The balanced chemical reaction will be:
C3H8 + 5O2 = 3CO2 +4H2O
We are given the amount of oxygen gas to burn the propane gas. This will be our starting point.
34.0 L O2 ( 1 mol O2 / 22.4 L O2 ) (1 mol C3H8 / 5 mol O2 ) ( 22.4 L C3H8 / 1 mol C3H8) = 6.8 L C3H8
The given question is incomplete. But the complete question is this:
A mixture of and is passed over a nickel catalyst at 1000 K. The emerging gas is collected in a 5.00-L flask and is found to contain 8.62 g of CO, 2.60 g of , 43.0 g of , and 48.4 g of . Assuming that equilibrium has been reached, calculate for the reaction.
Explanation:
As the given reaction is as follows.
And, we know that
No. of moles =
Therefore, calculate the moles as follows.
Moles of =
= 2.6808 mol
Moles of =
= 2.6866 mol
Moles of CO =
= 0.307747 mol
Moles of =
= 1.2897 mol
As, we know that
Concentration =
Given volume = 5 L
Hence, calculate the concentration of given species as follows.
Conc. of
= 0.5361
Conc. of
= 0.5373
Conc. of CO =
= 0.06155
and, Conc. of
= 0.2579
Now, expression for equilibrium constant for the given reaction is as follows.
Now, putting the given values into the above formula as follows.
Also, we know that
Consider the equation
Calculate change in moles of gas as follows.
change in gas moles (dn) = 1 + 3 - 1 - 1
dn = 2
As,
It is given that,
T = 1000 K, R = 0.0821
So,
= 24.70
Thus, we can conclude that value of for the reaction is 24.70.
Answer: An atom a fundamental piece of matter. ... An atom itself is made up of three tiny kinds of particles called subatomic particles: protons, neutrons, and electrons. The protons and the neutrons make up the center of the atom called the nucleus and the electrons fly around above the nucleus in a small cloud.
Explanation:
(2) 0.20 (4) 20.
Answer:The correct answer is (3).
Explanation:
The pH of the solution is defined as negative logarithm of or hydronium ions ions in the solution.
The pH with 10 times the concentration ions.
Hence, the correct answer is (3).
Answer:
Explanation:
That is a chemical property of alkali metals: they are highly reactive and react vigorously with water to produce the correspondant hydroxide and hydrogen gas.
These are some of those reactions:
The alkali metals are the elements of group 1 of the periodic table: Li, Na, K, Rb, Cs, and Fr. They have one valence electron which may lose easily to form an ion with charge +1.
Alkali metals react with water to produce hydrogen gas and a basic solution of the metal hydroxide (for instance, sodium hydroxide when lithium is in the reaction). This reaction signifies the easier oxidation of alkali metals compared to hydrogen.
When alkali metals react with water, they form hydrogen gas and a basic solution of the metal hydroxide. This vigorous reaction reveals that alkali metals are easier to oxidize than is hydrogen. For instance, considering the reaction of lithium with water:
2Li(s) + 2H₂O(l) --> 2NaOH(aq) + H₂(g)
The solid state (s) lithium reacts with liquid water to generate hydrogen gas and the ionic compound sodium hydroxide. This sodium hydroxide, which is a solid in its pure form, promptly dissolves in water.
The same kind of reaction occurs with other alkali metals and also some alkaline earth metals, although beryllium and magnesium are exceptions.
