The student investigated the effect of changing the temperature of the sodium thiosulfate
solution on the rate of reaction.
She plotted her results on a graph, as shown in Figure 2.
Describe the trends shown in the student's results. *

ca has a crystalline lattice with positive ions (since it is a metal, metals are positively charged) and electrons flow freely in its structure since the ca atoms have a large nuclear radius so the electrons are not tightly held, therefore the electrons can flow freely since they are not being highly attracted by the nucleus. moreover, one of the properties of metals are that they are conductors of electricity, thus proving ca is the element.
