In accordance with the balanced chemical reaction, volume in L = 0.25 L of a 0.209m ki solution is required to upon and with 2.43 g of cu(no3)2.
Chemical processes occur when atoms form or break chemical bonds. The molecules that start a chemical reaction are known as reactants, and the substances that are produced of the reaction are known as products.
Chemical changes create the preponderance of our power generation. Chemical reactions are used to test, identify, and evaluate a wide variety of materials. Examples include pool lab tests and forensic testing from series like "CSI."
Mass of Cu(NO₃)₂ = 2.43 g
Volume of KI = ?
Balanced chemical equation:
4KI + 2Cu(NO3)2 = 2CuI + I2 + 4KNO3
Moles of Cu(NO₃)₂:
Mass x molar mass Equals number of moles
2.43 g/187.56 g/mol is the number of moles.
Number of moles = 0.013 mol
Cu(NO₃)₂ : KI
2 : 4
0.013 : 4 × 0.013=0.052 mol
Volume of KI:
amount in L = solute moles/molarity
volume in mol/mol/L = 0.052 mol/mol/L
volume in L = 0.25 L
