D a baiiiiiiiiii good luck
Answer:
b. changing the compound changes the absorbance behavior.
Explanation:
- Option a) would be akin to modifying the <em>path length</em>, b.
- Option b) would involve using a different solute, as such, there would be another <em>molar absortivity</em>, ε.
- Option c) would decrease the<em> concentration</em> (c) of the solute, which would explain why the absorbance would decrease as well.
Answer:
When a large, fissile atomic nucleus such as uranium-235 or plutonium-239 absorbs a neutron, it may undergo nuclear fission. The nucleus splits into two or more lighter nuclei, releasing kinetic energy, gamma radiation, and free neutrons.
Explanation:
Hope this helps. :)
Answer: The volume of solution is 0.0459 L
Explanation:
Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution
where,
n = moles of solute
= volume of solution in L
moles of HCl (solute) = 
Now put all the given values in the formula of molality, we get
Therefore, the volume of solution is 0.0459 L
Topaz and quartz
Explanation:
Topaz and quartz are minerals that will scratch feldspars but will not scratch corundum. Corundum is one of the hardest substance based on moh's scale.
The hardness of a mineral is its resistance to deformation. A mineral is harder than another if it can scratch it.
The moh's scale of hardness list minerals in the order of their hardness:
- Talc
- Gypsum
- Calcite
- Fluorite
- Apatite
- Orthoclase
- Quartz
- Topaz
- Corundum
- Diamond
Diamond is the hardest and talc is the softest.
Orthoclase is a feldspar.
