Brainlies ! which of the following correctly describes a mixture? the particles are chemically bonded together, and they retain their individual physical and chemical properties. the particles are not chemically bonded, and they can only combine in certain set ratios. the particles do not retain their individual chemical properties, and they can only be separated by chemical means. the particles have no set ratio for how to combine, and they can be separated by physical means.

Option (b) is the correct answer.

Explanation:

A mixture is a substance that contains two or more components mixed together in varying composition.

Components of a mixture never combine chemically with each other and hence, the components of mixture retain their individual properties.

For example, mud in water is a mixture.

Therefore, we can conclude that the statement, particles are not chemically bonded, and they can only combine in certain set ratios, correctly describes a mixture.

The option which correctly describes a mixture is: D. The particles have no set ratio for how to combine, and they can be separated by physical means.

A mixture can be defined as a combination of two (2) or more substances which are present in varied proportion (unfixed ratios). Also, a mixture can be visibly seen with our naked eyes and separated by physical means.

In Chemistry, there are two (2) main types of mixture and these are;

From the above definition of a mixture, we can deduce that the particles of a mixture have no set ratio for how to combine and they can be separated through the use of a physical separation technique.

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.
