False we use it to detirmine the reactivitys and what groups they are in
it is a great change because the salt goes in and turn the water to salt water
The chemical formula for ammonia is NH3. So first, you need to find the molar mass of ammonia (how many grams in one mole).
N=14g
H3=3g
So one mole of NH3 is 17 grams, you can divide 82.9 grams by 17 grams to find the number of molecules. The answer should be 4.876 moles (molecules) of ammonia. Hope this helps!
Aqua Auras belong to the Quartz family. It's a synthetic type of Quarts that was enhanced with the help of gold coating, and sometimes other materials. The reason why it's called as aqua is because of its distinctive blue color thanks to the procedure which made it.
Answer:
Density = mass / volume,
therefore volume = mass / density. Note that 1 mL = 1 cubic centimeter.
Explanation:
Volume = 15.1g / 3.52g/mL = 4.3mL = 4.3 cubic centimeters.
then a diamond has a density of 3.52 g/mL.
