What is a chalk powder in a water it is solutionsuspension or a colloid?
When chalk powder is mixed with water, it forms a suspension. In a suspension, the particles of the chalk powder are not dissolved in the water but rather dispersed throughout, giving it a cloudy appearance. A colloid would involve smaller particles that are evenly dispersed and do not settle out over time.
Sand water a suspension only mixed together?
Yes
Will chalk powder in water form a solution?
Chalk powder, which is composed mainly of calcium carbonate, will not form a true solution when mixed with water. Instead, it will form a suspension where the particles of chalk remain suspended in the water without fully dissolving. If left undisturbed, the chalk particles may settle at the bottom of the container over time.
What gas does vinegar and chalk make if they are mixed together?
When vinegar (acetic acid) and chalk (calcium carbonate) are mixed together, they react to produce carbon dioxide gas, which creates bubbles. The chemical reaction can be represented by the equation: CaCO3 + 2CH3COOH -> Ca(CH3COO)2 + H2O + CO2.
What kind of mixture is chalk?
Chalk is a mechanical mixture, which means it is a combination of different substances that are physically mixed together but not chemically bonded. It is composed mainly of calcium carbonate and other minerals.
How long does it take chalk to dissolve in water?
Chalk consists of calcium carbonate, which is insoluble in water. Therefore, chalk does not dissolve in water but rather forms a suspension or slurry when mixed with water. The rate at which the chalk particles settle out of the water depends on factors such as particle size and water movement.
Is soil and water a solution suspension or a colloid?
Soil and water form a suspension when mixed together because the soil particles do not dissolve in water but remain dispersed throughout the liquid.
Is salt and pepper a suspension colloid or solution?
Salt and pepper are considered a mixture, not a solution or a colloid. In this case, salt and pepper are mechanically mixed together, but the individual components do not dissolve into each other or form a stable suspension.
Is oil and vinegar salad dressing a colloid mechanical mixture a suspension or a solution?
Salad dressing contains some kind of oil mixed with vinegar, and these two substances are immiscible; they do not dissolve in each other, although if you mix them together you can get a suspension (which is temporary).
What is a mixture in which particles are temporarily mixed together?
There are two outcomes when partickes mix. One is called a solution, the other is more temporary and is referred to as a suspension.

What will happen if chalk is mixed with water?
Not a lot!!!! Because chalk is the chemical 'calcium carbonate (CaCO3)'. Most carbonates are insoluble in water. So chalk would just lie there completely unreactive. However, if chalk is put in an acid , such vinegar (Ethanoic(Acetic) Acid), it will react. You will see effervescenc/fizzing/bubbles as carbon dioxide is liberated. Here are the two reaction eq'ns. CaCO3(s) + H2O(l) = CaCO3(s) + H2O(l) 2CH3COOH(aq) + CaCO3(s) = (CaCOO)^(2-)Ca^(2+) + H2O(l) + CO2(g).
