The Rusty Nails by Brad Liapis https://padlet.com/bliapis1/205cso76kt2u What do you predict will happen to the mass of the nails? A - The mass of the dry , rusted nails will be more than the mass of the dry nails before they rusted. B - The mass of the dry, rusted nails will be less than the mass of the dry nails before they rusted. C - The mass of the dry, rusted nails will be the same as the mass of the dry nails before they rusted. en-us 2019-03-19 15:26:40 UTC 2019-12-04 17:25:48 UTC hello@padlet.com 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. https://padlet.com/bliapis1/205cso76kt2u/wish/343086049 2019-03-19 20:52:59 UTC https://padlet.com/bliapis1/205cso76kt2u/wish/343086049 c https://padlet.com/bliapis1/205cso76kt2u/wish/343086069 it will weigh the same because it is a chemical reaction. And in a chemical reaction there is the conservation of mass.]]> 2019-03-19 20:53:04 UTC https://padlet.com/bliapis1/205cso76kt2u/wish/343086069 A https://padlet.com/bliapis1/205cso76kt2u/wish/343086100 the rust will add more weight to it ]]> 2019-03-19 20:53:10 UTC https://padlet.com/bliapis1/205cso76kt2u/wish/343086100 C https://padlet.com/bliapis1/205cso76kt2u/wish/343086156 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]]> 2019-03-19 20:53:24 UTC https://padlet.com/bliapis1/205cso76kt2u/wish/343086156 (stay the same) https://padlet.com/bliapis1/205cso76kt2u/wish/343086158 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 ]]> 2019-03-19 20:53:25 UTC https://padlet.com/bliapis1/205cso76kt2u/wish/343086158 A because there is no cover and stuff can get in. The rust will make it heavier https://padlet.com/bliapis1/205cso76kt2u/wish/343086171 2019-03-19 20:53:28 UTC https://padlet.com/bliapis1/205cso76kt2u/wish/343086171 (c) https://padlet.com/bliapis1/205cso76kt2u/wish/343086253 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.
