Is calcium cheap or expensive?
or
Is calcium carbonate cheap or expensive?
or
Which is more expensive sodium chloride or calcium chloride?
The price is higher for the calcium chloride.
How valuable is calcium?
It is yummy, and very good for you, so good things are expensive, so calcium is too =]
What are the ingredients of ice melting salt?
We can use sodium, calcium and potassium chlorides; NaCl is the cheapest, calcium chloride is the most efficient but is more expensive.
What is the best salt to use on roads?
The best is calcium chloride; but because this is expensive rock salt is used.
Protect human bones?
Calcium with magnesium. No sense in buying expensive versions of calcium supplements. Try green leafy vegetables. If you use a calcium supplement calcium carbonate is fine. Calcium citrate maleate is quicker absorbing but unless you plan on getting osteoperosis in the next two days that shouldn't matter. And wear a seatbelt and helmet.
Which is better for melting ice CaCl3 or NaCl?
Calcium chloride is better (the solubility heat is greater) but is more expensive.
Why does sodium chloride melt ice faster than calcium chloride and magnisium solfate?
It is not correct: calcium chloride is more efficient (but also more expensive); the cause is that the CaCl2 enthalpy of dissolution is higher.
Your female pit bull just had 13 puppies for her first litter what should you do?
give her calcium supplements and/or feed her puppy chow and milk. That many puppies can suck the calcium from her and kill her. First, she will start seizuring. Then, you have 12 hours to get her help. The vet bill will be expensive.
How is sodium metal prepared?
Using Downs process, by the electrolysis of molten sodium chloride. This is done in a Downs Cell in which the NaCl is mixed with calcium chloride to lower the melting point below 700 °C. As calcium is less electropositive than sodium, no calcium will be deposited at the cathode. This method is less expensive than the previous Castner process of electrolyzing sodium hydroxide.
Why is analytical grade calcium carbonate more expensive than laboratory grade?
Grades of purity apply to all substances, not just calcium carbonate. Laboratory grade is generally about 99.8% pure, analytical grade is specifically 99.9999% pure (aka 6 nines pure).
