Question

(I know this is totally irrelevant but hardly anyone is on Chemistry)
Write a chemical equation for the combustion of each of the following substances. If a compound contains carbon and hydrogen, assume that carbon dioxide gas and liquid water are produced. (Use the lowest possible whole number coefficients. Include states-of-matter under the given conditions in your answer.)

(a) solid barium

Answer 1

Well, what do you think?

Answer 2

I honestly have no clue as to what I should do

Answer 3

\[\rm Ba ~(s) + O_2~(g) \longrightarrow \cdots \]

Answer 4

Ba_{2}O(s)?

Answer 5

\[Ba _{2}\]

Answer 6

In elemental states, you're looking at reactions like these:\[\rm C~(s) + O_2~(g) \longrightarrow CO_2~(g) \]\[\rm Na + O_2 \longrightarrow Na_2 O \]\[\rm N + O_2 \longrightarrow NO_2\]

Answer 7

Why \(\rm Ba_2 O \)? Why not \(\rm Ba_2 O_3\) or \(\rm BaO_2\) or \(\rm BaO\)?

Answer 8

Oh yeah then BaO right?

Answer 9

Since Ba has a +2 charge and O has a -2 charge

Answer 10

right?

Answer 11

Hello?

Answer 12

Yes, right!

Answer 13

Yay!

Answer 14

So for my other questions do I just add \[O _{2}\]

Answer 15

because that was the main place as to where I was confused

Answer 16

That's what combustion is, right?

Answer 17

I think my teacher didn't cover this too thoroughly and he moves from subect to subject pretty quickly as well

Answer 18

Anyways thank you so much!!!!

Answer 19

No problem :)
