The answer is- Part washers use cleaning solutions that eventually become spent and must be disposed of properly.

Cleaning solutions: Cleaning solution is a liquid solvent or solution used to clean the working surfaces and the parts of a machine.

What type of cleaning solution is Part washers?

  • Parts washers are mechanical devices that are designed to be cleaned to remove debris, dirt, oil, paint, and other substances that could potentially contaminate parts to prepare them for assembly, packaging, or even painting.
  • They are basically used to clean parts to make them ready for functional use.
  • Cleaning solutions for washing used parts are considered a special waste because they can be hazardous waste and are waste from an industrial process.
  • Used solvents are almost always hazardous waste. Both solvent and aqueous parts washers produce a sludge that is usually hazardous because it contains toxic metals and solvents from the parts being cleaned.
  • Absorbents used to wipe parts after washing are also dangerous if they contain toxic metals in concentrations exceeding regulatory limits or listed hazardous solvents, and used oil may also contain hazardous waste.
  • Thus, these cleaning solutions must be disposed of properly.

What is the equation for density?<br> O D= m<br> V<br> OD=V<br> m<br> OD=m<br> OD=mv²
frosja888 [35]

Answer:

D = m/V

Explanation:

Density represents the following ratio:

Density (D) = mass (m) / volume (V)

In this formula, the volume is being divided from the mass. The typical units for mass is grams and the unit for volume is milliliters.

12.47 g of ammonium nitrate are dissolved in water, then diluted to 250 ml. What is the molarity of the resulting solution?
slega [8]
<h3><u>Answer;</u></h3>

= 0.6224 M

<h3><u>Explanation</u>;</h3>

Molarity is given by the formula;

Molarity = Number of moles/Volume

But moles = mass/Molar mass

Thus;

Moles = 12.47 g/80.043 g/mol

          = 0.1556 Moles

Therefore;

Molarity = 0.1556 moles/0.25

<h3>            <u>= 0.6224 M</u></h3>

Using the atomic masses and relative abundance of the isotopes of nitrogen given below, determine the average atomic mass of nit
mylen [45]
The formula for average atomic mass is :

mass of isotope A * % of isotope A + mass of isotope B * % of isotope B + ....

Now,
Here,
Average atomic mass of nitrogen = (14.003 * 99.63%) + (15.000 * 0.37%)
                                                 = (14.003 * 0.9963) + ( 15.000 * 0.0037)
                                                 = 13.951 + 0.056
                                                 = 14.007 a.m.u.
