Which of the following statements are true about molarity and dilution? (Select all that apply.) Molarity is one of many ways to measure the concentration of a solution. The molarity equation can be algebraically rearranged to give the following relationship: moles (M / Liters). The molarity equation can be algebraically rearranged to give the following relationship: Liters (M * moles). Molarity is defined as the number of moles of solute per liter of solvent. When diluting a solution by adding water the number of moles...

Which of the following statements is true about chemical equilibrium? Select all that apply. At chemical equilibrium, the reactants have been completely consumed. At chemical equilibrium, both reactions stop completely. At chemical equilibrium, the concentrations of the species involved in the reaction stay constant (in the absence of an external perturbation). At chemical equilibrium the rate of the forward reaction is equal to the rate of the reverse reaction.

Which of the following statements about equilibrium expressions and equilibrium constants are correct? Choose all that apply. Check all that apply. For chemical reactions in which all reactants and products are gases, K. can never be equal to K The equilibrium expression for a reaction involving only gases can be written in terms of either partial pressures or concentrations. A homogeneous equilibrium is one where all reactants and products are in the same physical state, When a chemical reaction is...

Which statements about lenses are true? (SELECT ALL THAT APPLY) options: Convex lenses are used to make magnifying glasses. Lenses operate on the principle of refraction. All images formed by lenses are real. Only mirrors make virtual images. The thin lens equation is mathematically the same as the spherical mirror equation.

Which of the following statements is true for real gases? Choose all that apply. As molecules increase in size, deviations from ideal behavior become more apparent at relatively low pressures. The volume occupied by the molecules can cause a decrease in pressure compared to the ideal gas. As molecules increase in size, deviations from ideal behavior become more apparent at relatively high pressures. The volume occupied by the molecules can cause an increase in pressure compared to the ideal gas.
