Answer:
Calcium is more reactive.
Explanation:
It is higher in the reactivity series, and contains more energy levels.
Answer:
Copper is typically a solid and has a coppery, bronzy color. It is a metal and has a relatively high melting point. It has a strong luster and can conduct electricity.
Answer:
Have some attraction towards each other
Explanation:
Gases deviate from the ideal gas behavior because their molecules have forces of attraction between them. At high pressure, the molecules of gases are very close to each other so the molecular interactions start operating and these molecules do not strike the walls of the container with full impact.
Hope this helps :-)

The Ti 2+ ions is represented by electron configuration (Ar)3d2. Titanium is in atomic number 22 and its electronic configuration is (Ar)3d2 4s2. Titanium loss two electron that is 4s2 electrons hence the electronic configuration ( Ar)3d2. 4s2 is the valence electron hence it the one which is lost to form Ti2+
It is a combustion reaction because when methane burns with oxyzen it produces carbon dioxide,water and heat and light.
