Answer:
Explanation: For most longer adjectives, the comparative is made by adding the word "more" (for example, more comfortable) and the superlative is made by adding the word "most" (for example, most comfortable). If a 1-syllable adjective ends in "e", the endings are "-r" and "-st", for example: wise, wiser, wisest.
Answer:
The molecular formula of the compound is
.
Explanation:
Given empirical formula of the compound is
.
Atomic mass of carbon = 12 u
Atomic mass of hydrogen = 1 u
Atomic mass of oxygen = 16 u
Empirical formula mass of compound = ![\left ( 12\times 2+4+16 \right ) = 44 \textrm{ g/mol}](https://tex.z-dn.net/?f=%5Cleft%20%28%2012%5Ctimes%202%2B4%2B16%20%5Cright%20%29%20%3D%2044%20%5Ctextrm%7B%20g%2Fmol%7D)
Molecular mass of compound = 176 g/mol
![n = \displaystyle \frac{176}{44} = 4](https://tex.z-dn.net/?f=n%20%3D%20%5Cdisplaystyle%20%5Cfrac%7B176%7D%7B44%7D%20%3D%204)
Molecular formula = n
Empirical formula
Molecular formula = 4
Molecular formula of the compound is ![C_{8}H_{16}O_{4}](https://tex.z-dn.net/?f=C_%7B8%7DH_%7B16%7DO_%7B4%7D)
Answer:
There are 4,46x10e-4 moles of CaCl2 (0,000446 mol)
Explanation:
A molar solution indicates the amount of moles of solute (in this case CaCl2) in 1 liter of solution (1000ml).
1000ml -----0,105 mol CaCl2
4, 25 ml----x=(4,25 ml x0,105 mol CaCl2)/1000ml= 4,46x10e-4 mol CaCl2
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.

Increased air temperatures decrease the salinity of the ocean since more ice is melting adding more fresh water to the oceans, therefore slowing down the great ocean conveyor belt.
<h3>What is an ocean conveyor belt?</h3>
Ocean conveyor belt system in which water moves between the cold depths and warm surface in oceans throughout the world.
Increases in temperatures of surrounding entities like ice and an increase in precipitation adds fresh water into the sea, which lower salinity. Seawater with lower salinity is lighter in density and won't sink as much as denser water.
As the seawater gets saltier, its density increases, and it starts to sink. Surface water is pulled in to replace the sinking water, which in turn eventually becomes cold and salty enough to sink. This initiates the deep-ocean currents driving the global conveyer belt.
Hence, option A is correct.
