Answer:
Explanation:
By rearrangement of atoms of reactants. The entire properties will also different from the reactants as the composition changes.
we cant
Explanation:
you need to leave some water to stop dehydration of substance
Answer: The equilibrium will shift to the left to favor the reverse reaction.
Explanation:
This is a direct application of Le Chatelier's principle.
Le Chatelier's principle predicts that if a chage is introduced in a system in equilibrium, the system will react to compensate the change.
The increase in the concentration of CO, which is in the right side of the chemical equation, takes the system out of the equilibrium.
Chemically, the greater number of molecules of CO means that more CO will react to favor the reverse reaction and restore the equilibrium with the increase of molecules in the left side (CH4 and H2O).
Answer:
by using ideal gas law
Explanation:
ideal gas law:
PV=nRT
where:
P is pressure measured in Pascal (pa)
V is volume measured in letters (L)
n is number of moles
R is ideal gas constant
T is temperature measured in Kelvin (K)
by applying the given:
P(initial) V(initial)=nRT(initial)
P(final) V(final)=nRT(final)
nR is constant in both equations since same gas
then,
P(initial) V(initial) / T(initial) = P(final) V(final) / T(final)
then by crossing multiply both equations
V (final)= { (P(initial) V(initial) / T(initial)) T(final) } /P (final)
P(initial)=P(final)= 1 atm = 101325 pa
V(initial)= 6 L
T(initial) = 28°c = 28+273 kelvin
T(final) = 39°c = 39+273 kelvin
by substitution
V(final) = 6.21926 L
Your answers are correct. I love the Universal formula.
