Answer:
Cu2O + H2SO4 ——> CuSO4 + Cu + H2O
Cu2O is oxidized and reduced. It lost an electron in CuSO4 for the 2+ charge, but it gained an electron in Cu to go from the 1+ charge to a neutral charge. This is dismutation (aka disproportionation)
Explanation:
The answer is F, or Fluorine.
Because of Fluorine's high reactivity, it is never found in nature.
The answer is F.
Answer:
1. Cations are positively charged and have less electrons than protons.
2. Anions are negatively charged and have more electrons than protons.
3. Columns on the periodic table are known as groups.
4. The elements in the first group are called alkalis metals and have one valence electron.
Explanation:
I think you were doing it right. Just find something in your kitchen and google the chemical formula. And from that you can see the elements in it. For example:
Salt, NaCl, Sodium and Chlorine.
Baking Soda, NaHCO3, Sodium, Hydrogen, Carbon and Oxygen.
Vinegar, CH3COOH, Carbon, Hydrogen and Oxygen
