What types of mixtures are these? (Homogeneous Mixture Hetergeneous Mixture)

Chemistry
1 answer:
salantis [7]3 years ago
4 0

Explanation: A <u>homogeneous mixture</u> is a solid, liquid, or gaseous mixture that has the same proportions of its components throughout any given sample. The components that make them up are evenly distributed and the appearance of the solution is uniform throughout.

A<u> heterogeneous mixture</u> has components whose proportions vary throughout the sample. The components of a heterogeneous mixture are visible and not uniform throughout. A heterogeneous mixture is simply any mixture that is not uniform in composition.

a) Peanuts and almonds mixed  together in a bowl  : The components(Peanuts and almonds) are visible in a bowl and are not evenly distributed and also not uniform throughout. So this is a 'heterogeneous mixture'.

b) Bucket full of sand and gravel  : The components(sand and gravel) are visible in a bucket and are not evenly distributed and also not uniform throughout. So this is a 'heterogeneous mixture'.

c) Cup of tea and sugar  : The components(tea and sugar) are evenly distributed and the appearance of the solution is uniform throughout. So this is a 'Homogeneous mixture'.

d) Food coloring dissolved in water : The components(Food coloring and water) are evenly distributed and the appearance of the solution is uniform throughout. So this is a 'Homogeneous mixture'.

A solution is saturated in CO2 gas and KNO3 at room temperature. What happens when the solution is warmed to 75°C?
nignag [31]

Answer:

gaseous CO2 bubbles out of the solution

Explanation:

We already know that the dissolution of a gas in water is exothermic. Hence, when the temperature of a solution containing a gas is increased, the solubility of the gas decreases and the gas bubbles out of the solution.

Similarly, the dissolution of KNO3 in water is endothermic. This implies that the solubility of the solid increases with increasing temperature.

Thus the solid becomes more soluble at 75°.

How would you expect a positive particle approaching another positive particle to behave?
JulijaS [17]

Answer:

They would produce a repulsive force to another

Explanation:

A positive particle approaching another positive particle will repulse it.

According to coulomb's law "like charges repel one another and unlike charges attract".

A charge is an intrinsic property of any matter.

When like charges e.g positive and positive or negative and negative charges are in the vicinity of one another, they repel each other.

When unlike charges; positive and negative are brought together, they simply attract one another.

Therefore, we expect that a positive particle approaching another positive particle will repel one another.
