Write the net ionic equation for this reaction 4. Por each of the formalas givem below, give the total number of valence electrons for the molecle and draw the Lewis structure Formula # Valence Electrons Lewis structure a. O b. HBr c. CBr 5. Determine the H of reaction for this balanced equation using the data of All of formations. 6. You have a 25.00 grams sample of water at 0.0°C. How much heat would be required to warm this sample up to 50°C?

Explanation / Answer

Ans 3

a) The balanced molecular reaction is given as :

2AgNO3 (aq) + Na2CO3 (aq) = Ag2CO3 (s) + 2NaNO3 (aq)

b) The ionic equation is given as :

2Ag+ (aq) + 2NO3- (aq) + 2Na+ (aq) + CO32- (aq) = Ag2CO3 (s) + 2Na+ (aq) + 2NO3- (aq)

Cancelling out the spectator ions from both the side of equation , we get the net ionic equation as :

2Ag+ (aq) + CO32- (aq) = Ag2CO3 (s)
