Why is the chemical formula for water H2O and for sodium chloride NaCl why not ho2 and NaCl2?
the chemical formula for water is H2O becoz it has the combination of both oxygen & hydrogen molecules…if the oxygen & hydrogen would become joined in certain measurements it should be possible for producing a water…
Why the chemical formula of water is H2O not ho2?
Selina – Chemistry – Class 7 case 1- H2O tells that there are two atoms of hydrogen combined with oxygen. case 2 can’t exist because the oxygen has 6 electrons in its outermost shell and it needs only 2 atoms of 1 valency to combine with it. so two hydrogens come in giving us H20 not H02.
What happens when NaCl react with h2o?
Ans: When salt is diluted with water then a mixture of ions like Na⁺, Cl⁻, H⁺ and OH⁻ ions will be produced in the salt solution. They may combine to form different products based on affinity.
Is H20 and HO2 same?
In H2O 2 hydrogen atoms and 1 Oxygen atom is present. But In HO2 1 hydrogen atom and 2 Oxygen atoms are present. H2O means water. But HO2 means hydroperoxyl radical.
What is the chemical formula of H20?
H₂O
Water/Formula
Why will the formula for sodium chloride always be NaCl regardless of how it is formed?
Sodium chloride is formed when sodium atoms interact with chlorine atoms. When this occurs, sodium will donate an electron (which is a negatively-charged particle) to chlorine. The chemical formula for sodium chloride is NaCl, which means that for every sodium atom present, there is exactly one chloride atom.
When NaCl dissolves in h20 The reaction can be?
Explanation: Dissolving sodium chloride in water is a chemical change forming a solution of sodium and chloride ions. This solution is an electrolyte (can conduct electricity) because the sodium and chloride ions dissociate due to the polar nature of water.
When NaCl dissolves in water what is the force of attraction between Na and H2O?
When NaCl dissolves in water, aqueous Na+ and Cl- ions result. The force of attraction that exists between Na+ and H2O is called an ion-dipole interaction.
What happens when H2O and NaCl are added to each other?
This is a type of reaction which gives NaCl (aq) that is, it is aqueous solution when H2O is added to NaCl that is Sodium Chloride.. It’s called the ‘Chlor-alkali process’. Electric current is passed through brine and water to get sodium chloride, chlorine and hydrogen.
What happens when sodium chloride reacts with water?
Sodium chloride is react with water molecule to form the products are called sodium hydroxide and Hydrochloric acid. There are no reactions but simply the quantity of NaCl that can be dissolved in the H2O, dissociates almost completely in the cation Na+ and the anion Cl–. The salt that will not dissolved remain a solid.
What type of salt does not dissolve in H2O?
The salt that will not dissolved remain a solid. NaCl is a stable neutral salt; an ionic compound. H2O (i.e. water) is a polar solvent. Adding them together will result in salt solution (i.e. salt water).
What is the meaning of Na+(aq) and NaCl –(AQ)?
This surrounding of sodium and chloride ions by water molecules is called hydration. Therefore, when we write Na +(aq) or Cl –(aq) the symbol ( aq, aqueous) usually means that each ion is attracted to and surrounded by several water molecules.
