A gas has a solubility in water of 11.9 g/L at 15°C and 505 kPa of pressure. What is the pressure of the gas, in atm., (at the same temperature) if the solubility of the gas is 20 mg/L? 734 grams of lithium sulfate are dissolved to make 2500.0 mL of solution. What is the Molarity of this Solution

Describe the process you would follow to prepare 120 ml of a 2.0 M solution of HCl if you started with a 6.0 M stock solution.

What is the percent (mass/volume) if 12 g of KCl is added to 50 mL of water to make 93 mL of solution?

If 75 g. of Potassium Chloride (ionic compound) is dissolved in 250 grams of water, what will be the freezing point of the solution? Kf = 1.86

The vapor pressure of pure water is 3.17 kPa. What will be the vapor pressure of a solution containing 13 g. of potassium permanganate (KMnO4) and 750 g of water?

The answer is c.  na2haso4  and na2so4

Part 1: which process does arrow f represent? part 2: explain how matter is conserved during the process.part 3: justify why this process is a recycling of carbon in the carbon cycle.  use complete sentences to explain your answer.

Starsstars are giant balls of hot gases that can produce their own light. stars give out energy by converting hydrogen gas into helium in their cores. stars are gigantic in size and have immense gravitational attraction. the sun is a medium sized star that gives us energy and makes life on earth possible.planetsplanets are large (almost) spherical objects that revolve around the sun. planets move in fixed orbits around the sun. there are 8 planets in our solar system. planets may be made of rocks, metals, gases like hydrogen, nitrogen and methane. the earth is also a planet and is the only place in the universe that we know that supports life. planets that revolve around other stars are called exoplanets.satellitessatellites are objects that revolve around planets. they form the essential part of the celestial bodies. these may be of natural origin or sent by humans. the moon is a natural satellite of the earth and revolves around it because it is bound by the earth’s gravitational pull. man also has placed artificial or man-made satellites around the earth and other planets to study them and for communication purposes.i think this is correct not 100%
