1. An ionic bond is an attraction between oppositely charged ions. A covalent bond is sharing of electrons between atoms.
2. A bond between two atoms
3. covalent bond
4. They have different properties because the arrangement of atoms is different.
5. Mutual attraction between the nuclei and electrons in two different atoms
Answer:
In redox reactions, electrons are transferred from one species to another. If the reaction is spontaneous, energy is released, which can then be used to do useful work. To harness this energy, the reaction must be split into two separate half reactions: the oxidation and reduction reactions.
The balanced chemical equation is:
2H2 + O2 ---> 2H2O
We are given the amount of the product produced from the reaction. This will be the starting point for the calculations.
355 g H2O ( 1 mol H2O/ 18.02 g H2O) ( 1 mol O2 / 2 mol H2O ) ( 32 g O2 / 1 mol O2 ) = 315.205 g O2
