SO3 + NO <==> SO2 + NO2
1.7M + xM |=| 0.070M + 1.3M
Keq = 10.8 = [SO2]*[NO2] / [SO3]*[NO] = 0.070*1.3 / 1.7*x
Solving x (concentration NO at eq.) 10.8 * (1.7*x) = 0.070*1.3
x = 0.0091 / 18.36 = 0.000496 = 0.00050 M = 0.50 mM
H20S04 is a chemical mixture. This mixture contains hydrogen, oxygen, and ascorbic acid. This mixture is still be tested on different things so is not commonly used right now.
A homogenous mixture is one containing a number of particles of the same substance, while a heterogenous mixture contains particles of different substances. For example, a handful of sand would probably be considered a homogenous mixture because it only contains sand particles, while a handful of mud would be a heterogenous mixture because it contains particles of dirt, water, sand, rocks, etc.
Distilled water is usually a pure substance. Occasionally it contains a very small amount of chloride ions, and then it is an homogeneous mixture.
mixture, definitely. unpolluted rainwater has water, carbonic acid (from dissolved carbon dioxide in the atmosphere), dust, and maybe other things
C2H6 (ethane) is neither a mixture nor an element. It is a molecular compound since it contains different atoms but is not mixed with other compounds.
concentration decreases
A numerically large equilibrium constant (Keq) indicates that the equilibrium lies far to the right, with more products present at equilibrium than reactants. This means that the forward reaction is favored, leading to a higher concentration of products compared to reactants in the equilibrium state.
Adding a catalyst to the mixture would not affect the equilibrium concentration of H2O. A catalyst speeds up the rate of the forward and reverse reactions equally, without changing the position of the equilibrium. This means that the equilibrium concentration of H2O would not be affected by the presence of a catalyst.
If the Kc expression is greater than 1 in chemistry, it means that the concentration of products in the equilibrium mixture is higher than the concentration of reactants. This suggests that the reaction favors the formation of products at equilibrium.
The dissociation constant describes the extent to which a compound breaks apart into its ions in a solution, specifically for weak acids or bases. The equilibrium constant, on the other hand, describes the ratio of product concentrations to reactant concentrations at equilibrium for a chemical reaction.
A quantity that characterizes the position of equilibrium for a reversible reaction; its magnitude is equal to the mass action expression at equilibrium. K varies with temperature.
Cooling the equilibrium mixture will shift the equilibrium towards the side favoring the formation of the reactants (endothermic direction). The intensity of the mixture color could decrease if the reactants are colorless or have a lighter color compared to the products.
A small equilibrium constant (Kc) typically indicates that the reaction tends to favor the reactants at equilibrium rather than the products. This suggests that the reaction is not proceeding to a significant extent in the forward direction.
Loam contains a mixture of sand, silt, clay and humus in relatively even concentrations (about 40-40-20% concentration respectively).
The system will rebalance.
To ensure that you have the more product which will be produced because the equilibrium will shift to produce it. This will produce heat and also more chemical product that you want in the equilibrium mixture.
If you add energy to one side of a dynamic equilibrium, the equilibrium will shift in the direction that consumes or uses up that energy to try and counteract the change. This shift will help to restore the equilibrium by balancing out the energy input.
