Answer from: Luena

the resulting compound is Li+ Cl- in a crystalline lattice structure.

so first choice is wrong as its not a double bond

third choice is wrong as its not a ball-and-stick

fourth choick is also wrong as its not a triple bond

correct ans is The chemical compound will have a network structure.

Answer from: iamasia06

The chemical compound will have a network structure.

Explanation:

Li loses one electron to form Li⁺ cation and Cl gains one electron to form Cl⁻ anion. Li⁺ and Cl⁻ experience an electrostatic force of attraction forming an ionic bond. LiCl forms a 3D array of alternating Li⁺ cation and Cl⁻ anion such that the opposite charges balance each other.

LiCl exists in a crystalline lattice, where each Li⁺ has a coordination number of 6, or Li⁺ is surrounded by 6 Cl⁻ ions. The lattice of LiCl is called face centered cubic.

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.
