Answer:

To identify a pure liquid substance using the physical properties of solubility, density, and boiling point. The physical properties of a pure substance can be measured without changing the composition of the substance.

Explanation:

The three-dimensional coordination number of the face-centered cubic arrangement  has a coordination number of 12 and contains 4 atoms per unit cell.

The coordination number, also known as ligancy, of a central atom in a molecule or crystal is the sum of all the atoms, molecules, or ions that are linked to it. This value is used in crystallography and materials science. A ligand is the ion, molecule, or atom that surrounds the center ion, molecule, or atom.

The number of atoms, ions, or molecules that a central atom or ion bears in a complex or coordination compound or in a crystal as its near neighbors is known as the coordination number, also known as ligancy.

In contrast to oxidation state, which is a number assigned to an element in chemical combination and represents the number of electrons lost or gained by an atom of that element in the compound, co-ordination number is the number of co-ordination bonds with which the ligands are bound to the central ion.

Thus, the face-centered cubic arrangement  has a coordination number of 12 and contains 4 atoms per unit cell.

Answer:8.334×10^-6 moles

Explanation:

a mole is 6.023×10^23

5.02×10^18 ÷ 6.023×10^23=8.33×10^-6

Answer:

The is less friction on an icy surface

Explanation:

This is because when u walk on plain ground there is steady friction on the surface but when u walk on an icy floor these is barely any friction which is why it's hard to walk on.

Answer:

There is less friction on an icy surface.

Hope that helps.

Explanation:

Answer: A increase

Explanation: The temperature of room will increase. If a refrigerator door is open then more flow rate of coolant is required in order to maintain lower temperature So the compressor will be running continuously also heat exchange happening through condenser increases the room temperature rather than decreasing.

Explanation:

most common elements that bond with oxygen is Hydrogen (H2) to form water

By definition, electrolysis is the use of an electric current to cause a chemical reaction which wouldn't otherwise happen. In a chemical change, bonds are either broken or formed. Electrolysis is a chemical change because, in the process of electrolysis, bonds are broken or formed.

Answer:

C. size and shape

Explanation:

Physical properties such as size, shape, color, density, magnetism or the

ability to sink or float can be used to separate the substances in a mixture..

Filtration is when matter is passed through a filter and the larger particles

are separated out. Magnets can be used to separate magnetic matter from

non-magnetic matter in a mixture. Objects that float when placed in water

can be separated from those that don’t by placing the mixture in water.

Answer:

17.19%

Explanation:

mass of oxygen = 7.221 - (1.990 + 2.341)

= 2.890g

Empirical formula of the compound

For carbon,

1.990/12 = 0.1658

For hydrogen,

2.341/1 = 2.341

For oxygen,

2.890/16 = 0.1806

0.1658 ÷ 0.1658 = 1

2.341 ÷ 0.1658 = 14.11

0.1806 ÷ 0.1658 = 1.089

Empirical formula of the compound= CH14O

Molar mass= (1×12) + (14×1) + (1×16)

= 12+14+16

= 42g/mol

percentage composition= 7.221/42 × 100

= 17.19%

Answer: During the summer, the sun's rays hit the Earth at a steep angle. ... Also, the long daylight hours allow the Earth plenty of time to reach warm temperatures. During the winter, the sun's rays hit the Earth at a shallow angle. These rays are more spread out, which minimizes the amount of energy that hits any given spot.

Substances having fixed chemical proportions will have fixed boiling and melting points. This is the reason that Pure substances have specific melting and boiling points because their chemical proportions are fixed. Mixtures melt and boil over a range of temperatures
