Answer:
Molecules are moving faster in the glass of Steam.
Explanation:
The three physical states of H₂O are Ice (Solid state), Water (Liquid state) and Steam (Gas state) respectively.
As we know the particles (i.e. molecules) in solid state are stationary and they are unable to change their position and are only vibrating therefore we can omit the option of Ice.
When heat is provided to Ice it melts into liquid water. The molecules are still interacting via intermolecular forces. In this state the molecules are not stationary. They exist in the form of layers (due to intermolecular forces) and these layers slide over each other hence, resulting in the change of position of molecules.
While, when liquid water is further heated it converts into steam ( a gas sate). In this state the molecules are not interacting with each other. They move faster in random directions and collide with each other. Hence, this is the correct answer.
Do we get multiple choice
Answer:
it would be 78 degrees higher
Explanation:
Hey there!
Ba(NO₃)₂
Ba: 1 x 137.327 = 137.327
N: 2 x 14.007 = 28.014
O: 6 x 16 = 96
-----------------------------------
261.341 g/mol
The molar mass of Ba(NO₃)₂ is 261.341 g/mol.
Hope this helps!
Answer:
A mixture
Explanation:
The substance whose magnetic properties is tested is mixture of many compounds, elements or molecules.
A mixture has the following properties:
- Their composition is indefinite
- Their constituents retain their identity
- Constituents react differently to changed conditions
- Their constituent can easily be separated by physical procedures.
Since a part of the mixture responds differently to magnetism, we can say, the other part is made up of a different set of compound.
