Calcium oxide is definitely a base forming oxide, only nonmetals can have acidic oxides, though some other metal (amphoteric) oxides are also (mainly weak) acid forming oxides.

An oxide ion is oxidized to an oxygen atom by what?
An oxygen atom can only be oxidized by some element with an equal or higher electronegativity. So, oxygen can be oxidized by fluorine (e.g., OF2) or by another oxygen atom (e.g., O2).
What happens to the outer shell of a calcium atom when it reacts with an oxygen atom?
the outer cell will burn up leaving calcium-oxide
When calcium metal reacts with oxygen gas in the air to form calcium oxide suppose you react 6.55 mol calcium with 4.00 mol oxygen now determine the number of moles of calcium oxide produced?
Calcium contains only one atom per molecule, while oxygen contains two. The usual reaction product from a reaction between calcium and oxygen has the formula CaO and therefore contains one atom of each element per molecule. 4 moles of oxygen provides 8 moles of oxygen atoms, so that under the conditions given, calcium is the limiting reactant, and 6.55 moles of calcium oxide will be formed.
What happens to the outer shell electrons of a calcium when it reacts with a oxygen atoms?
The two outer shell electrons of a calcium atom are donated to an oxygen atom, forming calcium cations and oxygen anions that together constitute the salt compound calcium oxide.
How many moles of calcium oxide are produced when 36.5 grams of calcium reacts completely with oxygen gas?
2Ca + O2 --> 2CaO The molar mass of Calcium is 40g/mol. 36.5g/40g gives you 0.9125 moles of Calcium. The moles of calcium are equivalent to the moles of Calcium oxide. The answer is 0.9125 moles of calcium oxide. Correct me if I am wrong.
What compound is produced when calcium reacts with oxygen?
calcium oxide, CaO
What salt is formed when calcium oxide reacts with sulphuric acid?
calcium sulfate and water
What is the gas that reacts with calcium and magnesium when they burn?
Hydrogen gas is released when calcium and water react.
What compounds are formed when magnesium reacts with oxygen?
Magnesium reacts with oxygen to form magnesium oxide (MgO).
What is the compound formed when Calcium oxide reacts with water?
calcium hydroxide and hydrogen gas
An oxide ion is oxidized to an oxygen atom by what?
An oxygen atom can only be oxidized by some element with an equal or higher electronegativity. So, oxygen can be oxidized by fluorine (e.g., OF2) or by another oxygen atom (e.g., O2).
What happens when calcium and oxygen react?
It turns a bright red color and it does not spread. If you take a little bit of calcium and put in a bowl and light it up, it will crete a small fire in the bowl but it will not burn it.
Calcium metal reacts with oxygen gas to produce solid calcium oxide?
Correct 2 Ca + O2 ------> 2CaO
What happens to the outer shell of a calcium atom when it reacts with an oxygen atom?
the outer cell will burn up leaving calcium-oxide
What iron reacts with oxygen what new substance is formed?
rust, iron oxide or dioxide
When calcium is burned calcium oxide is formed whats the word equation for this and reaction type?
I'm sure it's an oxidation reaction. calcium + oxygen gas ---> Calcium oxide
When titanium reacts with oxygen is the oxide formed a acid or a base?
