Metamorphic rock can form from sedimentary rocks , matamorphic rocks, and igneous rocks.

Answer: sedimentary rock , metamorphic rock and igneous rock.

The answer is:

Sedimentary rock, metamorphic rock, and igneous rock.

Any type of rock can be a metamorphic rock. Metamorphic rocks are formed when a rock (any kind of rock) undergoes immense heat and pressure. If melting does not occur, it will become a metamorphic rock. If it melts, it becomes magma and from there, the magma, could eventually become an igneous rock and the rock cycle will start again.

To determine the molarity of naoh solution, student took 3.5 g of khp (khp – potassium hydrogen phthalate; molar mass = 204.22 g

alexandr402 [8]

Hello!

First, we need to determine the concentration of KHP. This concentration is:

$\frac{3,5g KHP }{50 mL sol}* \frac{1000 mL}{1 L}* \frac{1 mol KHP}{204,22 g KHP}=0,343 M$

The neutralization reaction is:

KHP + NaOH → NaKP + H₂O

At the equivalence point:

$moles NaOH=moles KHP \\ \\ cNaOH*vNaOH=cKHP*vKHP \\ \\ cNaOH= \frac{cKHP*vKHP}{vNAOH}= \frac{0,343M*50mL}{(24,65 mL-1,85 mL)} =0,75 M$

So, the concentration of NaOH is 0,75M

Have a nice day!

How do scientists measure the idea of time so long ago?

aleksklad [387]

The Ancient Egyptians used simple sundials and divided days into smaller parts, and it has been suggested that as early as 1,500BC, they divided the interval between sunrise and sunset into 12 parts. ... Known as a clepsydra, it uses a flow of water to measure time.

a gas occupies 600.0 ml at 20.00 degrees C and 70.00kPa what will be the pressure at 40.00 degrees C and 150.0mL?

Zina [86]

Answer:

P₂ = 299.11 KPa

Explanation:

Given data:

Initial volume = 600 mL

Initial pressure = 70.00 KPa

Initial temperature = 20 °C (20 +273 = 293 K)

Final temperature = 40°C (40+273 = 313 K)

Final volume = 150.0 mL

Final pressure = ?

Formula:

P₁V₁/T₁ = P₂V₂/T₂

P₁ = Initial pressure

V₁ = Initial volume

T₁ = Initial temperature

P₂ = Final pressure

V₂ = Final volume

T₂ = Final temperature

Solution:

P₂ = P₁V₁ T₂/ T₁ V₂

P₂ = 70 KPa × 600 mL × 313 K / 293K ×150 mL

P₂ = 13146000 KPa .mL. K /43950 K.mL

P₂ = 299.11 KPa
