Chemistry

Lapatulllka [165]3 years ago
6 0

Answer : A piece of jewelry can range from a small earring to a large necklace. So, in this case, there is varying number of moles of silver atoms may be present in a piece of jewelry.

Also, it can happen that all jewelry doesn't contains silver in them. Thus, there is no specific answer to this question.


But if the weight of silver is known then we can calculate the atoms in it by comparing 1 mole with avogadro number of atoms.

Answer:

Hope this helps :)

2. Matter is everything around you. Atoms and compounds are all made of very small parts of matter.

3. Solid, liquid and, gas

4. False

5. Our weight on moon is less than it would be on Earth due to a difference of the strength of gravity on the moon.

6. Physical changes only change the appearance of a substance, not its chemical composition. Chemical changes cause a substance to change into an entirely substance with a new chemical formula. Chemical changes are also known as chemical reactions.

A sample of gas has a volume of 215 cm3 at 23.5 degrees Celsius and 84.6kPa what volume will the gas occupy at stp
miss Akunina [59]

The volume of the gas that occupy at STP is 165. 28 cm^3

calculation

by use of combined gas law that is P1V1/T1=P2V2/T2, where

P1=84.6 kpa

T1=23.5 +273=296.5 K

V1=215 cm^3

At STP T= 273 K and P= 101.325 Kpa

therefore p2 = 101.325 Kpa and T2 = 272 K V2=?

by making V2 the subject of the formula V2 =T2P1V1/P2T1

V2 = 273 K x 84.6 Kpa x 215 cm^3/ 101,.325 Kpa x296.5 K =165.28 cm^3
