Answer:
A
Explanation:
The law of conservation of mass states that matter can never be created nor destroyed but can be converted from one form to another.
The law of conservation of energy posits that energy cannot be created nor destroyed but can be converted from one form to another.
These laws are the basic laws of existence. Although the laws have been adjusted, they still form the basic principle behind several scientific laws and are responsible for a whole lot of scientific advancements.
While the first law focuses on matter and the content of matter in a body, the second law basically focuses on energy. The second law serves to support the inter convertibility behind the several forms or types of energy.
For example, to do many useful work at home, it is found that energy is converted from its electric form to say heat in an electric iron to press our clothes.
Also, the first law is a fundamental principle useful in the balancing of our chemical equations.
0 1 2 3
0 and 3 is 3
1 and 2 is 3
Answer:
Sulfur dioxide is a covalent bond because we have two non-metals (Sulfur and Oxygen).
(<em>Sulfur dioxide formula)</em>
It's called Sulfur dioxide but it can be called Sulfurous anhydride and Sulfur (lV) oxide.
Sulfur dioxide can have different reactions:
-
In the presence of oxygen oxidation of sulfur dioxide to sulfur trioxide occurs and the formula is:
The equal is because it's a reversible equation. This reaction is spontaneous.
- The sulfur trioxide reacting with water produces sulfuric acid. The formula is:
- Also the sulfur dioxide reacting with sodium hydroxide produces sodium sulfite and the formula is:
- And finally we have the reduction of sulfur dioxide (it can be in presence of hydrogen sulfide) getting elemental sulfur and water. The formula is:
