@Abmon98 can you help?

abmon98 · Answer

sure but what do you think is right and why share us your thoughts

rhondasommer · Answer

I think it's true because compounds to be a compound has to have the same elements in the same proportion.

rhondasommer · Answer

right?

photon336 · Answer

let's put in an example say of we have water $$H_{2}O$$  and H2O2 are these compounds the same or different and how do you know?

rhondasommer · Answer

omg i feel so stupid lol

photon336 · Answer

but you see how a small difference in the number of atoms changes the properties in the compound?

rhondasommer · Answer

yeahhh

rhondasommer · Answer

waittt is water a pure substance?

photon336 · Answer

that's why it's important the same compound will always have the same elements in the same proportions.

photon336 · Answer

well @RhondaSommer if you just had a solution with only water in it it would be a pure substance

rhondasommer · Answer

it is
im pretty sure

rhondasommer · Answer

thanks

photon336 · Answer

if you had like water and sand then it would be a mixture no longer a pure substance
