In the Flame test, what could be done to test for the emission of anions? What are four uses for copper? What is simple distillation useful for? Why is it necessary to heat the naphthalene in a beaker of water? Why do different metal ions give different colors based on flame test?
What are the classes of non-silicate minerals? What negative ion forms the basis of the oxide minerals? What is the formula for calcium nitrate? What is the chemical formula for the ionic compound calcium chloride? What is the difference between oxides and sulfates?
There is a special type of bonding based on ions. This bonding, known as ionic bonding, is caused by the electrostatic attraction between positive and negative ions. This sort of bond usually occurs when two atoms come into contact and an electron from the valence shell of one jumps to the...

What is a Unit Cell? - The unit cell must construct the Bravais lattice by repeating itself in space. However, nothing is said about the number of points that must be contained within the unit cell. Lithium metal crystallizes in a body centered cubic cry
If 25.0 mL of urine has a mass of 25.725 g and contains 1.929 g of urea, what is the molarity of urea in the specimen? (Assume the rest of the urine is water.) Urea: Urea is a nitrogenous compound formed in the...
i am re-learning how to take care of my fish so thanks
Instead of 6 M HNO3 being added to the solution, 6 M HCl is added (both are strong acids). How will this affect the test for the presence of copper(II) ion in the solution? Explain. A cleaning solution is found ...
titration becomes unrealistic. The used metal ion must have less stability than the analyte. Another method of direct titration is the potentiometric method, used for endpoint detection with metal ions that have specific available electrodes. The endpoint is the point where the titration process ends...
