Question

Why is the total mass always conserved in a chemical reaction? Be sure that your explanation includes the discussion of atoms and bonds.

Answer 1

there is no chemical reaction.... so what do i do !?(.-.;?

Answer 3

why does the british broadcasting channel have science on it .-.

Answer 4

In a chemical reaction, the electron lost by one atom is gained by another atom - that means the electron simply shifted from one atom to another. Like people shift their houses. So can we say that the electrons/atoms don't vanish in chemical reactions ?

Answer 5

Since electrons are just shifting places, no mass was lost. continue ur argument..

Answer 6

wait who shifts their houses? .-. how do you even do that?

Answer 7

Forget about that analogy, focus on electrons maybe :)

Answer 8

and what argument?...

Answer 9

You're trying to explain why mass is conversed in chemical reactions, right ?

Answer 10

yussss but you just said its not its just switching electrons

Answer 11

`conserved` means `doesn't change`

Answer 12

the total mass remains constant in a chemical reaction, so we say the total mass is conserved.

Answer 13

the total mass of products at the end of the reaction is equal to the total mass of the reactants at the beginning. this is because of the fact that the atoms will give their electrons to other atoms. that means that the electron only switches places and isnt destroyed.

Answer 14

so that :D

Answer 15

Looks perfect ! :)

Answer 16

wait but how do i talk about bonds in it too?

Answer 17

its pouring outside my house right now yet its still sunny -.- welcome to florida

Answer 18

maybe start something like below :
In a chemical reaction, while bonding the electrons lost by one atom are gained by other atoms...

Answer 19

wow! i heard florida is the state with most extreme climate conditions and most beaches xD

Answer 20

oh der so i already mentioned atoms /).(\ and what about bonds? i get that thats why the atoms loose the electrons cuz it forms a bond with another electron but what do i say .-.

Answer 21

yes.... that would indeed be florida XD it can be sunny around 97degrees one minute and the next thing you know its pouring .-. its crazy.... and yeah were a peninsula so we tend to have alot of beaches XD

Answer 22

do i just put... the lost of an electron from one atom in turn forms a bond with another electron?

Answer 23

In a chemical reaction, while bonding, the electrons lost by one atom are gained by other atoms...

Answer 24

^^

Answer 25

see that dosent sound anything like me XD "in a reaction, the electrons lost by one atom then forms a bond to another atom

Answer 26

chemical bond is NOT between electron and atom

Answer 27

chemical bond is between atom and atom

Answer 28

electrons are the mediators

Answer 29

.-. well then where are the electrons going?

Answer 30

or the glue that stick the atoms together

Answer 31

but i only need 8 electrons on the valance ring so cant they just form a bond with eachother .-.

Answer 32

chemical bond is between two atoms.

Answer 33

then what a bond between two electrons?

Answer 34

you need more than one atom to form a bond - one atom will not do

Answer 35

electrons repel eachother, there cannot be any bond between electrons

Answer 36

o.o i really hate chemistry.... how do they act like glue when all they do is repel?
