What else can I help you with?
What is the molarity of chloride ion in 100 ml of a 500 M barium chloride solution?
I assume you mean 0.5 molar, but I'll go with what I'm given. If you have 500 molar of barium chloride, you will have 1000 molar of chloride ions as there are 2 chlorides for every 1 molecule of barium chloride. Having the 100ml there is irrelevant as you are talking about concentration and didn't ask for moles.
Is there benefit to adding saline to a ventolin nebulizer treatment?
Ventolin contain an isotonic solution of salt; I assume that pharmacists have thought better. Sodium chloride has also an antibacterial effect.
Is magnesium chloride acid base or neutral in water?
Theoretically, the magnesium ion undergoes a tiny amount of hydrolysis. But this amount is so small that it realistically has no effect on the solution. So, in reality, it is neutral.
Now assume you measure out exactly 2.0 ml of aluminum chloride into a third test tube How many moles of aluminum chloride are in the tube?
To calculate the number of moles of aluminum chloride in the test tube, you need to know the molar mass of aluminum chloride (AlCl3). The molar mass of AlCl3 is 133.34 g/mol. Given that you have 2.0 ml of AlCl3, you will need to convert this volume to grams using the density of AlCl3. Finally, you can calculate the moles using the molar mass.
How much heat is absorbed by 100 mL of a dilute solution of NH4NO3 as it changes its temp from 25.3 Celsius to 22.4 Celsius?
The heat absorbed can be calculated using the formula q = mcΔT, where q is the heat absorbed, m is the mass in grams (100 mL of NH4NO3 is approximately 100 g), c is the specific heat capacity of the solution, and ΔT is the change in temperature. Given that the specific heat capacity of NH4NO3 solution is about 4.18 J/g°C, you can plug in the values to find the heat absorbed.
How do you calculate Specific fuel Consumption boiler?
if a gas boiler is capacity of 20 ton & steam pressure is 13 bar,how much fuel consume it??if other requirments need assume please.
The blue color in the copper sulfate solution is due to the presence of what ion?
Since copper (I) chloride has only limited solubility in water I will assume you mean copper (II) chloride, CuCl2. Then the ions will be Cu2+ and Cl-.
What is the chemical formula for sodium clorde?
I assume that you mean sodium chloride, in which case the chemical formula is NaCl.
Capacity of Propane tank with gross water capacity of 285 gals?
Assume liquid propane has a specific gravity of .51. For a liquid with that property DOT regulations say that for tanks under 1200 gallons, the maximum permitted filling density of the tank is 42% of the water weight capacity. Assume water weighs 8.33 lbs/gal. 285 x 8.33 = 2374 lbs capacity. 2374 x .42 = 997 lbs.
Which liquid has a specific gravity greater than 3.52?
Specific gravity relative to what? I assume you mean water. Bromine has a density of 3.11 gm/c^3, which is 3.11 times that of water. That could work for whatever you are doing.
What is the mass percentage of chloride ion in the seawater if its density is 1.025?
The average chloride ion concentration in seawater is around 1.93% by mass. Therefore, if we assume that all the chloride ions are contributed by sodium chloride (NaCl), which has a molar mass of 58.44 g/mol, the mass percentage of chloride ion in a seawater sample with a density of 1.025 g/mL is approximately 1.98%.
What metric unit of capacity is used to measure small amounts?
I assume you mean volume rather than capacity. The milliliter would be the best answer. It is 1 thousandth of a liter.
