The benzene molecule has the molecular formula C6H6
.
Sometimes it is represented as a molecule with three doble bonds and three single bonds. But that does not count for the fact that experimentally all the bonds are equal: same length and same strength.
The six carbon bonds are equal because there is not preference for the valence electrons to attach to one or othe neighbor carbon, so at the electrons delocalize inside the molecules and form a uniform cloud around the six carbon atoms.
This is the effect named resonance and thas is why the molecule of benzene instead of being represented with some three single bonds and three doble bonds is represented with a circle (a ring) inside the molecule which represents an intermediate kind of bond shares by all the carbon atoms.
This structure was discovered (literally dreames as some texts tell) by Kekulé.
Answer:
Boom
Explanation:
The bomb is big and it goes boom and it also creates nuclear fragments everywhere
Explanation:
According to the law of conservation of mass, mass can neither be created nor it can be destroyed. But it can be simply transformed from one form to another.
Therefore, when 
is added to NaCl then the compound formed will have same mass as that of reactants.
Total mass of reactants is (169.87 + 58.44) g/mol = 228.31 g/mol
Total mass of products is (143.32 + 84.99) g/mol = 228.31 g/mol
Thus, we can conclude that mass of the new mixture will stay the same.
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.

Answer:
elliptical galaxy
Explanation
:The combination of the two galaxies then forms what appears to be an elliptical galaxy as the arms begin to disappear. The merger of gasses creates new stars, and the new shape becomes more elliptical, globular, or sometimes irregular.
