3. In elastic deformation, the deformed body returns to its original shape and size after the stresses are gone. In ductile deformation, there is a permanent change in the shape and size but no fracturing occurs. In brittle deformation, the body fractures after the strength is above the limit. 
4. Normal faults are faults where the hanging wall moves in a downward force based on the footwall; they are formed from tensional stresses and the stretching of the crust. Reverse faults are the opposite and the hanging wall moves in an upward force based on the footwall; they are formed by compressional stresses and the contraction of the crust.  Thrust faults are low-angle reverse faults where the hanging wall moves in an upward force based on the footwall; they are formed in the same way as reverse faults. Last, Strike-slip faults are faults where the movement is parallel to the crust of the fault; they are caused by an immense shear stress. 

I hope this helped! These are COMPLEX questions though! =D

A sample of an element has a volume of 78.0 mL and a density of 1.85 g/mL. What is the mass in grams of the sample?
abruzzese [7]

Hey there!:

density = 1.85 g/mL

volume = 78.0 mL

Mass = ??

therefore:

D = m / V

1.85 = m / 78.0

m = 1.85 x 78.0

m = 144.3 grams

Hope this helps!

If 7.6 moles of H2O are produced from the reaction how many moles of O2 were used?
elena-14-01-66 [18.8K]

Answer:

Number of moles of oxygen used=13.5moles

Explanation:

To know the number of moles of oxygen used, first calculate the molar mass of water.

H2O=(2*1)+(1*16)

=2+16

18g/mol of H2O

The moles of H2O is 7.6 moles

So first, find the molar mass of oxygen

O2=2*16

=32g/mol

Then, number of moles of oxygen is equal to molar mass of oxygen divide by the molar mass of water times the number of moles of water

No. moles of O2=[32g/mol]/[18g/mol] *7.6moles

Moles of O2=1.778*7.6moles

No.moles of O2=13.5 moles

Therefore, the number of moles of oxygen used was 13.5moles

As the volume of a 1 mole sample of gas increases, with the temperature remaining constant, the pressure exerted by the gas:
Vinvika [58]
I believe the correct answer would be decreases. At constant temperature, the volume and pressure are inversely related that is when one value increases the other decreases or as one decreases the other increases. Hope this helps. Have a nice day.
