Which part of the following descriptions of a compound or element refers to its physical properties and which to its chemical properties? a. calcium carbonate is a white solid with a density of 2.71 g/cm3. it reacts readily with an acid to produce gaseous carbon dioxide. b. gray powdered zinc metal reacts with purple iodine to give a white compound.

Explanation:

Physical property is defined as the property which can be measured and whose value describes the state of physical system.

For Example: State, density etc.

Physical properties enlisted in question of calcium carbonate are:

Chemical property is defined as the property of a substance which is observed during a reaction where the chemical composition identity of the substance gets changed.

Chemical properties enlisted in question of calcium carbonate are:

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current
