Answer: physical change.

Explanation:

A chemical change is defined as a change in which a change in chemical composition takes place. A new substance is formed in these reactions.  Example: Corrosion of iron.  

Chemical property is defined as the property of a substance which becomes evident during chemical changes. Example: Reactivity with other substances

A physical change is defined as a change in which there is alteration in shape, size etc. No new substance gets formed in these reactions.  Example: evaporation of water

Physical property is defined as the property of a substance which becomes evident during physical changes. Example: Boiling point

Thus Water evaporating from a puddle is an example of a physical change.

It is an example of physical change. The molecules are not changing, so it is not chemical, and a physical property is something that a physical thing has.

How many grams of Fe2+ are there in 0.003109 moles of Fe2+?
Sergio [31]

Answer: 0.174 g

Explanation:

First of all understand that charge on an atom like here 2+ will not vary molar mass. because ions are formed by loss or gain of electrons and electrons do not contribute to the mass of an atom or ion. so losing or gaining electron doesnt create any difference.

molar mass of Fe, i.e. mass of 1 mole of Fe is 56 g. So, mass of 1 mole of Fe2+ will also be 56 g.

given is 0.003109 moles of Fe2+,

Use maths,

1 mole of Fe2+ weighs 56 g

So, 0.003109 moles will weigh = (56 g / 1 mol ) x 0.003109 = 0.174 g.
