Explanation & Answer

Hey there! Here are the answers. Let me know if you have any questions. I'm attaching a DOCX file and a PDF file.

1) Silver nitrate reacts with barium chloride produces silver chloride and barium nitrate
a) Write the following equation in formula form
𝐴𝑔𝑁𝑂3 (𝑎𝑞) + 𝐵𝑎𝐶𝑙2 (𝑎𝑞) → 𝐴𝑔𝐶𝑙(𝑠) + 𝐵𝑎(𝑁𝑂3 )2 (𝑎𝑞)
b) Balance the equation
2𝐴𝑔𝑁𝑂3 (𝑎𝑞) + 𝐵𝑎𝐶𝑙2 (𝑎𝑞) → 2𝐴𝑔𝐶𝑙(𝑠) + 𝐵𝑎(𝑁𝑂3 )2(𝑎𝑞)
c) Calculate the number of grams of silver chloride produced from 16.4g of silver nitrate
𝑔 𝐴𝑔𝐶𝑙 = 16.4 𝑔 𝐴𝑔𝑁𝑂3 (

1 𝑚𝑜𝑙 𝐴𝑔𝑁𝑂3
2 𝑚𝑜𝑙 𝐴𝑔𝐶𝑙
143.32 𝑔 𝐴𝑔𝐶𝑙
)(
)(
)
169.87 𝑔 𝐴𝑔𝑁𝑂3 2 𝑚𝑜𝑙 𝐴𝑔𝑁𝑂3
1 𝑚𝑜𝑙 𝐴𝑔𝐶𝑙
𝑔 𝐴𝑔𝐶𝑙 = 13.8 𝑔 𝐴𝑔𝐶𝑙

d) How many grams of barium chloride are needed to produce 89.0g of barium nitrate?
𝑔 𝐵𝑎𝐶𝑙2 = 89.0 𝑔 𝐵𝑎(𝑁𝑂3 )2 (

1 𝑚𝑜𝑙 𝐵𝑎(𝑁𝑂3 )2
1 𝑚𝑜𝑙 𝐵𝑎𝐶𝑙2
208.23 𝑔 𝐵𝑎𝐶𝑙2
)(
)(
)
261.34 𝑔 𝐵𝑎(𝑁𝑂3 )2 1 𝑚𝑜𝑙 𝐵𝑎(𝑁𝑂3 )2
