Answer:
All liquids are fluids but not all fluids are liquids. Fluids basically describe anything that can flow as a result of a difference in pressure between two points. Liquids on the other hand are a subset of fluids. Liquids are the incompressible fluids. These are the fluids who's density does not change sharply with pressure.
Gases are also fluids, they form the compressible fluids. They do flow as a result of difference in pressure between two points but at the same time they can be compressed or expanded. Their density fluctuates with pressure.
Hence fluids consist of 2 mutually exclusive groups of compressible and incompressible fluids. Liquids are the incompressible fluids and hence form a subset of the more general term fluid.
Answer:
0.43×10²³ atoms
Explanation:
Given data:
Mass of LiBrO₂ = 4.28 g
Number of atoms of oxygen = ?
Solution:
Number of moles = mass/molar mass
Number of moles = 4.28 g/ 118.84 g/mol
Number of moles = 0.036 mol
We can see 1 mole of LiBrO₂ contain 2 mole of oxygen atm.
0.036 mol × 2 = 0.072 mol
1 mole contain 6.022×10²³ atoms
0.072 mol × 6.022×10²³ atoms / 1mol
0.43×10²³ atoms
Answer : The amount of heat released would be, (3) 811.68 kcal
Explanation : Given,
Moles of carbon monoxide = 12.0 mole
Enthalpy change = -135.28 kcal
The given balanced chemical reaction is,
From the balanced chemical reaction we conclude that,
As, 2 moles of carbon monoxide react to release heat = 135.28 kcal
So, 12.0 moles of carbon monoxide react to release heat = 
Thus, the amount of heat released would be, 811.68 kcal
Solution:
By the following ways the polar molecule doesn’t mix with non-polar molecule
Polar molecules have a portion of their molecule which, relative to the rest of the molecule, is more negative.
Water, for example, has a bent, or V-shape, due to the 2 lone electron pairs on oxygen. This makes the oxygen end more negative than the hydrogen end. This negative area allows for hydrogen bonding between that molecule and other molecules which are also polar.
Non-polar molecules don't have a portion of the molecule which is more negative than the rest. An example of this is a hydrocarbon, like butane. Because there is no relatively negative region to the molecule, it cannot partake in hydrogen bonding and therefore does not mix with polar molecules.
Thus we can conclude that Polar mixes with polar; non-polar mixes with non-polar.
To predict the solubility of the compounds you should base on solubility tables.
I used one from wikipedia. If you google "solubility table" you will find this table as first option.
There I found that nickel, potassium and sodium chlorides are very soluble with solubilities of two digits. While lead clhoride has a solubility close to 1 g per 100 g of water. Then lead is the ion that will precipitate with certainty.
