Chemical Reactions by Brookelynn Will https://padlet.com/23willb/mjzr8v6yofoc Brookelynn Will and Morgan Furstenberg en-us 2017-11-03 13:28:14 UTC 2017-11-29 14:56:22 UTC hello@padlet.com How can changes in matter be described? (DAY 1) 23willb https://padlet.com/23willb/mjzr8v6yofoc/wish/204857188 It can be described in two ways! Chemical properties and Physical properties. So like if you where to burn an egg or if metal on your bike is rusting away, that would be an example of a chemical property. A physical property is when the color, shape, mass, or length changes. When you crack an egg or tear a piece of paper, that is an physical change.]]> 2017-11-08 15:19:27 UTC https://padlet.com/23willb/mjzr8v6yofoc/wish/204857188 How can you tell when a chemical reaction occurs?(Day 2) 23willb https://padlet.com/23willb/mjzr8v6yofoc/wish/205714012 It can be a few things! It can be the difference of the color. It can be when heat, light, or sound is given off/ absorbed. Last but not least it can be a solid material forms into a liquid! These are examples for when chemical reactions occurs.]]> 2017-11-10 15:03:35 UTC https://padlet.com/23willb/mjzr8v6yofoc/wish/205714012 What are the differences between endothermic and exothermic?(Day3) 23willb https://padlet.com/23willb/mjzr8v6yofoc/wish/205717343 Exothermic release coldness. For example burning and freezing. Like a candle burning or an ice cube freezing. While exothermic releases coldness, endothermic release warmth. For example melting and boiling. Like grilling up some hamburgers or an ice-cube melting.

( Day 5) 23willb https://padlet.com/23willb/mjzr8v6yofoc/wish/206275479 The law of conservation of mass is a law of science that states they energy cant be destroy nor created. Energy can only change form or transfer to object to object. ]]> 2017-11-13 15:09:02 UTC https://padlet.com/23willb/mjzr8v6yofoc/wish/206275479 Sources 23willb https://padlet.com/23willb/mjzr8v6yofoc/wish/206760200 1.

It also shows you the physical state of a substance, and whether it's  a solid, liquid,  or gas.

Examples?(Day 6) 23willb https://padlet.com/23willb/mjzr8v6yofoc/wish/208745472 The chemical equation needs to be balanced to be able to follow the law of conversation. When the number of atoms are equal on both sides it is a balanced chemical equation.

(Day 7 23willb https://padlet.com/23willb/mjzr8v6yofoc/wish/208934958 The first chemical reaction is the combination Reaction. The second chemical reaction is the single- replacement reaction. The third and fourth one is Double replacement reaction and the decomposition reaction. Those are some of the type of chemical reactions but there is six! Chemist has classified these  reaction into groups because it was easier for them to figure them out.]]> 2017-11-21 01:23:20 UTC https://padlet.com/23willb/mjzr8v6yofoc/wish/208934958
