What is ionic equation?
Ionic equation is defined as a chemical equation which represents electrolytes in aqueous solutions and are expressed as dissociated ions. Ions present in aqueous solutions are stabilized by ion dipole interactions with the water molecules which are present.
An ionic equation can be written for any electrolyte which dissociates and reacts with the polar solvent. In a balanced ionic equation , number and type of atoms on each sides of reaction arrow are same. Even the net charge on both sides of the arrow is same.
Strong acids and bases exist as dissociated ions present in the solution and are written in forms of ions in ionic equation.Weak acids and bases do not dissociate completely and hence are written in the form of molecular formula.

2CO + O2 → 2CO2
Answers
the ratio between CO and CO2 is 2 : 2 ( or 1 : 1) so we would get 0.357 mole of CO2 ( 100% yield)
mass CO2 = 0.357 mol x 44.0098 g/mol = 15.7 g ( theoretical yield)
% yield = 12.8 x 100 / 15.7 = 81.5
Hope this helps.

The total number of moles of atoms in Pb(C₂H₃O₂)₂ is 66.242 x 10²³ atoms.
What is mole?
The total number of moles of atoms, use Avogadro's number, which is approximately 6.022 x 10²³ particles (atoms or molecules) per mole.
The molecular formula of Pb(C₂H₃O₂)₂ has one lead (Pb) atom, two carbon (C) atoms, four hydrogen (H) atoms, and four oxygen (O) atoms in one molecule of the compound.
So, the total number of moles of atoms in one mole of Pb(C₂H₃O₂)₂ can be calculated as follows:
1 Pb atom x (1 mole Pb / 1 mole Pb(C₂H₃O₂)₂ x (6.022 x 10²³ atoms / 1 mole Pb) = 6.022 x 10²³ Pb atoms
2 C atoms x (1 mole C / 1 molePb(C₂H₃O₂)₂ x (6.022 x 10²³ atoms / 1 mole C) = 12.044 x 10²³ C atoms
4 H atoms x (1 mole H / 1 mole Pb(C₂H₃O₂)₂ x (6.022 x 10²³ atoms / 1 mole H) = 24.088 x 10²³ H atoms
4 O atoms x (1 mole O / 1 mole Pb(C₂H₃O₂)₂ x (6.022 x 10²³ atoms / 1 mole O) = 24.088 x 1023 O atoms.
6.022 x 10²³ Pb atoms + 12.044 x 10² C atoms + 24.088 x 10²³ H atoms + 24.088 x 10²³ O atoms = 66.242 x 10²³ atoms
Therefore, there are approximately 66.242 x 10²³ atoms in one mole of Pb(C₂H₃O₂)₂.

hydrogen atom forms covalent bonds with more than one atom.
hydrogen atom of a polarized molecule bonds with an electronegative atom
hydrogen atoms form an ionic bond with one other atom
Answers
Answer: hydrogen atom of a polarized molecule bonds with an electro negative atom.
Explanation:
Hydrogen bonds are special type of dipole dipole forces which are formed when hydrogen bonds with an electro negative element. Hydrogen bonds are strongest type of bonds .Example: Bond between Oxygen of one water molecule to the hydrogen of another water molecule as shown in the image below.
Covalent bonds are formed by sharing of electrons among non metals.
Ionic bond is formed by transfer of electrons between metals and non metals.
Answer:
No because hydrogen can only form these bonds with highly electronegative atoms.
Explanation:
