7 0

Answer:

hardness-Hardness is the ability of a material to resist deformation

luster-the way light interacts with the surface of a crystal

color-the quality of an object or substance with respect to light reflected by the object

streak- the color of the powder produced when it is dragged across an un-weathered surface.

specif gravity-the density of that object divided by the density of water cleavage -the tendency of a mineral to break along smooth planes

fracture-any separation in a geologic formation

tenacity-refers to a mineral's toughness or resistance to breaking or being deformed.

lol sorry that took awhile

Tems11 [23]
No, according to physics no work has been done.

Work must have been done by muscular force but in terms of physics no work has been done.

In physics,work is said to be done only if the force applied produced some kind of displacement in the direction of force.

In this example provided, no work has been done since the boulder doesn't get displaced,it continues to remain at its original position.

Debora [2.8K]

Hey there!:

Molar mass:

CHCl3 = ( 12.01 * 1 )+ (1.008 * 1 ) + ( 35.45 * 3 ) => 119.37 g/mol

C% =  ( atomic mass C / molar mass CHCl3 ) * 100

For C :

C % =  (12.01 / 119.37 ) * 100

C% = ( 0.1006 * 100 )

C% =  10.06 %

For H :

H% = ( atomic mass H / molar mass CHCl3 ) * 100

H% = ( 1.008 / 119.37 ) * 100

H% = 0.008444 * 100

H% = 0.8444 %

For Cl :

Cl % ( molar mass Cl3 / molar mass CHCl3 ):

Cl% =  ( 3 * 35.45 / 119.37 ) * 100

Cl% =  ( 106.35 / 119.37 ) * 100

Cl% = 0.8909 * 100

Cl% = 89.9%


Hope that helps!

Construct a simulated 1H NMR spectrum for ethyl acetate by dragging and dropping the appropriate splitting patterns into the box
Ksju [112]

Answer:

The simulated 1H NMR spectrum for ethyl acetate is shown in the drawing attached.

Explanation:

To construct this NMR it is necessary to identify the essential components that can produce resonance peaks.

Two main groups can be identified, the acetyl group containing a sub-component (CH3) capable of producing a resonance peak, and the ethyl group containing two components (CH2 and CH3) each of which can produce on its own its own resonance peak.

The electronic configuration of an atom of element X is 2,8,2 what will be the valency of the element x
KIM [24]

The element is Magnesium

  • It has total 12 electrons

it has electronic configuration

\\ \sf\longmapsto 2,8,2

or

\\ \sf\longmapsto 1s^22s^22p^63s^2

In valence cell it has 2 electrons and therefore its valency is 2
