(1) copper (II) chloride
(2) aluminum acetate
(3) iron (III) hydroxide
(4) potassium sulfate
Iron (III) hydroxide is the least soluble compound as it has the lowest Ksp value.
The solubility is the amount of solute that can dissolve in a given volume of solvent at a particular temperature.
The solubility of substances can be compared using their their solubility products constant (Ksp) values.
Iron (III) hydroxide has the lowest Ksp value.
Therefore, Iron (III) hydroxide is the least soluble compound.

Answer:3
Explanation:
stated
Using Einstein’s famous equation, E = mc^2
Given mass, m = 0.112 kg and knowing c = 3.0 x 10^8 m/s, energy E can be determined
E = (0.112 kg)(3.0 x 10^8 m/s)^2
= 1.008 x 10^16 J
Hope this helps
Answer:
Joules is the energy equivalent of this .
Explanation:
Mass of hydrogen atoms in 1 kg of water = 112 g= 0.112 kg
Mass and energy related together and that expression was given by the famous scientist named Albert Einstein:
E = Energy related to mass m
c = Speed of the light
m = 0.112 kg , c =
Joules is the energy equivalent of this .
Answer:
3) Each sample has the same number of molecules
Explanation:
1 mol are 6,022x10²³ particles. Moles of a chemical substance represent the number of molecules that this chemical has.
Thus, one mol of oxygen are 6,022x10²³ molecules of oxygen and one mol of nitrogen are 6,022x10²³ molecules of nitrogen.
Right answer is:
3) Each sample has the same number of molecules.

Explanation:
Matter in which molecules have strong force of attraction are held tight together. Therefore, to break this force of attraction strong force is required.
This type of matter is know as solid. Also, it is known that solid substances have definite shape and volume.
Thus, we can conclude that a substance with a definite shape and volume is a solid phase of matter.
b. shape
c. size
d. shape and volume
At a constant temperature and pressure, liquids retain their volume of matter.
Matter is defined as total mass which occupy in space, all the physical structures are composed of matter, it can be present in three basic states such as solid, liquid, and gas.
The atoms are basic unit of matter and that make up the objects which can be visible and touched every day, the amount of matter in an object can be determined by its mass.
A physical property of matter is an independent of its chemical composition. Density, color, hardness, melting and boiling points, and electrical conductivity are the examples.
Some characteristics like density, color, mass, volume, length, malleability, melting point, hardness, odor, temperature are some properties of matter.
