How many atoms in molecule 2CaCO3?
2Ca: 2, C: 1, O3: 3, 2 + 1 + 3 = 6
2Ca 02-2CaO what is being oxidized?
In this reaction, calcium is being oxidised. In 2Ca, its oxidaton state is 0 and after the reaction it is increased to +2 which forms a bong with oxygen ion. Since its oxidation state is increased from 0 to +2, it is being oxidised. Or you can look at it in another different manner. Calcium gains oxygen in the reaction thus it is being oxidised. It also loses electrons to form an ion which reacts with oxygen ion. Any substance is being oxidised when it oxidation state increases, gains oxygen atoms, loses hydrogen atoms or loses electrons.
How many moles of the product form when 0.016 mol of O2 completely reacts 2Ca plus O2 ----- 2CaO?
.183mol CaO Ca is your limiting reactant, O2 is your excess reactant. thus 7.34g Ca = .183mol Ca, since the balanced reaction is 2Ca + 1 O2 -> 2 CaO, 1 mol Ca = 1 mol Cao and .183mol CaO is produced.
What is the equation of oxidation of calcium?
2Ca + O2 = 2 CaO
What is the symbol equation for calcium oxide?
2Ca + O2 ------> 2CaO

What is the balanced equation of calcium and oxygen to produce calcium oxide?
2Ca+O2---->2CaO
What is the balanced symbol equation for calcium and oxygen gas with state symbols?
2Ca(s) + O2(g) ----> 2CaO(s)
How many atoms are in calcium hydroxide?
Calcium hydroxide = Ca(OH)2 Ca = 1 atom OH = 2 atoms
What is 3ac plus 2ca?
3ac + 2ca = 3ac + 2ac = (3 + 2)(ac) = 5ac

What is the balanced equation for calcium and oxygen gas?
Ca(ClO3)2 --> CaCl2 + 3O2 is the equation for calcium chlorate to calcium chloride + oxygen gas.
What would be produced when calcium is heated in air?
Calcium most likely will react with the oxygen in the air. 2Ca(s) + O2(g) -->2CaO(s). It would form solid calcium oxide.
What is the symbol equation for calcium oxide?
2Ca + O2 ------> 2CaO
What is the equation of oxidation of calcium?
2Ca + O2 = 2 CaO
What is the chemical formula for calcium ethanoate?
Formula: (CH3COO)2Ca
