Use the IUPAC nomenclature rules to give the name for this compound - SiO2
2 answers:
Answer: Name of the given compound is silicon dioxide.
Explanation:
- Write the name of the cation first. Just write the name of an element which is present as a cation.
- Then write the name the anion. The name of the anion is written as name of the element followed by suffix 'ide' in the end.
- If more than one number of anion is present in the compound then use prefixes as 'mono' for 1 , 'di' for 2 , 'tri' for 3 and so on.
have silicon as cation and two oxygen atom as as anion .So, the name of the of the given compound
is silicon dioxide.

Answer:

C)
Explanation:
For this case we want to create a function like this:
Where Z represent the degrees for the Z scale C the Celsius grades and tha valus a and b parameters for the model.
The boiling point of nitrogen is -195,8 °C
The melting point of iron is 1538 °C
We know the following equivalences:
-195.8 °C = 0 °Z
1538 °C = 1000 °Z
Let's say that one point its (1538C, 1000 Z) and other one is (-195.8 C, 0Z)
So then we can calculate the slope for the linear model like this:
And now for the slope we can use one point let's use for example (-195.8C, 0Z), and we have this:
And if we solve for b we got:
So then our lineal model would be:
Part A
The boiling point of water is 100C so we just need to replace in the model and see what we got:
Part B
For this case we have Z =100 and we want to solve for C, so we can do this:
Part C
For this case we know that
And we can use the result from part B to solve for K like this:
