9 Laboratory Report Mole Ratios Mass of silver nitrate Mass of copper wire (initial) 33 1114 copper and silver nitrate atan a Mass of filter paper (step 10) Mass of leftover copper wire Appearance of leftover copper wire Mass of filter paper plus silver step 21) | I. Calculate the mass and moles of copper wire th reacted in this esperiment. 2. Calculate the mass and molessofsilver metal produced in the reaction. 3. Determine the mole ratio-the ratio of the number of moles of silver to the number of moles of copper Note: Round the result to the nearest whole number. 4. Use the silvercopper mole ratio to write the balanced chemical equation for the reaction of copper and silver nitrate. hole  147 1d Biological Chemistry 001. 14+(1 Laboratory Experimenfor General, Organic

Explanation / Answer

5. The factor to don´t have a big yield might be:

Nature of the reactants: some reactions are slower or faster than others, this might be because the physical state of the reactants, in this case you have a solid, the particles may not move that fast.

Temperature: Some reactions need higher temperatures in order to get the minimal energy to start a reaction, if the temperature is not the right, the reaction will be too slow or it may never happen.

6. molecular weight silver nitrate (170 g/gmol)

moles = mass / molecular weight = 1.51 / 170 = 0.0088 moles of silver nitrate available

cupper molecular weight = 63.5 g/gmol

moles = 1.974 / 63.5 = 0.031 moles of cupper available

According to the stoichiometry you need 2 moles of silver nitrate for every mole of cupper, so you need:

2 * 0.031 = 0.062 moles of silver nitrate we need and we onlye have 0.0088 moles of silver nitrate

silver nitrate must be the limiting reactant according to the data provided
