent bond or molecular bond is a type of chemical bond which is formed by the mutual sharing of valence electrons between two atoms. These valence electrons are often the unpaired electrons present in valence shell of an atom.

Examples:

Element         # of Electrons        Electronic Config.          # of Covalent Bonds

   H                           1                                1s¹                                           1

   C                           6             1s², 2s¹, 2px¹, 2py¹,2pz¹                           4

   N                           7             1s², 2s², 2px¹, 2py¹,2pz¹                           3

   O                           8             1s², 2s², 2px², 2py¹,2pz¹                          2

Result:

          As Hydrogen atom contains only one electron in its valence shell, therefore it will only make one single covalent bond with either Carbon, Nitrogen or Oxygen.

1.consider the following balanced equation and answer parts a through. show calculations for each part.  

3 ag(s) + 4 hno3(aq) → 3 agno3(aq) + no(g) + 2 h2o(l)  

a. calculate the number of moles of agno3 produced by the reaction of 3 moles of ag with excess hno3. if the number to the left of the compound represents the number of moles of the compound which are present, then 3 moles of ag react with 4 moles hno3 to produce 3 moles agno3 (aq).

so the answer to a would be 3 moles.

b. calculate the number of moles of agno3 produced by the reaction of 108 grams of ag with excess hno3.  

i'm not sure how to plug in the grams of silver into an equation using moles to find how many moles are produced.

c. calculate the number of grams of agno3 produced by the reaction of 108 grams of ag with excess hno3  

d. calculate the number of moles of no produced as a byproduct of the reaction of 108 grams of ag with excess hno3.  

e. calculate the number of grams of no produced as a byproduct starting with 108 grams of ag and excess hno3.

answer carbon and three oxygen atoms;
