Answer:
Physics is a natural science that involves the study of matter and its motion through space and time, along with related concepts such as energy and force. More broadly, it is the study of nature in an attempt to understand how the universe behaves.
Explanation:
Pressure =vapor pressure of 2 methlypentane at 150F. If you
Answer:
Compound
Explanation:
Soda itself is a mixture made out of compounds.
Answer: The initial partial pressures of 
and 
is 139.4 torr.
Explanation:
The equilibrium reaction is
initially conc. p p 0
At eqm. p-2x p-x 2x
Given: 
The expression for equilibrium constant is :
= 2x =115 torr
= (p-2x) = p-115 torr
= (p-x)= p-57.5 torr
Now put all the given values in this expression, we get
Therefore, the initial partial pressures of and is 139.4 torr.
The mole ratio Aluminium to Aluminum Oxide is 2 : 1
<h3>Further explanation</h3>
Given
Reaction
2Al + Fe ----> Al2O3 +2Fe
Required
The mol ratio
Solution
If we look at the reaction above, there is an element missing from the reactant i.e oxygen, because the number of atoms and elements involved in the reaction should be the same between the reactants and products.
So the possible and balanced reactions are:
<em>2Al(s) + Fe₂O₃ (s) → Al₂O₃ (s)+ 2Fe (s) </em>
From this reaction the ratio of Al: Al₂O₃ can be determined, which is 2: 1
