Gases A, B, C, and D are related by the following reversible reaction: A + B ⇌ C + 2D

Write the expression for the equilibrium constant for this reaction.

At a certain temperature, the concentrations of A, B, and C are 0.54M, 0.34M, and 0.46M, respectively. The Keq for this reaction is 1.6. Find the concentration of D.

The air exhaled from the lungs of a smoker has a concentration of 24 ppm co. express the concentration as a percent.

The diagrams show objects’ gravitational pull toward each other. which statement describes the relationship between diagram x and y? gravity attracts only larger objects toward one another. gravity attracts larger objects only if they are close to one another. if the masses of the objects increase, then the force between them also increases. if distance between the objects increases, then the amount of force also increases.
