Answer:
The coefficient of O2 in the correctly balanced equation is 9
Explanation:
As2S3 + 02 -------------> As2O3 + SO2
Balancing this reaction, we have;
2As2S3 + 9O2 -----------> 2As2O3 + 6SO2
9 moles of oxygen will be the correct coefficient and number of moles for the reaction to be correctly balanced.
In the balanced reaction, we have 4 moles of As; 6 moles of S and 18 moles of O on both sides of the equation.
Answer:
Lead atoms have 82 electrons and the shell structure is 2.8. 18.32. 18.4.
Explanation:
The ground state electron configuration of ground state gaseous neutral lead is [Xe].
Explanation:
Nuclear energy is found in the nucleus of an atom holding nuclear materials in place.
When a nuclear decay or fusion occurs, the energy is released.
- Most times, the nuclear energy is transformed into heat energy.
- The heat energy is used to do other forms of work that converts energy from one form to another.
- It can be converted to mechanical energy when water is boiled and used to drive turbines.
- It can be used in heating chambers.
- this and many more can lead to energy transformation
