Answer;
-Copper (Cu)
Explanation;
-While all metals can conduct electricity, certain metals are more commonly used due to being highly conductive. The most common example is Copper. It is highly conductive which is why it is has been used in electrical wiring.
-Copper is used for electrical wiring because it is a good conductor of electricity. Metal particles are held together by strong metallic bonds, which is why they have high melting and boiling points. The free electrons in metals can move through the metal, allowing metals to conduct electricity.
Answer:
CuO + H₂SO₄ ⟶ CuSO₄ + H₂O
Explanation:
The most likely reaction is a <em>double displacement</em>, in which Cu and H trade partners.
This gives
CuO + H₂SO₄ ⟶ CuSO₄ + H₂O
The equation is already balanced, so no further work is necessary.
Answer:
Elements in the same group of the periodic table have the same number of valence electrons. These are the electrons in their outer energy level that can be involved in chemical reactions. ... All the elements in group 1 have just one valence electron. This makes them very reactive.
