Which of the following is a heterogeneous mixture

1 answer:

3 0

Heterogeneous Mixtures aren't uniform and are separated in the mixture. They are usually more easily able to be separated. An example is milk and cereal. The cereal isn't uniform because the milk and cereal still are separated and have their own identities. (You can easily just remove cereal from milk using a strainer)

Homogeneous Mixtures are uniform in composition and the multiple elements have become one solution. These mixtures are hard to separate into their components. An example is tap water because it contains water as well as various minerals that can only be separated by performing chemical reactions.

Consider the nuclear equation below. Superscript 124 subscript 56 B a right arrow superscript 124 subscript 55 upper C s plus qu

nadezda [96]

Superscript o subscript negative 1 e.

Explanation:

The nuclear reactions is of 2 types, one is nuclear fusion and the other one is nuclear fission.

Nuclear fusion is nothing but the combining of 2 nuclei with an emission of energy along with an electron, proton or beta particle.

Nuclear fission is the break down of a nucleus into 2 or more nuclei along with an electron, proton or beta particle.

And the reaction is,

₅₆B¹²⁴ ₅₅C¹²⁴ + ₋₁e⁰

So the blank was filled by means of a beta particle.

Classify each of the following as either a physical change or a chemical change.

Mkey [24]

Answer:

(a) Dissolving sugar in water ⇒ physical change

(b) Crushing rock salt ⇒ physical change

(d) Digesting a chili dog ⇒ chemical change

Explanation:

Physical changes are those in which the substance does not alter its composition. They only involve changes of states of matter and the chemical substance is stil the same after the change occurs. By other hand, chemical changes are those in which new subtances are formed. So, the subtance is not the same after the change.

(a) Dissolving sugar in water ⇒ physical change; because we obtain a solution of sugar in water (sugar is stil sugar).

(b) Crushing rock salt ⇒ physical change; because we obtain crushed salt, but the chemical composition of the salt is not altered.

(c) Burning sulfur ⇒ chemical change; because sulfur is oxidized (chemical reaction) and new compounds are formed, for example sulfur dioxide.

(d) Digesting a chili dog ⇒ chemical change; because the digestion process is produced by the action of hydrocloric acid, and new compounds are formed.
