Answer:
Explanation:
Homogeneous mixture is a mixture in which the components of the mixture are in the same proportion throughout any sample extracted from the mixture while an heterogeneous mixture is a mixture in which the components of the mixture differ in term of proportion when different samples of the mixture are extracted and compared.
For example, a sandy water will have some parts (usually the bottom) of the mixture with more sand than other parts of the mixture, hence, it (sandy water) is a heterogeneous mixture. While salty and ocean water has it's salt dissolved in the same proportion throughout the water in the mixture, hence salty and/or ocean water is a homogeneous mixture.
Sandy water can be separated by filtration (i.e using a filter paper to separate the sand from the water when the mixture is poured over a filter paper) while salty and ocean water can be separated by distillation (i.e boiling of the mixture so the water molecules can boil and move through a tube as gas or steam into another container where they are cooled and converted back to liquid or water while leaving the solid salt component of the mixture in the boiling tube).
The volume of an object is how much space can fit inside it. To find the volume of an object, you multiply its length, times its width, times its height. The end result is the volume, which is measured in cubed units (inches sub 3).
A=79, N=44 lmk if I’m wrong ?
To find the pH, you have to do -log[H] which is around 7.02228
Answer:
0.4mol/L
Explanation:
Data obtained from the question include:
Number of mole of NaOH(solute) = 0.20 mole
Volume of solution = 0.50 L
Molarity =.?
Molarity is simply mole of solute per unit litre of a solution. This can represented mathematically as:
Molarity = mole of solute /Volume of solution
Molarity of NaOH = 0.2mol/0.5L
Molarity of NaOH = 0.4mol/L
