Which best explains why nanofiltration is an important new technology?
A. It can be used to help regions that have a short supply of usable water.
B. It can be used as an energy source to produce electricity in regions with limited coal.
C. It recycles wastewater to be reused for geothermal energy.
D. It collects solar energy to generate electrical power.
Explanation:
Our Direct Nanofiltration (dNF) membranes offer the unique combination of a low fouling hollow fiber configuration with the ability to remove organics and salinity (hardness) from water in one simple step. Other than a strainer, no further pre-treatment is required. We manufacture our membranes with a patented layer-by-layer process, where multiple nano-scale layers are deposited on a membrane support. This method enables very precise and controlled rejection and flux properties of the membrane. A unique solution for troubled water.

Explanation:
Zingerone, one of the flavor molecules in ginger,
contains only C, H, and O. Combustion of 10.0 g
of zingerone produces 24.91 g of CO2 and
6.522 g of H20. Determine the molar mass of the
compound if it is between 150.0 and 220.0 g/
mol. Provide an answer to four significant
figures.
The molecular formula of the compound is C12H15O3 hence the molar mass of the compound is 207 g/mol.
We need to obtain the number of moles of carbon, hydrogen and oxygen in the compound;
Carbon = 24.91 g/44g/mol × 1 mole of carbon = 0.566 moles
Mass of carbon = 0.566 moles × 12 g/mol = 6.792 g
Number of moles of hydrogen = 6.522 g/18 g/mol × 2 moles = 0.725 moles
Mass of hydrogen = 0.725 moles × 1 g/mol = 0.725 g
Mass of oxygen = 10 - (6.792 g + 0.725 g) = 2.483 g
Number of moles of oxygen = 2.483 g/16 g/mol = 0.155 moles
Now we must divide through by the lowest number of moles;
C - 0.566/0.155 H - 0.725/0.155 O - 0.155/0.155
C - 4 H - 5 O - 1
The simplest formula is C4H5O Recall that the molar mass of the compound lies between 150.0 and 220.0 g/mol
4(12) + 5(1) + 16 = 69
Hence; n = 3 and the molecular formula of the compound is C12H15O3
The molar mass of the compound is; 12(12) + 15(1) + 3(16) = 207 g/mol

Usain Bolt went from 0.0 to
11.0m/s in 3.4s. What was his
acceleration?
Answer:
Answer: Change in speed = 11 m/sTime taken = 3.4sHence, acceleration = (11/3.4) m/s² = 3.235 m/s²
Explanation:
(winks and runs off)
Acceleration is 3.235 m/s² when Usain Bolt went from 0.0 to 11.0 m/s in 3.4 seconds.
What is acceleration?
Acceleration is defined as a rate at which the velocity changes with time with respect to both speed and direction.An object is said to be accelerated if it's speeds up r slows down.
Motion along a circle is always accelerated even when speed is constant it's direction is continuously changing.Acceleration is a vector quantity as it has both magnitude as well as direction.The magnitude of acceleration is described by Newton's second law of motion.
Formula of acceleration is change in speed /time.Substituting the given values in the given formula,(11.0-0.0)/3.4=3.235 m/s².
Thus, the acceleration is 3.235 m/s² when Usain Bolt went from 0.0 to 11.0 m/s in 3.4 seconds.

Total atoms=4(2)=8Which best describes the energy change that takes place during deposition?
Heat energy released by the substance
Heat energy is maintained by the substance
Heat energy is slowly gained by the substance
Heat energy is quickly absorbed by the substance
Answer:
heat energy released by the substance
The energy change that takes place during deposition is that heat energy is released by the substance. This statement is true about deposition.
Deposition is a phase transition that occurs when a gas is converted directly to a solid without passing through the liquid state. During deposition, energy is released by the gas particles and absorbed by the surface, resulting in a decrease in the energy of the gas particles and an increase in the energy of the surface particles.As a result, the substance releases heat energy as it changes from a gas state to a solid state.
Therefore, the correct option is:Heat energy released by the substance.

HELP QUICK carbon dioxide makes up less than 1 percent of earths atmosphere, and oxygen makes about about 20 % These percentages are maintained most directly by what
Answer:
respiration and photosynthesis
Explanation:
The percentages of carbon dioxide and oxygen in Earth's atmosphere are maintained most directly by cellular respiration and photosynthesis.
What is photosynthesis?Photosynthesis simply refers to a biological and chemical process through which green plants convert light energy derived from the Sun into chemical energy, so as to make their food while using carbon dioxide (CO₂) and releasing oxygen.
On the other hand, cellular respiration is a series of metabolic reactions that occur in living cells and it involves the use of oxygen that are typically produced by green plants (autotrophs) during photosynthesis.
This ultimately implies that, the percentages of carbon dioxide (1%) and oxygen (20%) that are contained in Earth's atmosphere are maintained most directly by cellular respiration and photosynthesis.
