Answer: (a) The reaction mixture will proceed toward products.
Explanation:
Equilibrium constant is defined as the ratio of pressure of products to the pressure of reactants each raised to the power their stoichiometric ratios. It is expressed as
K is the constant of a certain reaction when it is in equilibrium, while Q is the quotient of activities of products and reactants at any stage other than equilibrium of a reaction.
For the given chemical reaction:
The expression for is written as:
Thus as , the reaction will shift towards the right i.e. towards the product side.
Answer:
A.) Adding more of gas C to the system
Explanation:
A.) is correct because the reaction wants to keep the same amount of reactants and products that sustain equilibrium. If you are increasing the amount of gas C, this will push the reaction to make more of the reactants to restore the balance.
B.) is incorrect because heat is a form of energy. As previously stated, when you add more material to the reactants side, the equilibrium shifts to the product side to restore equilibrium.
C.) is incorrect because when the volume is increased, the equilibrium will shift to the side with the greater amount of moles of gas. There is 1 mole of gas on the reactant side (from A (g)) and 3 moles of gas on the products side (from 3 C (g)). Therefore, the reaction will shift to the product side.
D.) is incorrect because if the material on the product side is decreasing, the equilibrium will want to make up that difference by shifting to the product side.
Remember,
reactants ---> products
when you hit a chemical with hammer and it was frozen only its physical properties will change and not he chemical properties,
when heated it may decompose to other chemical
when you hit with hamer it physical appearance will change but it remains chemically the same
when you put in salt solution , it wil interact with ions and its chemical properties changes
similarly when it was frozen, it retains its chemical properties.
Answer:
they don't
Explanation:
sodium chloride is an entirely different substance frim sodium and chlorine.
sodium is a metal, chlorine is a non metallic gas.
sodium chloride is a salt.

A chemical is classified as being volatile if it is readily evaporated at room temperature. <span>Volatility is related to a substance's </span>vapor pressure<span>. At a given temperature, a substance with higher vapor pressure vaporizes more readily than a substance with a lower vapor pressure.</span>
