The correct option is D.
Engineers and constructions workers have different types of footwear, which they make use of when they are in the field. Each of these foot wears has its own purpose and functions. For instance, the steel toe boots serve to protect the foot from falling falling objects and also from compression. The foot wear has a protective support in the toe and also possesses a mid sole plate to protect the foot again puncture from the sole.
Answer:
Rows and columns.
Explanation:
Each atom gives up some of its electrons to create a kind of sea of these randomly moving charged particles. It's these free-flowing electrons that make metals conductive.
Answer:
Wurzite has a higher Madelung constant when compared with Sphalerite therefore Wurizite is more stable.
Explanation:
Zinc Sulphide is a chemical compound that exhibits polymorphism. This means Zinc Sulphide can exists in different forms as a compound. Zinc Sulphide has two common polymorphs named; Wurtzite and Sphalerite .
This two polymorphs are crystalline in structure. Wurtzite is hexagonal in shape while Sphalerite is cubic in shape.
Madelung constant was named after German Physicist Erwin Madelung. Madelung constant is dependent on the the way ions are arranged in a solid substance or molecule. It is used to calculate the amount of energy required to move an ion from one point to the another in a crystal substance.
Madelung constant for Wurtzite is 1.64132 and for Sphalerite is 1.63806. Due to the fact that Wurtzite has a slightly higher Madelung constant that Sphalerite, it tends to be more stable than Sphalerite.

Answer:
How many grams of CCL4 were formed? 116.9 g
How many grams of Cl2 reacted with the CH4? 243.8 g
Explanation:
First we need to know the molar mass for every element or compound in the reaction:

Now we proceed to calculate the amount of moles produced, per product:

To calculate the mass of chlorine we just need to make a mass balance:

Answer:
D. Single Displacement
C. More reactive than
Explanation:
Al + CuSO₄ ---> Cu + Al₂(SO₄)₃
The aluminum replaces the copper in the compound, isolating copper. This occurs because the aluminum is more reactive than the copper.
I hope this helps! :)
