The mass of the dry, rusted nails will be more than  the mass of the dry nails before they rusted.the same as the mass of each dry nail

# data[].attributes.body
oxygen and metal reacted to create a compound which makes the mas more.

# data[].attributes.body
The nail will have less mass because it is losing materials and creating a new substance.

# data[].attributes.body
A.) Because the rust is just mass added on to the original mass of the nail before it was rusted.

# data[].attributes.body
I think the answer will be C because according to the conservation of mass in a chemical reaction nothing can be broken down or added everything is just rearranged. This meas the molecules in the rust are just rearranged.

# data[].attributes.body
I think C because even though a chemical reaction is occuring, nothing is really happening. The nail is just becoming rusty, but no weight is being added on.

# data[].attributes.body
I think c because of the conservation of mass

# data[].attributes.headline
I feel like it will be c because of the conservation of mass and a chemical reaction

The nail reacted to the moisture in the air there for a chemical reaction

# data[].attributes.body
I think C because the mass did not change therefore it still has the same weight as before.

# data[].attributes.body
I think that it will be the same is because the conservation of matter makes it so a chemical reaction can not decrease increase or add any new things to it.

A because there is no cover and stuff can get in. The rust will make it heavier

A because there is no cover and stuff can get in. The rust will make it heavier

# data[].attributes.body
I think it would be way the same because a chemical reaction is happening but nothing will be adding or be taken away, even though it would be rusted

# data[].attributes.body
The answer is c because when the nails rust a chemical reaction happens. When a chemical reaction happens nothing is created or destroyed, so the weight will be the same

# data[].attributes.body
the rust will add more weight to it

# data[].attributes.headline
I think that it would weigh the same because no atoms leave or get added the atoms stay the same they just change faces.  The atoms and molecules just change position.

it will weigh the same because it is a chemical reaction. And in a chemical reaction there is the conservation of mass.
