A type of rock that forms directly from precipitates of hot water is called a <u>hydrothermal</u> rock
What is a hydrothermal rock?
- Hydrothermal essentially means “hot water.”
- Hydrothermal rocks are those rocks whose minerals crystallized from hot water or whose minerals have been altered by hot water passing through them.
- Thus, these rocks are distinct from metamorphic rocks, which are created by solid‐state mineral transformations.
- In fact, many hydrothermal rocks (such as those that form from hot springs and geysers or crystallize as veins in cracks in other rocks) actually build up in layers, much as sedimentary rocks do.
- Veins result when hot water moves through cracks in the bedrock of the crust.
- Various minerals are precipitated on the sides of the crack as the temperatures decrease.
- The shape and orientation of the minerals depends on the temperature, pressure, and rate of flow.
- When all the available space in the crack has been filled with mineral deposits, the crack is sealed and the vein is complete.

Answer:
B) Utilitarian value
Explanation:
<u>In utilitarian value :</u>
- All our activities are controlled, designed adn fashoined by science.
- Science has entered in our daily activity.
- Without science, or existence wold become impossible.
- Standard of living.
- It is ver essential to have elementar knowledge for becoming usefull, productive member of the community invention.
Hence according to the given scenario, Utilitarian value best describes the type of value sam recieved. Hence, option B is right.
Well designed instructions should select use of a layered approach for lengthy instructions and separate each step visually.
Option: D
Explanation:
A well designed instruction implies an audio-visual effect which includes layered approach for lengthy instructions means writing of the whole things in proper segregation. And present each step with systematic presentation. Visual effect draws a significant place in the mind of a listener.
Well designed approach includes knit and cleanliness in presentation, transparency, symbolization, pointing and highlighting the useful points for better configuration and execution. This approach is more useful for attracting attention in presentation.
Answer:
fixation
Explanation:
Hello! The word fixation, in this case, refers to the action of stay, which generally symbolizes support. Alexis maintains a way to solve a problem that used to work, but not now because the object is much bigger, another strategy is necessary, not the one previously used.

The right answer for the question that is being asked and shown above is that: "C) CH3CH2MgBr, ether; then KMnO4, OH2 ; then H3O+; then Br2, FeBr3."
These are the following choices:
A) Br2, FeBr3; then KMnO4, OH2<span> ; then H</span>3O+
B) KMnO4, OH2<span> ; then H</span>3O+; then Br2, FeBr3
C) CH3CH2MgBr, ether; then KMnO4, OH2<span> ; then H</span>3O+; then Br2, FeBr3
D) CH3CH2Br, AlCl3; then Br2, FeBr3; then KMnO4, OH2<span> ; then H</span>3O+
