What do physical changes do?

Answers

Great question!

Physical changes change the appearance of something or someone.

For example, let's say 2 cats get into a fight. One is left clean in the end of this, with no scratches or bites anywhere, so nothing has happened to it as a physical change.

However, the other cat is left scarred and with bite marks everywhere. All this has left the cat's once-beautiful coat now ragged and torn up. This is an example of a physical change.

Example when materials are prepared as fluids so they can be moved more easily

Answers

A simple, albeit slightly less useful example perhaps, is when a foundry, or individual metalworker, liquefies metal such as iron, aluminum, or steel so that it can be mixed in with specific forging agents or transferred around a workplace.

In general solids are easier to transport than liquids, but the above metal example is a valid one and the only other one that comes to mind is that of concrete. It is mixed as a liquid and transported as such, but then sprayed or laid down to dry and form a solid surface or filler.

Explanation:

Both gases and liquids are fluids, therefore technically, the gas to liquid stuff does not work.

In addition to the LN2 and LO2 the opposite guys mention, organic compound gases also are oftentimes created into liquids. LPG is of a composition that it liquefies at low pressures. LNG is gas that's terribly cold in order that it becomes a liquid in order that tons are shipped during a tanker.

Industrial users additionally build solids into liquids for transport in pipelines. as an example, coal slurries area unit typically used. Coal is ground up into the mud, and mixed with water, and may then be pumped up through pipelines. There are different sorts of slurries, like wood chips/water in paper mills, sand/water mixture in dredging machines.

what is the volume of 24.0 g of oxygen gas at stp? i need to show work and i just cant get it. please help?

Answers

Molar mass O₂ = 16 * 2 = 32.0 g/mol

1 mol -------- 32.0 g
? mol -------- 24.0 g

mol = 24.0 * 1 / 32.0

= 0.75 moles

1 mol ------- 22.4 L ( at STP )
0.75 moles --- ?

v = 0.75 * 22.4 / 1

v = 16.8 L

A compound has the molecular formula C6H12O6. Which class of organic compounds does it belong to?

Answers

Answer:

Explanation:

C6H12O6 is the formula of simple sugar, glucose. The primary elements in the glucose are carbon, hydrogen and oxygen. Thus, glucose belongs to the group of carbohydrate.

Carbohydrates are group of bio molecules that comprises of carbon , hydrogen and oxygen as its constituents elements. Thus all the substances that contain all three element primarily C, H and O are considered as carbohydrates.

Final answer:

The compound with the molecular formula C6H12O6 belongs to the class of organic compounds known as carbohydrates, particularly monosaccharides. The most common molecule of this type is glucose which serves as a crucial energy source for living organisms.

Explanation:

The compound with the molecular formula C6H12O6 pertains to the class of organic compounds known as carbohydrates, particularly monosaccharides.

Monosaccharides are simple sugars and they are the basic units of carbohydrates. The most common monosaccharide is glucose, which indeed has the formula C6H12O6.

Monosaccharides serve as a crucial energy source for living organisms, and they can link together to form more complex carbohydrates such as disaccharides and polysaccharides. The structure of C6H12O6 consists of six carbon atoms, twelve hydrogen atoms, and six oxygen atoms.

C,H,O,+ 3HCI → C,HCl, + 3H20
right 5 possible mole ratios

Answers

Answer:

Here's what I get

Explanation:

I think this may be the equation you intended to write:

C₃H₅(OH)₃ + 3HCl ⟶ C₃H₅Cl₃ + 3H₂O

The mole ratios are the ratios of the coefficients in the balanced equation.

Here are some of the possible molar ratios.

C₃H₅(OH)₃:HCl = 1:3
C₃H₅(OH)₃:C₃H₅Cl₃ = 1:1
C₃H₅(OH)₃:H₂O = 1:3
HCl:C₃H₅Cl₃ = 3:1
HCl:H₂O = 3:3
C₃H₅Cl₃:H₂O = 1:3

A filament at which temperature would have the most light absorbed by a piece of yellow glass?

Answers

soft light (answer) is the filament between (2700k-3000k).
The higher the kelvin number the whiter the light.

3500k-4100k is bright white/cool white

5000k-6500k is daylight

\and those are the three primary colors of color temperature
