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:
Natural Gas
Explanation:
Let's remember: A non-renewable resource means a source that is used faster than it can be replaced. The sun will always be there for solar energy. Wind will always be there for wind energy. Hydropower isn't always there, but it is a semi-renewable source because it is replenished relatively fast. We are left with natural gas, and it takes millions of years to replace.
Metals have a low electron affinity- a less likely chance to gain electrons because they want to give up their valence electrons rather than gain electrons, which require more energy than necessary.
C. The number of moles of H in 0.109 mole of N₂H₄ is 0.436 mole
D. The number of moles of H in 34 moles of C₁₀H₂₂ is 748 moles
<h3>C. How to determine the number of mole of H in 0.109 mole of N₂H₄</h3>
1 mole of N₂H₄ contains 4 moles of H
Therefore,
0.109 mole of N₂H₄ will contain = 0.109 × 4 = 0.436 mole of H
<h3>D. How to determine the number of mole of H in 34 mole of C₁₀H₂₂</h3>
1 mole of C₁₀H₂₂ contains 22 moles of H
Therefore,
34 mole of C₁₀H₂₂ will contain = 34 × 22 = 748 mole of H
