Answer:
It was important to establish the clean air act to create a regulation that makes any activities pollute the air illegal
Explanation:
4.37*v=2.33*0.755
V=1.76/4.37
V=0.4025 l

Answer:
Some common compounds in our daily lives:
Water, H2O. We need this for survival, because it serves a lot of functions in our body, such as being a medium for chemical reactions in our cells.
Carbon Dioxide, CO2. It is one of the components of air, our body also produces CO2 during respiration.
Sodium chloride, NaCl. Table salt is mostly made of sodium chloride. It is also found dissolved in sea water.
Methane, C2H4. This is a common fuel for generating electricity. It can also be found (small amounts) in air.
Nitrogen Dioxide, NO2. It can also be found in air, and it is one of the common air pollutants brought by burning of fossil fuels.
Answer: option D) energy was absorbed and entropy increased.
Explanation:
1) Given balanced equation:
2H₂O (l) + 571.6 kJ → 2 H₂ (g) + O₂(g).
2) Being the energy placed on the side of the reactants means that the energy is used (consumed or absorbed). This is an endothermic reaction.
So, the first part is that energy was absorbed.
3) As for the entropy, it is a measure of the disorder or radomness of the system.
Since, two molecules of liquid water were transformed into three molecules of gas, i.e. more molecules and more kinetic energy, therefore the new state has a greater degree of radomness, is more disordered, and you conclude that the entropy increased.
With that, you have shown that the right option is D) energy was absorbed and increased.
