Answer 5

Ugh I don't know this sorry :3

Answer 6

k thanks

Answer 7

No prob sorry I couldn't be of more help :)

Answer 8

I can't see the latex code

Answer 9

As.2S.5+HNO.3→H.3AsO.4+NO.2+H.2SO.4+H.2O

I put a period right before the number got small

Answer 10

Why do you call it a simple _maths_ balance eq. Isn't this chemistry?

Answer 11

I was thinking that but I don't really know this stuff so I didn't want to give a wrong opinion.

Answer 13

@mathstudent55 its chemistry if u see basically but adding no. is maths thats why i used eq. and its not simple

Answer 14

\[As_{2}S_{5} + HNO_{3} \rightarrow H _{3}AsO _{4} + NO _{2} + H _{2}SO _{4} + H _{2}O\]
\[x(As_{2}S_{5}) + y(HNO_{3}) \rightarrow z(H _{3}AsO _{4}) +p( NO _{2}) +q( H _{2}SO _{4})+r(H _{2}O)\]
LEFT SIDE RIGHT SIDE
As 2x = z
S 5x = q
H y = 3z+2q+2r
N y = p
O 3y = 4z+2p+4q+r
from which we obtain the homogeneous linear system
2x -z = 0
5x -q = 0
y -3z -2q -2r = 0
y -p = 0
3y -4z -2p -4q -r = 0
the augmented matrix for this system is:
\[\left[\begin{matrix}2 & 0&-1&0&0&0&0 \\ 5 & 0&0&0&-1&0&0\\0&1&-3&0&-2&-2&0\\0&1&0&-1&0&0&0\\0&3&-4&-2&-4&-1&0\end{matrix}\right]\]

Answer 15

solve for that matrix by reduced row echelon form, you can get what you called "simple math balance" hehehe

Answer 16

yoh thanks @loser66
