Answer:There is no change in identity of the substance and we can visually see a substance being drawn into wires. Hence ductility is not a chemical property, it is a physical property. Some examples of ductile materials, include metals such as copper, aluminium, silver, gold, etc.

Answer:
Explanation:
Radioactive decay follows the equation:
Ln [A] = -kt + ln [A]₀
<em>Where [A] is amount of isotope after time t: Our incognite,</em>
<em>k is rate constant: ln 2 / Half-life = 0.0231 years⁻¹</em>
<em>t are 60 years</em>
<em>[A]₀ is initial amount of isotope: 1.0g</em>
<em />
Replacing:
Ln [A] = -kt + ln [A]₀
Ln [A] = -0.0231 years⁻¹*60 years + ln 1.0g
ln [A] = -1.386
[A] = 0.25g
<em />
In the given situation, the reaction is-
NO + H2 ↔ Products
The rate of the reaction can be expressed (in terms of the decrease in the concentration of the reactants) as-
Rate = -dΔ[NO]/dt = -dΔ[H2]/dt
Now, if the concentration of NO is decreased there will be fewer molecules of the reactant NO which would decrease the its collision with H2. As a result the rate of the forward reaction would also decrease.
Ans) A decrease in the concentration of nitrogen monoxide decreases the collisions between NO and H2 molecules. the rate of the forward reaction then decreases.
Answer:
The solution warmed and the solubility of Q increased
