What is the Independent Variable for this scenario? * Thomas became interested in insulation while his family built a new home.
He decided to test the different types of insulation his family bought by filling a jar half full of
cool water, sealing the jar with a plastic lid, and then wrapping the jar with 400 g of
insulation his dad bought.
He then wrapped 2 other jars with other brands of insulation (400 g of insulation, half-filled
with water and sealed with a plastic lid).
A fourth jar was filled half-full of water, sealed with a plastic lid, and was not wrapped in
insulation
He placed all 4 jars in direct sunlight. He recorded the change in temperature every 5
minutes for 1 hour
1. Type of insulation
2. Amount of insulation (400 g)
3. Temperature of water
4. Amount of water
5. Amount of sunilght

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
