On left, C l with 2 black dots each above, left, and below and 1 black dot right. On the right, C l with 2 black dots each above, right, and below and 1 black dot left. Chlorine, which is used to clean swimming pools, exists as two chlorine atoms covalently bonded to each other.

How many valence electrons does one chlorine (Cl) atom have?

Chlorine has seven valence electrons

Explanation:

The dot structure of chlorine was just described in the question. The two dots above, below and by the left are three lone pairs making a total of six electrons. There is another one black dot indicating one electron.

This one electron on both chlorine atoms combine to form the chlorine molecule Cl2.

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.
