Answer:
High levels of nitrogen dioxide are also harmful to vegetation—damaging foliage, decreasing growth or reducing crop yields. Nitrogen dioxide can fade and discolour furnishings and fabrics, reduce visibility, and react with surfaces.
1-We could use low-nitrogen fuels
2- We could also modify combustion conditions to generate less NOx. Flue gas treatment techniques, such as selective cata- lytic reduction (SCR) processes, can remove NOx
Answer:
Explanation:
Salt water intrusion can cause the <u><em>fresh</em></u> water in wells to become contaminated with<u><em> salt</em></u>water.
Hydrocarbons are chains of C and H. C and H are held together by covalent bonds.
hydrocarbons are of three main types
alkanes - only single bonds between C atoms
alkenes - double bonds between C atoms present
alkynes - triples bonds between C atoms present
saturated hydrocarbons definition is when there are only single bonds present
from the given compounds
propane - only single bonds
propene - double bond
propyne - triple bond
propanal - double bond between C and O
only compound with single bonds is propane
answer is propane
Answer:
- <u>Compressibility, expandibility, and density, are the most conspicuous properties of the gases explained by </u><em><u>the assumption that most of the volume in a gas is empty space.</u></em>
Explanation:
One of the assumptions of the kinetic molecular theory is that the gas particles are way smaller than the separtion between them and, in consequence, most of the volume in a gas is empty space.
This condition (that most of the volume in a gas is empty space) explains why the gases can be easily compressed: since there are vast unoccupied spaces when the pressure is increased, the particles can approach each other with which the total volume of the gas decreases.
Expandibility, the property of expanding, is the ability that gases have to occupy the entire space of the container in which they are located. The particles then will get separated leaving most of the space empty.
The fact that most of the volume in a gas is empty space means that the volume for a certain amount of particles is much larger than the volume that the same number of particles in a solid will occupy, driving to much lower densities.
