Chemistry
1 answer:
Kamila [148]3 years ago
3 0
Nonpoint source pollution can include: Excess fertilizers, herbicides and insecticides from agricultural lands and residential areas. Oil, grease and toxic chemicals from urban runoff and energy production. Sediment from improperly managed construction sites, crop and forest lands, and eroding streambanks. :)

Hope that helps!

Why are construction sites considered major sources of water pollution NEED ASAP DAWG
AveGali [126]
Sources of water pollution on building sites include: diesel and oil; paint, solvents, cleaners and other harmful chemicals; and construction debris and dirt. When land is cleared it causes soil erosion that leads to silt-bearing run-off and sediment pollution. Silt and soil that runs into natural waterways turns them turbid, which restricts sunlight filtration and destroys aquatic life.

Surface water run-off also carries other pollutants from the site, such as diesel and oil, toxic chemicals, and building materials like cement. When these substances get into waterways they poison water life and any animal that drinks from them. Pollutants on construction sites can also soak into the groundwater, a source of human drinking water. Once contaminated, groundwater is much more difficult to treat than surface water.

A bulb is found to weigh 5.76 grams more when filled with air at 298 K and 1.00 atmosphere pressure than when it is evacuated. W
garik1379 [7]

Answer:

Subtract water vapor pressure from total pressure to get partial pressure of gas A: PA=1.03 atm- 1 atm=0.03 atm.

What is the total pressure of the gases at 298 K?

98.8 kPa

A sample of nitrogen gas is bubbled through water at 298 K and the volume collected is 250 mL. The total pressure of the gas, which is saturated with water vapour, is found to be 98.8 kPa at 298 K.

The total pressure of a mixture of gases can be defined as the sum of the pressures of each individual gas: Ptotal=P1+P2+… +Pn. + P n . The partial pressure of an individual gas is equal to the total pressure multiplied by the mole fraction of that gas.

How do you find the partial pressure of water in air?

e is vapor pressure Rv = R∗/Mv = 461.5Jkg−1K−1 and Mv = 18.01gmol−1, ϵ = Mv/Md = 0.622. The vapor pressure is the partial pressure of the water vapor. where es is in Pascals and T is in Celsius.

ExpHow do you find the pressure of h2?

For the high pressures in which hydrogen gas is often stored, the van der Waals equation can be used. It is P+a(n/V)^2=nRT. For diatomic hydrogen gas, a=0.244atm L^2/mol^2 and b=0.0266L/mol.lanation:

The mass of NaCl : 50.5 g

<h3>Further explanation  </h3>

The mole is the number of particles(molecules, atoms, ions) contained in a substance  

1 mol = 6.02.10²³ particles

Can be formulated

N=n x No

N = number of particles

n = mol

No = Avogadro's = 6.02.10²³

There are 5.20 x 10²³ units of NaCl, so mol NaCl :

\tt n=\dfrac{N}{No}\\\\n=\dfrac{5.2\times 10^{23}}{6.02\times 10^{23}}\\\\n=0.864~moles

Mass of NaCl(MW=71 g/mol) :

\tt mass=mol\times MW\\\\mass=0.864\times 58.44\\\\mass=50.49\approx 50.5~g
