Question

Help please! How do you balance this?
_Fr2O + _H2O = ________

Answer 1

What do you think the products are?

Answer 2

Fr, O and H ?

Answer 3

A compound forms.

Answer 4

How?

Answer 5

Well this is a form of double displacement rxn.

Answer 6

According to my paper its still a synthesis reaction :(

Answer 7

Aren't synthesis rxn the adding of reactants to make a larger product?

Answer 8

Its to make one compound, yes

Answer 9

Decomposition rxn would be broken down, that is why Fr, O and H as individual atoms arn't formed.

Answer 10

What is formed is Fr(OH).

Answer 11

All you need to do is balance the equation. That['s why it's a synthesis rxn both reactants are combined to make a larger product.

Answer 12

Can you balance it up now?

Answer 13

How did you get Fr(OH)??

Answer 14

The individual OH ions in water attract to the Fr+ ion. Also the H+ ions in water form a hydroxide ion from the O in Fr2O.

Answer 15

Do you get it?

Answer 16

The H+ ions attract to oxygen, creating a -1 charge also, combined with the other hydroxide, another -1, so a total -2 charge, in comparison to Fr+.

Answer 17

@peekaboopork?

Answer 18

I think I do.... :(

Answer 19

Do you want me to explain it simpler?

Answer 20

Yes please! :( Im so sorry

Answer 21

No problem. Water is HOH- you know how it is composed of an OH- and H+ ion due to slight charges?

Answer 22

Yes

Answer 23

Okay. the OH- and H+ ions are released now.

Answer 24

The H+ ion will react to the Fr2O after it breaks up dissociates.

Answer 25

It becomes 2Fr(+) and O(2-). The H+ reacts with the O2- to make a OH- ion. See the charges 2-of the oxygen and +1 of the hydrogen? Add them up it will become -1 the charge of the hydroxide ion.

Answer 26

Makes sense?

Answer 27

Both of those hydroxides 2(OH-) now are attracted to the Fr+ ion.

Answer 28

OHHHHHH yes! I get it now!!!!
