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
I believe the answer is A. <span>wavelength and frequency. </span>
Answer:
1.02 moles of AlCl3
Explanation:
Consider the balanced reaction equation shown below;
2Al(s) + 3CuCl2(aq) -------> 2AlCl3 (aq) + 3Cu(s)
This is the balanced reaction equation for the reaction going on above. Recall that the first step in solving any problem is to accurately put down the chemical reaction equation. This balanced reaction equation always serves a reliable guide in solving the problem at hand.
Given that;
3 moles of CuCl2 yields 2 moles of AlCl3
1.53 moles of CuCl2 yields 1.53 × 2 / 3 =1.02 moles of AlCl3
Answer:
(a) 
(b) 
(c) 
Explanation:
Hello,
(a) In this case, since entropy remains unchanged, the constant 
should be computed for air as an ideal gas by:
Next, we compute the final temperature:
Thus, the work is computed by:
(b) In this case, since 
is given, we compute the final temperature as well:
And the isentropic work:
(c) Finally, for isothermal, final temperature is not required as it could be computed as:
