Part e
the population census of a city shows that its population has grown in the last decade.
this growth has surpassed the city's ability to provide sufficient water to its people. the
city is located about 10 miles from the ocean and has a dry climate. based on your
research and the list of criteria and constraints from part a, suggest a technology to use
in this city. defend your choice with a valid explanation.

Answers

Hydroelectricity is the technology whose growth has surpassed the city's ability to provide sufficient water to its people.

What is technology?

Technology is the process of fusing science and the application of skills in scientific industries.

The population can use the waves even the tides of the ocean's water to create electricity which is reliable.

Of course in the beginning it will be expensive but the result will be effective and useful.

The area having a dry climate could be because of the winds that blow precipitating clouds away but they can have a stable climate by planting more trees where rain can be processed within the geographical location.

Finally, the problem of water supply can be fixed by installing water pipes to transport water to the community but in the process, water can be filtered or cleaned to prevent some diseases and social issues/calamities.

Hence, hydroelectricity is the technology whose growth has surpassed the city's ability to provide sufficient water to its people.

Answers

Answer:

Less

Explanation:

The hydronium from the HCl is used to neutralize the bicarbonate in the baking soda. The hydronium is the acid and the bicarbonate ion is the base while the sodium and chloride ions are pH-neutral. Since theres a 1:1 mole ratio of hydronium to HCl and bicarbonate to sodium bicarbonate, it would require less HCl to neutralize a less concentration baking soda solution.

Answers

In order to dissolve a chemical sample in a recrystallization solvent, add the room-temperature solvent just until it covers the sample in an Erlenmeyer flask on a hot plate.

What is recrystallization solvent?

Recrystallization involves dissolving the material to be purified (the solute) in an appropriate hot solvent.

Recrystallization, also known as fractional crystallization, is a procedure for purifying an impure compound in a solvent.

The method of purification is based on the principle that the solubility of most solids increases with increased temperature. Small crystals may trap impurities.

Thus, in order to dissolve a chemical sample in a recrystallization solvent, add the room-temperature solvent just until it covers the sample in an Erlenmeyer flask on a hot plate. Turn on the heat, starting at a low setting and increasing gradually.

Ideal Gas Law Question How many moles of C2H4O are in a 58.953 L container at 467.81kPa and 446.11 °C?

Answers

The number of moles of gas in the container would be 4.62 moles

Ideal gas law

According to the ideal gas law:

  PV = nRT, where P = pressure, V, volume, n = mole number, and R = constant = 8.31

In this case, V = 58.953 L, P 467.81 kPa, and T = 719.11 K

Making n the subject:

   n = PV/RT = 58.953 x 467.81/8.31 x 719.11 = 4.62 moles

Calculate the speed of light in an unknown substance whose index of refraction is 1.65. Would you expect the light to bend toward the normal or away from the normal when it passes from air into the substance?

Answers

(a) The speed of light in the unknown substance is determined 1.82 x 10⁸ m/s.

(b) The light will bend away from the normal since speed of light in air is not equal to speed of light in the substance.

What is the speed of light?

The speed of light passing from air into the substance is calculated as follows;

refractive index = speed of light in air / speed of light in the substance

speed of light in the substance = speed of light in air/refractive index

speed of light in the substance = (3 x 10⁸) / (1.65)

speed of light in the substance = 1.82 x 10⁸ m/s

Thus, the light will bend away from the normal since speed of light in air is not equal to speed of light in the substance.
