Answer:
You will change which food dye is used. You will measure how quickly the dyes diffuse. You could use a timer to see how long the dye takes to completely diffuse.
The a metal tank containing hydrogen gas has a pressure gauge that reads 575 psi, 120 pressure inside of the tank.
What is pressure gauge?
A device used to measure a fluid's (liquid or gas') state by calculating the force the fluid would apply to a unit area if it were at rest.
What is pressure?
The force of all gas particle/wall collisions divided by the surface area of the wall is the definition of pressure (P): One of the fundamental quantifiable variables.
Therefore, a metal tank containing hydrogen gas has a pressure gauge that reads 575 psi, 120 pressure inside of the tank.

the mass of aluminum oxide (101.96 g/mol) produced from 1.74 g of manganese(iv) oxide (86.94 g/mol) is 1.36g
The reaction is 3 MnO2 + 4 Al ------ 2Al2o3+ Mn
3 mole of manganese oxide give 2 moles of aluminum oxide so by the reaction n( MnO2)/3 =n(al203)2
the formula is n= mass/M so, now substituting values
m (Al2O3)= m(MnO2) X 2 X M (Al2O3) / M(MnO2 X3
so, by substituting values, 2 X101.96 X1.74g / 3 X 86.94 =1.36g
so mass of aluminum oxide obtained = 1.36g
