Solve the following problems Phosphorous reacts with bromine to form phosphorous tribromide. If 35.0 grams of bromine are reacted and 27.9 grams of phosphorous tribromide are formed, what is the percent yield? (Molar Masses: Br = 79.90 g/mol and PBr = 270. 69 g/mol 2 P + 3 Br2 ____> 2 PBr3
Solve the following problems
- Phosphorous reacts with bromine to form phosphorous tribromide. If 35.0 grams of bromine
are reacted and 27.9 grams of phosphorous tribromide are formed, what is the percent yield? (Molar Masses: Br = 79.90 g/mol and PBr = 270. 69 g/mol
2 P + 3 Br2 ____> 2 PBr3
2. Silver Nitrate reacts with Magnesium Chloride to produce Silver Chloride and Magnesium Nitrate. If 305 grams of silver nitrate are reacted in an excess of magnesium chloride producing 23.7 grams of magnesium nitrate, what is the percent yield? (Molar Masses: AgNO3 = 169.87 g/mol and Mg(NO3)2 = 148.30 g/mol)
2 AgNO3 + MgCl2 ________> 2 AgCl + Mg(NO3)2
3. If 7.3 grams of sodium carbonate are used in the reaction and the result a 74.0% yield, what is the actual yield(grams )of sodium phosphate will be formed? (Molar masses: Na2CO3 = 105.99 g/mol and Na3PO4 = 163.94 g/mol
Sn3(PO4)4 + 6 Na2CO3 → 3 Sn(CO3)2 + 4 Na3PO4
