Answer: For this homework question, you’ll need to look up the molar mass of AgNO₃. Use this to calculate the number of moles in the sample.
Then note that silver is (quite usually) univalent, so there will be as many moles of AgCl as there were of AgNO₃.
Ask your instructor or tutor for more in-depth training, if need be. Good luck!
Explanation:
That wouod be the ionosphere!
Answer:
*Engineers can design better bridges because they know how metal changes shape.
*Scientists can easily classify mixtures of unknown substances.
Explanation:
Tensile strength and the properties of mixtures are physical properties because the substances are not changed into different ones.
A. and C. are wrong. Combustion and other reactions are chemical properties because the substances are changed into different ones
Answer:
Why do you like frogs?
Explanation:
(I dont mean that in a mean way I am just curious why)
Iron (II) oxide is composed of iron with an oxidation number of +2 (shown by the II after iron) and an oxygen that has an oxidation number of -2 (oxygen almost always has an oxidation state of -2). Since the anion and cation both have a charge of +or- 2, they bond with each other with a 1 to 1 ratio and the formula should be FeO
I hope this helps. Let me know if anything is unclear.
