Metamorphic rock. I had this question last year. I hope I helped!

Answer:

Option (2) and (3)

Explanation:

Sedimentary rocks are the rocks formed due to the compaction and lithification of sediments. According to the rock cycle,  these <u>sedimentary rocks can change into both metamorphic as well as igneous rocks</u>.

Sedimentary rocks can turn into metamorphic rock if the rock is subjected to high-pressure and temperature conditions. For example, shale (sedimentary rock) changes into slate (metamorphic rock) due to the process of metamorphism.

The sedimentary rocks can also change into igneous rocks. When the sedimentary rock such as sandstone is subjected to extremely high pressure and temperature condition, then it starts to melt forming magma, and this magma when crystallizes (cools) it forms igneous rock. For example, granite.

Thus, the correct options are (2) and (3).

How is the sugar cube like a sedimentary rock?
noname [10]
This is heated until evaporation occurs and sugar crystals are precipitated. This is similar to how chemical sedimentary rocks are formed (like rock salt or cave limestone). It is then separated into small individual crystals. This can be representative of weathering and erosion of rock into sediment

PLEASEEE HELPPP I SUCK AT CHEM :(
Luda [366]

Answer:

a) H2SO4 + 2KOH -> 2H2O + K2SO4

b) 9.809 ml

Explanation:

Number of Moles = Mass/ Molar Mass

Therefore: Mass = Number of moles * Molar Mass

--------------------------------------------

Molar mass of H2SO4:

H2= 2.02

S= 32.07

O4= 64

--------------------------------------------

H2SO4 has the molar mass of 98.09

--------------------------------------------

the Moles of H2SO4 is given to be 0.100M

Therefore:

Mass= 98.09*0.1

          = 9.809g

---------------------------------------------------

Assuming that 1 g= 1 ml, the volume of sulfuric acid is 9.809 ml.
