If an object that stands 3 centimeters high is placed 12 centimeters in front of a plane mirror, how far from the mirror is the image located? Explain your reasoning.
An object with a height of 0.3 meter is placed at a distance of 0.4 meter from a concave spherical mirror. An image with a height of 0.1 meter is formed in front of the mirror. How far from the mirror is the image located?
When an object with a height of 0.10 meter is placed at a distance of 0.20 meter from a convex spherical mirror, the image will appear to be 0.06 meter behind the mirror. What’s the height of the image?
Compare and contrast the properties of the images formed by each mirror type in the table.

Image Formation
Mirror Type Appearance Placement Size
Plane
Concave (when the object is located a distance greater than a focal length from mirror's surface)
Concave (when object is located a distance less than the focal length of the mirror)
Convex

Nconcentration refers to the molar concentration of an ion in solution. it may be identical to, or greater or less than, the molar concentration of the compound containing the ion that was used to make the solution. for soluble salts, the molarity of a particular ion is equal to the molarity of that compound times the subscript for that ion. for example, 1 m of alcl3 is 1 m in al3+ and 3 m in cl−. 1 m of (nh4)2so4 is 2 m in nh4+ and 1 m in so42−. part a what is the concentration of k+ in 0.15 m of k2s? view available hint(s) nothing m m part b if cacl2 is dissolved in water, what can be said about the concentration of the ca2+ ion? view available hint(s) if is dissolved in water, what can be said about the concentration of the ion? it has the same concentration as the cl− ion. its concentration is half that of the cl− ion. its concentration is twice that of the cl− ion. its concentration is one-third that of the cl− ion. part c a scientist wants to make a solution of tribasic sodium phosphate, na3po4, for a laboratory experiment. how many grams of na3po4 will be needed to produce 550 ml of a solution that has a concentration of na+ ions of 0.700 m ? express your answer numerically in grams. view available hint(s) mass of na3po4 n a 3 p o 4 = nothing g provide feedback
