Consider the sodium borohydride reduction of camphor to isoborneol. A reaction was performed in which 1.600 g of camphor was red
ki77a [65]

Answer:

62.5%

Explanation:

Number of moles of camphor reacted= 1.6g/152.23 g/mol = 0.011 moles

Since the reaction is 1:1,  then 0.011 moles of isoborenol is also produced.

Theoretical yield of isoborenol produced = 154.25 g/mol * 0.011 moles = 1.698 g

% yield = actual yield/theoretical yield * 100

% yield =  1.062 g/1.698 g * 100

% yield =  62.5%

Which statement is true about crystal lattice energy
Arturiano [62]
Hey there!:

1) The additional stability that accompanies the formation of the network<span>Crystalline is measured as network enthalpy. 
</span>2) The reticular energy is the energy released when the solid Crystal isform from separate ions in the gaseous state. Always exothermic.<span>
3) </span>The enthalpy of the network depends directly on the size of the loads and conversely in the distance between the ions .
