Answer:
A) CaF 2 (Calcium Fluoride)
C KBr (Potassium Bromide)
D) Mgl 2 (Magnesium Iodide)
Explanation:
All the above are electrolytes, because of their ability to dissociate/ionize when dissolved. Strong electrolytes completely ionize when dissolved, and not neutral molecules are able to form in the solution. Electrolytes are substances that conduct electric currents as a result of a dissociation into positively and negatively charged particles called ions, which migrate toward and ordinarily are discharged at the negative and positive terminals (cathode and anode) of an electric circuit, respectively.
D - Silicon
This is because Silicon has four electrons as indicated by the group it's in. Chlorine would have 7, Magnesium would have 2, Phosphorous would have 5, and Sulfur would have 6.
Hope this helps!
Answer:
Silicon, Si forms covalent-network solids.
Explanation:
Silicon, Boron and Carbon are the elements that form covalent networks solids: solid materials whose units consists of chains or networks of atoms or molecules covalently bonded together. Silicon, Si has a similar structure to carbon, but not the exact hardness because Si-Si bonds are not as strong as carbon-carbon bonds.
An example of Si covalent compound is silicon dioxide.
Answer: are called
soft drinks are called carbonate drink because they are made when you pressure the drinks with carbon
Explanation:
The number of values greater than or equal to 8 is mathematically given as
x = 27
This is further explained below.
<h3>What is a data set?</h3>
Generally, Simply put, data sets are groups of information. When dealing with tabular information, a data set is analogous to one or more database tables, where each column represents a different variable and each row represents a separate record.
In conclusion, the total amount of numbers that are either more than or equal to 8
Data value 8 is only exceeded by 9, 10, 11, and 12.
- 8 occurs 4 times
- 9 occurs 6 times
- 10 occurs 8 times
- 11 occurs 4 times
- 12 occurs 5 times
Hence
x= 4+6+8+4+5
x = 27
