Answer:
The smallest possible inside length of the tank is 
m.
Explanation:
As we know that
Thus, volume of 
liter tank is also equal to 
cubic meter
The volume of a cube is equal to 
, where, x is the length of the side of the cube
With the give condition,
Solving the above equation, we get -
The smallest possible inside length of the tank is m.
Answer:Displacement method
Explanation:
Answer: 1.5 moles O2
Explanation:
The number of moles of each reactant and product is the number in front to the molecule when the equation is balanced.
You know that 1 mole of O2 gives you 2 moles of H2O
So you can set up a proportion using that.
1 mole O2. X moles O2
-------------- = -------------------
2 moles H2O. 3 moles H2O
Then cross multiply
2x=3
X=3/2 Or 1.5
So you need 1.5 moles O2 to get 3 moles of H2O.
