The correct answer is A. In the process of freezing, a liquid loses kinetic energy and turns into a solid.

Explanation:

The kinetic energy in a substance is produced by the movement of the participles in it. Additionally, this depends on the state of the substance, for example, in gases substances move freely and therefore produce more kinetic energy than in liquids in which the movement is more restricted or in solids in which particles only vibrate. This means, in the process of freezing that implies a liquid turning into a solid the particles lose kinetic energy as their movement is limited in a solid state.

Two chemist are trying to determine if their water sample is a mixture or pure substance. In their investigation they first filt
Effectus [21]

The correct answer is option B. Dirty water is a mixture of solid particles and liquid. It is both a mixture and pure substance.

The dirty water sample has both gravel and liquid water in it. After filtration the gravel is removed so the water sample looks clearer than before filtration. Liquid water is a pure substance because it is a compound that is made up of elements hydrogen and oxygen. Now the gravel is only physically combined with the liquid water, thus giving the water sample properties of a mixture. And like any mixture, gravel is physically separated through filtration from the liquid water.

Thus the water sample of the chemists is both a mixture and pure substance.

We identify nucleic acid strand orientation on the basis of important chemical functional groups. These are the _________ group
zloy xaker [14]

Answer:

We identify nucleic acid strand orientation on the basis of important chemical functional groups. These are the <u>phosphate</u> group attached to the 5' carbon atom of the sugar portion of a nucleotide and the <u>hydroxyl</u> group attached to the <u>3'</u> carbon atom

Explanation:

Nucleic acids are polymers formed by a phosphate group, a sugar (ribose in RNA and deoxyribose in DNA) and a nitrogenous base. In the chain, the phosphate groups are linked to the 5'-carbon and 3'-carbon of the ribose (or deoxyribose) and the nitrogenous base is linked to the 2-carbon. Based on this structure, the nucleic acid chain orientation is identified as the 5'-end (the free phosphate group linked to 5'-carbon of the sugar) and the 3'-end (the free hydroxyl group in the sugar in 3' position).

How do hot fluids act in metamorphism?
olga nikolaevna [1]

Answer:

Hot fluids are formed mainly of water and dissolved minerals. They can seep through rocks and chemically react with the minerals in the rocks potentially changing the composition of the rock. Metamorphic rocks can form from other metamorphic rocks.
