Given unbalanced chemical reaction:
?D₂(g)+ ?O₂(g) →?D₂O(l)
Balancing the given chemical equation using whole-number coefficients:
2D₂(g)+ O₂(g) →2D₂O(l)
Therefore, the coefficients in order separated by commas are:
2, 1, 2
Antoine Lavoisier proved that oxygen is required for material to burn. Without oxygen, the fire goes out which is easily testable.
32g of oxygen is required to burn 4g of hydrogen.
Define molecular mass.
A specific molecule's mass is expressed in daltons and is known as the molecular mass (m) (Da or u). Due to the varying isotopes of an element that they contain, multiple molecules of the same substance can have distinct molecular weights.
The total atomic mass of every atom in a molecule, calculated using a scale with hydrogen, carbon, nitrogen, and oxygen having atomic masses of 1, 12, 14, and 16, respectively. For instance, water has a molecular mass of 18 (2 + 16), which consists of two hydrogen atoms and one oxygen atom. known also as molecular weight.
In ,2H2+O2-----> 2H2O
H 2 molecules have a mass of 2 g/mol.
The molecular weight of oxygen is 32 g/mol.
When the chemical equation is balanced,
To totally react, 32 g of oxygen are needed for every 22=4 g of hydrogen.
