Answer:
option A = S(s) + O₂(g) → SO₂ (s)
Explanation:
Chemical equation:
S(s) + O₂(g) → SO₂ (s)
when sulfur burned in the presence of oxygen it produce sulfur dioxide. The sulfur dioxide can further react with oxygen to produce sulfur trioxide and then react with water to form sulfuric acid.
Uses of sulfur dioxde:
It is used as a solvent and reagent in laboratory.
Sulfur dioxide is used to produce sulfuric acid.
It is used as a disinfectant
It is also used as a reducing agent.
It is used to preserve the dry food.
Answer:
C. Fe will stay positive and increase in magnitude.
Explanation:
Coulomb's law states that the force of attraction of repulsion between two charged particles is directly proportional to the magnitude of their charges and inversely proportional to the square of the distance of separation between them.
This means that if the size of the charges are large, the force acting on them will be large as well. Also if the distance between the two charges increases the force decreases. However, the force increases when the distance of separation decreases.
Like charges repel, therefore, two negative charges brought together will repel each other, and the distance between the two charges decreases, the force will increase in magnitude. Forces of repulsion are considered positive, therefore, the force, Fe, will stay positive and increase in magnitude.
There are 3 isotopes of hydrogen
The department of the FBI in which Natalia is most likely to work for is Questioned Documents Unit (QDU).
<h3>What is Questioned Documents Unit?</h3>
This is a unit of the FBI which is specialized in conducting forensic examinations on evidence collected during an investigation.
