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.

Answer:
The pressure of the gas is 224839.8 atm
Explanation:
As we know
PV = nRT
Substituting the given values, we get -
P * 1 L = 90.1 moles * 8.314 4621(75). J K−1 mol−1 * 300
P = 224839.8 atm
The pressure of the gas is 224839.8 atm
Answer:
The rate law is rate = k[NO][O₃]
Option E) is the right answer.
Explanation:
Hi there!
For this generic reaction:
A + B → products
the rate law will be:
rate = k[A]ⁿ[B]ᵃ
this reaction is n-order in A and a-order in B. The overall reaction is the sum of the orders of each reactant, in this case:
Overall order of the reaction = n + a
In our problem, we know that the reaction is first order in O₃ and second order overall. Then:
Overall order of the reaction = Order in NO + Order in O₃
2 = n + 1
2 - 1 = n
n = 1
Then, the reaction is first order in NO and first order in O₃.
The rate law will be:
rate = k[NO][O₃]
The right answer is the option E).
