Every day on his ride to school, Max sees some sedimentary rock. He starts to wonder: Could material from this sedimentary rock
Sloan [31]

Material from this sedimentary rock ever forms igneous rock, <u>Option D. Yes, if the sedimentary rock is moved below Earth’s outer layer and exposed to energy from Earth’s interior, it can melt into liquid rock and form </u><u>igneous rock.</u>

Sedimentary rocks are shaped from pre-existing rocks or pieces of soon-as-dwelling organisms. They form from deposits that collect on this planet's floor. Sedimentary rocks regularly have special layering or bedding.

Igneous rock, or magmatic rock, is one of the 3 primary rock kinds, the others being sedimentary and metamorphic. Igneous rock is shaped via the cooling and solidification of magma or lava. The magma may be derived from partial melts of existing rocks in either a planet's mantle or crust.

Every day on his ride to school, Max sees some sedimentary rock. He starts to wonder: Could material from this sedimentary rock ever form igneous rock?

A. No, igneous rock can only form out of other igneous rocks. Sedimentary rock cannot change into igneous rock.

B. No, igneous rock forms under Earth’s outer layer due to energy from Earth’s interior, but the sedimentary rock is only at Earth’s surface.

C. Yes, if the sedimentary rock is exposed to energy from the sun at Earth’s surface for a long enough time, it can melt into liquid rock and form igneous rock.

D. Yes, if the sedimentary rock is moved below Earth’s outer layer and exposed to energy from Earth’s interior, it can melt into liquid rock and form igneous rock.

Calculate the volumeof 1.0M NaOH necessary to completely neutralize 100mL of 0.50M of phosphoric acid (H3PO4)?
blondinia [14]

Answer:

50 mL

Explanation:

In case of titration , the following formula is used -

M₁V₁ = M₂V₂

where ,

M₁ = concentration of acid ,

V₁ = volume of acid ,

M₂ = concentration of base,

V₂ = volume of base .

from , the question ,

M₁ =  0.50M

V₁ = 100 mL

M₂ =  1.0M

V₂ = ?

Using the above formula , the volume of base , can be calculated as ,

M₁V₁ = M₂V₂

substituting the respective values ,

0.50M * 100 mL =  1.0M * V₂  

V₂  = 50 mL

A 32.0-g sample of HF is dissolved in water to give 2.0 × 102 mL of solution. The concentration of the solution is:
guajiro [1.7K]

 The concentration of the  solution is  8 M


 <u><em>calculation</em></u>

<em>  </em>Concentrati<em>on   =  moles/volume  in liters</em>

<em>  </em><em>step 1: find moles of HF</em>

<em>moles  of HF  =mass/molar mass</em>

<em>molar mass of  HF =  1+  19 )= 20 g/mol</em>

<em> moles is  therefore = 32.0  g/ 20 g/mol= 1.6  moles</em>

<em>Step 2:  convert  ml to L</em>

<em>volume in liters = 2.0 x 10^2 / 1000 =0.2 l</em>

<em>step 3: find the concentration</em>

<em>concentration  =  1.6 mol  / 0.2 l = </em><em>8 M</em>
