If 0.278g of argon dissolves in 1.5 l of water at 62 bar, what quantity of argon will dissolve at 78 bar
irinina [24]
When P1/P2 = C1/C2

and C is the molarity which = moles/volume

so, P1/P2 = [(mass1/mw)/volume] / [(mass2/mw)/volume]

P1/P2 = (mass1/mw)/1.5L / (mass2/mw)/1.5L 

so, Mw and 1.5 L will cancel out:

∴P1/P2 = mass1 / mass2

∴ mass 2 = mass1*(P2 / P1)

                = 0.278g * (78 bar / 62 bar)

                = 0.35 g

∴ the quantity of argon that will dissolve at 78 bar = 0.35 g

Which of the following statements is/are CORRECT?1. For a chemical system, if the reaction quotient (Q) is greater than K, react
tankabanditka [31]

Explanation:

A chemical equilibrium is defined as the state of reaction in which the rate of forward reaction is equal to the rate of backward reaction.

When Q > K_{eq}, then it means that the reaction is proceeding in the backward reaction. Whereas if Q < K_{eq}, then it means that the reaction is proceeding in the forward direction. Hence, formation of products will be favored.

On the other hand, if Q = K_{eq}, then it means reaction is at equilibrium.

At equilibrium, it is not necessary that the concentrations of products divided by the concentrations of reactants equals one.

Thus, we can conclude that the statement for a chemical system at equilibrium, the forward and reverse rates of reaction are equal, is correct.

Which set describes the link between carbon dioxide and climate in a logical order?
nekit [7.7K]
Carbon dioxide, when excess in number, becomes a greenhouse gas According to sources, the most probable answer to this query is that carbon dioxide is one of the greenhouse gases that traps heat affecting climate. This increase in heat turns the temperature higher. Thank you for your question. Please don't hesitate to ask in Brainly your queries.
