Calcium hydroxide = Ca(OH)2
Ca = 1 atom
OH = 2 atoms
There are three elements present - Calcium, Hydrogen and Oxygen. The answer lies in being able to draw the molecular formula Ca(OH)2, which contains all necessary information to solve the problem as it shows the letters for each elemet (Ca = calcium, O = Oxygen, H = Hydrogen).
Ca(OH)2, pronounced C-A-O-H-twice, has three atoms 5 atoms in each molecule.
Ca5(PO4)3(OH)
5 Calcium
3 Phosphorous
13 Oxygen
1 Hydrogen
Calcium hydroxide = Ca(OH)2
Ca = 1 atom
OH = 2 atoms × 2 = 4 atoms
Ca(OH)2 = 5 atoms

calcium hydroxide
A compound is a mixture of elements. As the name implies, CH (or calcium hydroxide) is made up of calcium and hydrogen. Calcium and Hydrogen are elements. Thus, calcium hydroxide is a compound.
Five(5) hydrogen atoms
The chemical formula of Calcium hydroxide is Ca(OH)2
The formula unit for calcium nitride is Ca3N2. That would be 3 atoms of calcium and 2 atoms of nitrogen, for a total of 5 atoms in a formula unit.
Calcium is bivalent and hydroxide is monovalent, so its formula is Ca(OH)2 => 5 atoms
There is 1 Ca atom in calcium hydroxide. The formula is Ca(OH)2
There is 1 Ca atom in calcium hydroxide. The formula is Ca(OH)2
Calcium Hydroxide is Ca(OH)2 and potassium phosphate is K3PO4. So calcium hydroxide has 5 atoms and potassium phosphate has 8 atoms. So potassium phosphate has the most atoms.
The answer is 0,068 mol (for O not for O2).
The hydroxide anions in calcium hydroxide have covalent bonding between oxygen and hydrogen atoms, and these anions are ionically bonded to calcium cations to form the complete compound.
The hydroxide anions in calcium hydroxide have covalent bonding between oxygen and hydrogen atoms, and these anions are ionically bonded to calcium cations to form the complete compound.
Because the atoms would be in the wrong order.
26.3 g of calcium hydroxide contain 2,054 molecules.
there are 20 atoms in calcium
NH4OH has 7 atoms
Barium hydroxide - Ba(OH)2: 5 atoms.
