We know that,
acceleration (a) = final velocity(V)-initial velocity(U)/ Time taken(T)
Answer:
Sulfur dioxide
Explanation:
Sulfur dioxide (SO₂) is a colorless gas, which comes from burning fossil fuels like burning coal, oil and diesel from vehicles. This gas is also released into the environment through volcanic eruptions.
Sulfur dioxide is considered one of the worst air pollutants, mainly because it accumulates in droplets in the air and also because it reacts with other compounds in the atmosphere, forming particulate materials.
This gas is a major contributor to the warming of the planet. Its presence in acid rain (which makes it return from the atmosphere to the earth) is dangerous for plants and animals, in addition to corroding some materials and affecting monuments, buildings, statues.
Acid rain generated by SO₂ and other compounds can lower the pH of lakes and reduce fish populations. In plants, vegetables and flowers, it compromises production and growth.
In humans, sulfur dioxide can cause acute and chronic health effects, especially on the respiratory system, in addition to aggravating cardiovascular problems due to the simultaneous presence of SO₂ and particles in the atmosphere.
Answer:
1) They are directly proportional
2) They are also inversely proportional
Explanation:
1. as the temperature increases, the pressure also increases. and vice versa.
2. however, as the volume increases, the pressure decreases. and if the volume decreases, the pressure increases.
The answer is N2 + 3H2 yields 2NH3. The oxidation-reduction reaction means that there is electrons transfer during the reaction which means that the valence changed.
