Answer:
90.5mL is the volume of the gas at STP
Explanation:
It is possible to find volume of a gas when conditions of temperature and pressure change using combined gas law:
Where P is pressure, V is volume and T is absolute temperature. 1 is initial conditions and 2 final conditions.
If initial conditions are 1.08atm, 80.0mL and absolute temperature is (-12.5°C + 273.15) = 260.65K.
And STP are 1atm of pressure and 273.15K of absolute temperature. Replacing:
V₂ = <em>90.5mL is the volume of the gas at STP</em>
It can uplift slowly due to the pressure of Earth’s plates.
It can melt into magma and recrystallize as extrusive igneous rock.
Know what decomposition is. The compound is "breaking down".
Di means 2 while, Tetra means 4.
First, we will simply follow the instructions and break down the compound as so: The decomposition of dinitrogen tetraoxide into nitrogen gas and oxygen gas
*Take into account that diatomic molecules (HNOFClBRI) will always have a subscript of 2
N₂O₄⇒N₂+O₂
After breaking down the compound, we must now balance the equation.
To balance the equation, we must make sure that each element has the same amount of atoms.
Starting with compound at the left of the yield: N=2 and O=4
But, at the right of the yield: N=2 and O=2
We have now discovered that the oxygen gas is not balanced throughout the equation.
N₂O₄⇒N₂+2O₂
*We simply multiply the oxygen gas on the right of the equation by 2
After multiplying, on the right side of the equation, O=4. We now have a balanced equation because all elements have the same amount of atoms on each side.
So your final answer for this balanced decomposition chemical equation is: N₂O₄⇒N₂+O₂
They are pretty much the cause and effect. The independent variable that is being changed in the experiment, so it is the cause. The dependant variable is the result of change the independant variable, so the effect.
