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:
Answer: Option (a) is the correct answer.
Explanation:
Non-metals are the species which in order to complete their octet readily gain an electron.
For example, fluorine is a non-metal with atomic number 9 and its electronic distribution is 2, 7.
Hence, to attain stability it readily accepts an electron from a donor atom.
Some characteristics of non-metals are as follows.
Non-metals do not conduct electricity.
Non-metals are brittle in nature and they have a rough surface.
Non-metals are not malleable or ductile.
Thus, we can conclude that non-metals do not conduct electricity is a characteristic of non-metals.
Answer: yes
When the concentration of all the reactants increases then the rate of reaction increases. When the concentration decreases then the rate of reaction decreases.
This all because more molecules or ions form new compounds. Or losses.
The Chemical reactivity of metals varies with your eletropositividade, so the more eletropositivo is the most reactive element is metal. The most reactive metals are those that have great tendency to lose electrons and therefore form positive ions with more ease.
