What is the word equation for 2H2 O2 2H2O?
What is the word equation for 2H2 O2 2H2O?
The actual reaction to make water is a bit more complicated: 2H2 + O2 = 2H2O + Energy. In English, the equation says: To produce two molecules of water (H2O), two molecules of diatomic hydrogen (H2) must be combined with one molecule of diatomic oxygen (O2).
How do you write H2O?
Water (chemical formula: H2O) is a transparent fluid which forms the world’s streams, lakes, oceans and rain, and is the major constituent of the fluids of organisms. As a chemical compound, a water molecule contains one oxygen and two hydrogen atoms that are connected by covalent bonds.
What is H2O full name?
H2O is the molecular formula of water, also called Dihydrogen monoxide. H2O symbolises two hydrogen atoms and one oxygen atom.
What is the O in H2O?

Is water ionic or covalent?
Water is a Polar Covalent Molecule Water (H2O), like hydrogen fluoride (HF), is a polar covalent molecule.
How do you know if it is ionic or covalent?
Classifying compounds as ionic or covalent
- If a compound is made from a metal and a non-metal, its bonding will be ionic.
- If a compound is made from two non-metals, its bonding will be covalent.
Is NaCl covalent or ionic?
For example, sodium (Na), a metal, and chloride (Cl), a nonmetal, form an ionic bond to make NaCl. In a covalent bond, the atoms bond by sharing electrons. Covalent bonds usually occur between nonmetals.
Is Salt a covalent or ionic bond?
Salt is made up of sodium and chloride and is ionically bonded. Sugar, on the other hand, is composed of carbon, oxygen, and hydrogen and has covalent bonds. A salt molecule is made up of one sodium atom and one chlorine atom. For salt to be made, the sodium atom must lose an electron and become a sodium ion.
Is NaCl ionic polar or nonpolar?
Sodium Chloride (NaCl) which is an ionic compound acts as a polar molecule. Usually, the large difference in electronegativities in sodium and chlorine makes their bond polar.
Why is NaCl ionic?
Sodium chloride or NaCl is an ionic compounds made up of sodium (Na) and Chloride (Cl) ions. An atom can lose an electron and attain a positive charge to become a cation. Hence sodium chloride is the ionic compound made by electron exchange between two different ions. Hope this helps.
