The order of the elements and number of elements will often be different afterwards, though not gone because matter cannot be created or destroyed so the conservation of mass can help you make sure to have all of the elements accounted for and the chemical formulas written correctly. This also applies to everyday life, for instance, when you leave a cup of water out, over time some of the water will dissapear, the water doesn't just leave it simply is rearanged when it goes into the air. Instead of being the chemical formula of H₂O it becomes 2H₂O₂. It also applies to many other things.]]> 2017-03-22 18:54:45 UTC https://padlet.com/bgashcroft0429/classesofmatterscience/wish/161940555 jmbegay1127 https://padlet.com/bgashcroft0429/classesofmatterscience/wish/161940913 How do you balance a chemical equation?
Answer:
To balance out the equation, a number must be placed in front of the formula. Meaning you're adding energy to the existing equation.]]> 2017-03-22 18:55:54 UTC https://padlet.com/bgashcroft0429/classesofmatterscience/wish/161940913 bgashcroft0429 https://padlet.com/bgashcroft0429/classesofmatterscience/wish/162494354 https://www.youtube.com/watch?v=3lHHOiTdmK4]]> 2017-03-24 18:06:08 UTC https://padlet.com/bgashcroft0429/classesofmatterscience/wish/162494354 https://padlet.com/bgashcroft0429/classesofmatterscience/wish/162497105 A shorthand way to use chemical symbols and numbers to represent a substance.]]> 2017-03-24 18:16:11 UTC https://padlet.com/bgashcroft0429/classesofmatterscience/wish/162497105 https://padlet.com/bgashcroft0429/classesofmatterscience/wish/162500060 The basic building block of matter.]]> 2017-03-24 18:28:03 UTC https://padlet.com/bgashcroft0429/classesofmatterscience/wish/162500060 jmbegay1127 https://padlet.com/bgashcroft0429/classesofmatterscience/wish/162500222 The law that states that mass can not be created or destroyed during ordinary physical and chemical changes. ]]> 2017-03-24 18:28:34 UTC https://padlet.com/bgashcroft0429/classesofmatterscience/wish/162500222 jmbegay1127 https://padlet.com/bgashcroft0429/classesofmatterscience/wish/163600434 Why does the formula change?

Answer:
The chemical formula changes when an oxygen atom is created during the chemical reaction. During a chemical reaction, the atoms are moved around. To obey the law, the equation must be balanced.]]> 2017-03-30 05:28:21 UTC https://padlet.com/bgashcroft0429/classesofmatterscience/wish/163600434 jmbegay1127 https://padlet.com/bgashcroft0429/classesofmatterscience/wish/163623778 There's no new mass created when the light bulb.
