↪ Hello miss "galaxyu035" here's your answer for the question you wrote.
Answer :
No, <u>we cannot</u> stir silver nitrate solution with a copper spoon <u>because</u> , copper is more reactive than silver. Thus,it would displace silver from the silver nitrate solution forming copper nitrate.

Answers with Explanations:
1. Why is knowledge of mineral properties important?
Knowledge of mineral properties is important because it <u>helps scientists know about the earth's history, particularly when it comes to "rock formations."</u> It is also essential in order to know which minerals are economically important.
2. Which properties might be useful in construction?
Minerals have many physical properties (<em>color, crystal form, hardness, luster, density, cleavage and fracture, etc.) </em>
When it comes to construction purpose, the mineral's malleability is very important. This is the reason why "iron" is one of the most important minerals being used in buildings. It's <em>malleability</em> allows it to be framed into "steel," which is then used to make even bigger infrastructures and skyscrapers.
3. In jewelry-making?
When it comes to "jewelry-making," the <em>hardness </em>and <em>luster</em> of the mineral may be used as a basis. For example, the diamond can be determined from the rest of the minerals because it is the hardest and it has a brilliant-kind of luster.
Answer:
The correct order of the elements, taking into account their ionic radius from highest to lowest, is:
<em>a) Cl⁻¹ > F⁻¹ > Na⁺¹ > Mg⁺²</em>
<em>b) S⁻² > O⁻² > Li⁺¹ > Be⁺²</em>
<em>c) S⁻² > Cl⁻¹ > K⁺¹ > Na⁺¹</em>
Explanation:
In ions the ionic radius is determined by the amount of electrons an element gains or loses to become an ion. The more negative an ion is, the greater its ionic radius.
As a rule, anions (negative charge) have a larger ionic radius than cations (positive charge), because the loss of electrons means a contraction of the ionic radius, while the gain of electrons means a greater radius.
To determine which ionic radius is greater in anions or cations with the same charge, it must be considered that in the periodic table the ionic radius increases from top to bottom and from right to left.
