What is break-junction technique for molecular electronics? briefly explain the procedures of the technique. how can we control the electrode gap in it? can we use steel as substrate for it? why? when we measure the conductance of benzene-1,4- dithiolate molecule using break-junction technique, how can we judge the point when a single molecule is connecting two gold electrodes

answer and explanation;

composition refers to both the types of minerals within a rock and the overall chemical makeup of the rock while texture refers to the size and arrangement of the minerals or grains that make up a rock. both composition and texture can be used to classify rocks, such as igneous rocks. texture describes how the rock became solid or crystallized from liquid, melted rock. composition of a rock describes the minerals that make up a particular rock.
