What else can I help you with?
How many grams of nacl are needed to make 3L of 6M nacl?
Moles of NaCl=6*3=18mol Mass needed=[35.5+23]*18=1053g
Why is AgNo3 and NaCl least desirable?
These compounds react forming a white insoluble precipitate - silver chloride: NaCl + AgNO3 = AgCl + NaNO3
What is NaCl molecule or compound?
Sodium chloride is a compound forming large lattices.
What happens when you have NaCl and H20 and then heat it up?
first nothing seems to happend, but minutes later a sedimentation or deposit of nacl will be clearly seen. this nacl will be forming on the sorrounding of the recipient were you heat up the solution
What is the enthalpy of dissolution of NaCl in water?
The enthalpy of dissolution of NaCl in water is the amount of heat energy released or absorbed when NaCl dissolves in water.
How would you prepare 400ml of a 0.24M NaCl solution?
We first calculate the amount, in moles, of NaCl that we will need.Amount of NaCl needed = 0.24 x 400/100 = 0.096mol. Mass of NaCl needed = (23.0 + 35.5) x 0.096 = 5.616g So to produce 400ml of 0.24M NaCl solution, accurately add 5.616 grams of NaCl to 400ml of deionised water.
Is sodium chloride an example of a solution?
Sodium chloride is a solid but NaCl can be dissolved in water forming a solution.
What type of bond is NaCl and why?
Sodium chloride is a polar salt with ionic bonds, forming crystalline lattices.
What mass of water is needed to dissolve 292.5g of NaCl to produce 0.25 m aqueous solution?
m (molality)=moles of solute/kg of solvent To calculate moles of solute you convert 292.5 g of NaCl to moles of NaCl. So (292.5gNaCl)(1mole NaCl / 58.4gNaCl)= 5.0085 moles NaCl Now plug and chug. 0.25m=5.0085moles NaCl / x x=5.0085 moles NaCl /.25m x=20kg
Is a salt getting formed a chemical change or physical change?
I think it is a chemical change Forming underground it is a chemical change Salt forming from a saline solution for example h20 + NaCl --delta-> h2 + O2 + NaCl (This is not a balanced solution) This is a physical change, since there is no change to the Sodium Chloride
What mass of NaCl is needed to make 414 g of a 3.06 percent NaCl solution?
If your solution is a total of 414g and 3.06% of it needs to be NaCl, then you just take 414 x .0306 = grams of NaCl. The rest of the grams will be from other species in the solution.
What is cohesive energy in case of NaCl?
If you think to lattice energy the value is 789 kJ/mol.
