Solute particles can be atoms, ions or molecules.
Explanation:
Solute is the material which has to be mixed in the solvent to prepare a solution. So the concentration of solute should be less than the solvent. Also the solute and solvent should be of same nature other they will not dissolve with each other. The solute can be made up of atoms, ions or molecules depending upon the solvent. If the solvent concentration is in moles, then the solute concentration can be taken as atoms, ions or molecules. Also the saturation point plays a main role in deciding the kind of particles taken for the solute.
Answer:
According to avogadro's law, 1 mole of every substance contains avogadro's number
of particles and weighs equal to its molecular mass.
To calculate the moles, we use the equation:
a. moles in 14.08 g of
= 
molecules in 14.08 g of
= 
b. moles in 17.75 g of NaCl = 
molecules in 17.75 g of
= 
formula units 17.75 g of
= 
c. moles in 20.06 g of
= 
formula units in 20.06 g of
= 
Answer:
M
Explanation:
Equation for the reaction is as follows:
+
⇄ 
By Applying the ICE Table; we have
+
⇄ 
Initial x 0.0025 M 0.0010 M
Change 0 0 0
Equilibrium x 0.0025 M 0.0010 M
![K_c =\frac{[CO_2]^2}{[CO]^2[O_2]}](https://tex.z-dn.net/?f=K_c%20%3D%5Cfrac%7B%5BCO_2%5D%5E2%7D%7B%5BCO%5D%5E2%5BO_2%5D%7D)
Given that
; Then:






M
∴ The equilibrium concentration of CO =
M
Answer:
0.1 M is the answer and I have explained it in the attachment below.
Hope this helped!
1) Answer: compounds
For example H2O, CO2, KNO3, H2SO4, CH4 are all compounds. All the molecules have the same composition. The composition of a molecule of H2O is the same of all molecules of H2O.
It is not the same for solutions, mixtures or colloids.
2) Answer: <span>both an element and made of one kind of atom.
Compounds can be broken into the elements that constitue them.
3) </span><span>When a physical change in a sample occurs, a change in shape, temperature or volume can happen.
Examples:
Shape change: fold a paper
Temperature change: evaporation of water absorbs heat from the surroundings.
Volumen change: boiling liquid causes the volume to increase.
You'd likely miss one choice. Compoistion does not change when physical change occurs.
