Mix orange juice powder to water is what kind of mixture? A. Heterogeneous mixture C. Homogenous mixture B. Insoluble mixture D. Mixture
Biko, nilupak and buko salad is an example of what kind of mixture? A. Solid C. Heterogeneous B. Liquid D. Homogenous
Let us assumed that the composition varies from one region to another, with at least two phases that remain separate from each other, with clearly identifiable properties. This is a heterogeneous or ___ mixture? A. uniform C. Non-uniform B. dissolution D. Solution
It is the combination of two or more substances that are not chemically combined and a new substance was formed. What do you mean by this? A. It is solid C. It is gas B. It is liquid D. It is mixture
There are five kinds of solution. Gas in liquid is one of it, therefore, which of the given example is one of the solution? A. Air and water C. Oxygen and salt B. Cola or Soft drink D. Rocks and solvent
Homogeneous mixture has the same properties. It means that the substances mixed thoroughly and after stirring, it appeared as one substance. You can no longer distinguish one component from the other. What is the other term for homogenous mixture? A. Solution C. solute B. Dissolution D. Solvent
When sugar dissolves in water, the two substances appear as one. The sugar particles can no longer be identified. However, the taste of the water proves that the sugar was not lost after mixing. Its chemical property is retained and so the water taste sweet. What kind of solution is this? A. Solid in liquid C. Liquid in liquid B. Solid in solid D. Gas in liquid
A sugar solution is prepared by adding dissolving sugar in water. Sugar solution consists of two components, namely, sugar and water. Which is solute? A. Water C. solution B. Sugar D. Components
In question number 10 (ten), which is solvent? A. Water C. solution B. Sugar D. Components
Do all solutes dissolve in all solvents? A. Yes C. Maybe B. No D. None of the above
Not all substance can be dissolved in water. What do you call the substances that can be dissolved in water? A. soluble C. solution B. insoluble D. Dissolution
What is the meaning of solubility? A. property of substance B. It is the ability of a solute to dissolve in a solvent at a given temperature. C. Clear to naked eye D. None of the above
Miscibility is another factor that affects the solubility of substances. It is the property of a substance to mix evenly and completely with another substance. Do you agree? A. Yes C. Maybe B. No D. Not at all
Which is not true about solubility? A. The higher the temperature, the faster a solute can be dissolved in a solvent B. The nature of solute and the amount of solvent also determine how fast the solute dissolves in a solvent. C. The size of the particles affects the dissolving process. The finer the particles are, the faster the solute dissolves. D. The manner of stirring is not a factor to dissolve a solute in a solvent.
Apply nail polish on your nails. When it dries up, remove the nail polish with acetone. Can you identify the factors that affect the solubility of the nail polish in acetone? A. Miscibility or nature of the solute and the solvent B. Size of the materials C. The tempearature D. None of the above
When the solute particles mixed with water, what do they become? A. Solvent C. soluble B. Matter D. Mixture
How do the solute particles in a suspension behave after mixing with solvent? A. settle at the bottom/ float in the water B. all particles appeared clearly C. It doesn’t dissolved in solvent D. A and B
A suspension is a heterogeneous cloudy mixture in which solute-like particles settle out of a solvent- like phase some time after their introduction. Do you agree? A. No C. Yes B. Not at all D. Maybe
What kind of mixture is suspension? A. Heterogeneous D. Gas in gas
What is an emulsion? A. It is a liquid dispersed in either a liquid or solid B. It is a solid dispersed in either solid or a liquid. C. These are suspensions of liquid or solid particles in a gas D. None of the above
Which mixtures cannot be separated through picking? A. grains and mongo seeds C. sliced fruits B. nails and pins D. Oil and vinegar
Which mixture can be separated through picking? A. Softdrinks C. creamer B. Orange juice D. Sliced mixed fruits

To separate the palay and pebbles, which process or separating of mixture is applicable? A. Sifting C. Picking B. Sieving D. Winnowing
What is winnowing? A. Is used to separate smaller solid particles from larger solid particles. B. It is the process of freeing (grain) from the lighter particles of chaff, dirt, etc. C. Picking of small particles to larger D. B and C
Which is the process of separating solid substances from a liquid through the use of a filter paper or any cloths that can be used as a filtering medium? A. Sifting C. Picking B. Sieving D. Filtration
What is an apparatus use as containing medium? A. Filter C. residue B. Filter medium D. Bottle
