Balance this equation: Al+ HNO3 H2 + Al(NO3)3

2Al+ 6HNO3 3H2 + 2Al(NO3)3

Explanation:

Put coefficient a,b,c, and d for calculation:

a Al + b HNO3 = c H2 + d Al(NO3)3

for Al: a = d

for H: b = 2c

for N: b = 3d

for O: 3b = 9d

Suppose a=1, then d=1, b=3, c=3/2

multiply 2 to make all natural number, a=2, then b=6, c=3, d=2

it should have an internal chamber and two thermometers sticking out of the top. the internal chamber will also be closed off from the outside.
