Measure the diameter of the circle using ruler a and ruler b. given that the actual diameter of the circle is 2.264 cmcm, classify the following statements that describe the diameter measurement of the circle according to the ruler. drag the appropriate items to their respective bins.

Ruler A :

According to ruler A, the diameter of the circle has only one certain digit and one uncertain digit. if we look at measurement of a diameter, it contain two significant figures. so the certainty  of the diameter measurement is smaller.

Ruler B :

According to ruler B, the certainty  of the diameter measurement is greater. because it contain two certain and one uncertain digit. it has three significant figures.

adding or remove a gaseous reactant or product changes the concentrations. if the concentration of reactant or product is increased, the system will shift away from the side in which concentration was increased (i.e. if the concentration of reactants is increased, the system will shift toward the products. if more products are added, the system will shift to form more reactants). conversely, if the concentration of reactant or product is decreased, the system will shift toward the side in which concentration was decreased (i.e. if reactants are removed, the system will shift to form more reactants. if the concentration of products is decreased, the equilibrium will shift toward the products).
