Answer:
K = [H₂]² [ O₂] / [H₂O]²
Explanation:
The equilibrium constant of any reaction can be written as,
K = [product]/ [reactant]
For given reaction:
Chemical equation:
2H₂O → 2H₂ + O₂
equilibrium constant:
K = [H₂] [ O₂] / [H₂O]
In stoichiometric calculations, we will put the coefficient of balanced equation in given equilibrium constant equation.
K = [H₂]² [ O₂] / [H₂O]²
An ionic bond is formed by the transfer of electrons from one atom to the other. It is usually formed between a metal + non-metal.
A covalent bond is formed by sharing of electrons between two atoms. It is formed between two nonmetals. A polar covalent bond is formed between 2 non-metals which differ in their electronegativities. In contrast, in a non-polar covalent interaction the two atoms could either be the same or have very close electronegativities.
1) P and I : Both non-metals with different electronegativities= Polar Covalent
2) Fe and O: Metal + non-metal = Ionic
3) S and Cl: Both non-metals with different electronegativities= Polar Covalent
4) S and S: Both non-metals and the same atoms = Non-polar Covalent
5) Br and Br: Both non-metals and the same atoms = Non-polar Covalent
6) O and Cl: Both non-metals with different electronegativities= Polar Covalent
7) Be and Cl: Metal + non-metal = Ionic
8) Al and N: Metal + non-metal = Ionic
Answer:
Elements only contain one type of atoms while compounds contain two or more types of atoms.
Explanation:
An example of an element is sodium --> Na (only Na atoms)
An example of a compound can be water --> H2O (contain H and O atoms)
*But the particles within a compound are all the same.
Answer:
Calcium is an element With an atomic number of 20. The most common atoms of calcium have a mass number of 40. But some Atoms of calcium have a mass number of 44
What is meant but the tears atomic number
