Balanced chemical reaction: C₃H₈(g) + 5O₂(g) → 3CO₂(g) + 4H₂O(g).
<span>There are same number
of atoms of on both side of balanced chemical reaction: ten oxygen atoms, three carbon atoms and eight hydrogen atoms.
</span>Carbon is oxidized and oxygen is reduced in this balanced chemical reaction of combustion of propane.
Answer:0.86
Explanation:
A mixture of methane gas, CH4(g), and pentane gas, C5H12(g), has a pressure of 0.5922 atm when placed in a sealed container.Lets suppose initially partial pressure of CH4 is x and C5H12 is y
x+y=0.5922-----i
1.CH4[g] + 2O2[g] -> CO2[g] + 2 H2O[g]
2.C5H12 + 8O2 → 5CO2 + 6H2O
partial pressure of CH4 is x produce xatm of CO2 and 2xatm of H2O
x + 2x = 3 atm
partial pressure of C5H12 is y produce 5yatm of CO2 and 6yatm of H2O
5y+6y=11y
so the final partial pressure of product mixture will be
3x + 11y = 2.429atm ------ii
solve eq i for x and put in ii
x=0.5922-y -----iii
3(0.5922-y)+ 11y = 2.429atm
y= 0.8155atm
put in iii
x=0.5922-0.8155
x= 0.51atm (Partial pressure of CH4)
mol fraction of CH4=Partial pressure/
Total pressure
=0.51/0.5922
=0.86.
Answer:
Molecular- compound B, Ionic - compound A
Explanation:
Molecular compounds are compounds containing two or more non-metal for example carbon dioxide and covalent in nature. They usually have low melting and boiling points and will vaporized faster. Compound A on the other hand is ionic; they usually have high melting and boiling points and when dissolved in water they dissociate into ions ( actions and anions)
Among the following options eating an energy bar by a hiker using a chemical potential energy.
<h3>Wha is chemical potential energy ?</h3>
Chemical potential energy is the energy stored in the chemical bonds of a substance.
The food we eat contains stored chemical energy.
As the bonds between the atoms in food loosen or break, a chemical reaction takes place, and new compounds are created.
The energy produced from this reaction keeps us warm, helps us move, and allows us to grow
Hence, eating an energy bar by a hiker using a chemical potential energy.
