Using the solubility curve, choose all of the statements that are correct. The solubility of NaCl is least affected by temperature you can completely dissolve 60 g of KBr in 100 g of water at 20 °C the solubility of KNO3 is the least affected by changes in temperature 100 g of KBr will dissolve completely in 100 g of water at 75 °C if you mix 120 g of NaClO3 in 100 g of water at 10 °C, approximately 30 g will not dissolve

The key to stability is feedback between the reservoir and the fluxes into and/or out of the reservoir. assume that the rate of outflow from a reservoir depends on the size of the reservoir according to the following relationship: outflow rate= k x (size of reservoir), where k is a constant. a reservoir of water has a volume of 5000 liters, and the rate of outflow at steady state is 25 liters per minute. what is k? (give both the numerical value and its units.) what is the residence time? what is the relationship between k and the residence time?

If vx = 7.00 units and vy = -7.60 units, determine the magnitude of v⃗ . determine the direction of v⃗ .

How is coal extracted from mountaintop removal mines? a. dynamite is used to create underground tunnels where miners go to extract the coal. b. dynamite is used to break apart rocks and then draglines are used to remove the broken rock and reach the coal. c. coal in mountaintops is extracted by digging strips in the landscape to reach the coal. d. placer deposits in mountain river bottoms are removed by
