2019-5-26Multipod gold nanocrystals have been synthesied via a simple solution-phase chemical reduction method at room temperature. Two types of structurally different particles are observed including the regular tripod which lies on the substrate with its 111 plane and the cross-like tetrapod that sits on its 100 plane. Both structures have pods of 10 nm sies and grow along 110

B Because the coefficients of gold and the AuCN 2 ion are the same in the balanced chemical equation assuming that Zns is present in excess the number of moles of gold produced is the same as the number of moles of AuCN 2 i.e. 0.132 mol of Au. The problem asks for the mass of gold that can be obtained so the number of
