Question

Can you please complete the reaction and balance 'em.
1. P_4 O_10+ H_2 O □(→┴yields )

Answer 1

\[P_4 O_10+ H_2 O (→┴yields )\]

Answer 2

if you dont want numbers to be popping out like that use {} or _{} if you want to put more than one thing in the ugh mind blanking subscript

Answer 3

Do you have any guesses as to what the product will be? Hint it is a molecule that you have probably seen before

Answer 4

also look at the structure, it is essentially a bunch of a common polyatomic ion bonded to itself

Answer 5

\[P_{4}OH _{2}\]
I THINK @Australopithecus

Answer 6

No I'm sorry that is incorrect, have you learned about polyatomic ions?

Answer 7

and strong acids/bases?

Answer 8

You are close though

Answer 9

guess once more, if you want to ace basic chemistry memorizing this list can be really helpful, http://www.avon-chemistry.com/common_ion.jpg

Answer 10

but yeah consult this list

Answer 11

and im sure you can guess as to what the answer is :)

Answer 12

IM TRYING =D

Answer 13

look for a polyatomic ion that has phosphorous and oxygen

Answer 14

if you cant guess I can give you another hint :)

Answer 15

Just a quick definition a polyatomic ion is one that is stable and normally stays intact

there is only two on that table that have phosphorous and oxygen, PO4^-3 and P2O7^-4,

Answer 16

\[H _{2}P0_{4}\]

Answer 17

should be H3PO4 because PO4 has a -3 charge

Answer 18

but still good :) so you have your product

Answer 19

this is called a dehydration reaction, H3PO4 is actually used in desiccators, but I'm sure not often it isnt that great as a dehydrator but I digress

Answer 20

now all you need to do is balance your reaction

Answer 21

You tube is great for stuff like this

you can watch these videos for methods:

Answer 22

also if you want another study tip memorizing all the strong acids and bases is also helpful,

Answer 23

if you want to check your balancing you can go to this website,

I hope this is helpful for you if you have any further questions please feel free to ask :)

Answer 24

THANKS

Answer 25

I only recommend memorizing this stuff because it is actually really useful if you ever want to work in a science lab, you run into these chemicals all the time or chemicals containing these polyatomic ions, so if someone asks you to grab some calcium carbonate you know right away. Further more it makes solving these stupid reaction equations much easier

Answer 26

not that the reactions themselves are stupid some of them are actually interesting in a practical sense if you read up on them.

Answer 27

Why is the product H3PO4?

Answer 28

is that what you wanted to ask?

Answer 29

@Australopithecus yes, why not

Answer 30

because P4O10 is just 4 phosphate atoms bonded to eachother

Answer 31

Well maybe that is not the best explanation

I'm not learned enough in Inorganic chemistry to really give you an accurate rationale, if one even exist I do not know.
