Question

This is my first one
An example of a synthesis reaction is:::
(H2 +O2=H2O2, this is just a regular example of synth. reaction.)
Here are the choices.. Pretty much which corresponds to the above part.
AB>A+B
AX+B>A+BX
A+B>AB

Answer 1

im thinking the last one though cuz ya know a+b makes ab

@sammixboo And I'm done :) peace \ /

Answer 15

Its fine @jabez177 No need to tag everybody on here....

Answer 16

Sorry! Can't help you here

o_>

Answer 17

AB>A+B -Decomposition : breaking apart a compound down to elements

AX+B>A+BX - single replacement : replaces a metal with a metal, or hydrogen.

A+B>AB - combination, combines two elements to form a compound

Answer 18

\(H_2 =~\text{hydrogen} ~ , ~ O_2 = ~\text{oxygen}\) Combining them you get Hydrogen peroxide, \(H_2O_2\)

Answer 19

So what would you call a reaction in which you COMBINE two elements?

Answer 20

Oh you would be combining which would be synthesis.

Answer 21

Good job :)

Answer 22

Do you think you could help with one last question?

Answer 23

I can try.

Answer 24

What does the reactivity series tell about an ion?


Which ions can replace each other in reactions
The atomic number of an atom
How many donor electrons an ion has
The melting point of an ion

I am not sure.... Okay, to be more honest, I am completely lost.

Answer 25

hint: reactivity series is used in single displacement reactions

Answer 26

And that is replacing a metal with a metal.....
I am sorry, I am still confused...

Answer 27

Well, the reactivity series comes in place of single replacement reactions because it tells how much more likely an ion of an element is going to react with the ions of a another element that is reacting. The more more active metal will lose electrons more easily

For example: \(\sf Fe(s) +CuSO_4(aq) \rightarrow FeSO_4(aq) + Cu(s)\)

Answer 28

You see how elements that are more active are displacing the ones that are not active enough? According to the Reactivity list, \(\sf Fe\) is more reactive than \(\sf Cu\), so it displaces copper.

Answer 29

So it would be to the extent of what can displace what.

Answer 30

yeah pretty much.

Answer 31

Hm, OK, Thank you @Jhannybean I really appreciate your help, it means a lot. thank you!!!!!!!!

Answer 32

Is it more understandable? :\

Answer 33

Yes ma'am

Answer 34

Would you be okay if i copy what you gave me for my notes?

Answer 35

If it's for notes, albeit, I wouldnt know <.<

Answer 36

I don't want to be the reason for you getting in trouble :P

Answer 37

Haha, I am going to write out info you gave me lol, The only thing i have written down is a lot of scribbled out things, yikes!!

Answer 38

Lol alright, good luck!

Answer 39

BTW: I got a 100, thanks!!

Answer 40

YAY!!

Answer 41

Wait a minute. you were taking a test?

Answer 42

Haha No, I took a review after I had it cleared up a bit, after my first question, not the second. Two different things sorry.

Answer 43

Oh okay. Good :)

Answer 44

Yea, I just forgot to tell you, my mom reminded me I should say thanks for that

Answer 45

Lol thanks.
