Answer:
A chemical reaction is a process in which one or more substances, also called reactants, are converted to one or more different substances, known as products. ... A chemical reaction rearranges the constituent atoms of the reactants to create different substances as products.

I believe it is D as you are hearing the copper tube
The gamma-ray emitting technetium-99m (metastable) is widely used for medical diagnostic studies. Several chemical forms are used to image different parts of the body. Technetium is a remarkable corrosion inhibitor for steel, and adding very small amounts can provide excellent protection.
hope that helps you :)

0.00162 is the Ksp of Ag2CO3 at 10 degrees.
Explanation:
Ag2CO3(s) --- 2Ag+
(aq) + CO3 ^-2(aq)
The product of molar solubility of each ion in moles/litre gives the solubility product.
The molar solubility of Ag2CO3 is 0.074 M at 10 degrees.
From the above reaction we can see that
2 Moles of Ag and 1 mole of carbonate ions,
So, [Ag2CO3]= 2[Ag]^2[CO3^2-]
Ksp of Ag+= 2*0.074
= 0.148
Ksp of CO3^-2= 0.074
= 0.148
Ksp of AgNO3= [0.148]^2 [0.074]
Ksp of AgNO3 = 0.00162 AT 10 degrees
