The slight error has been to use the prefix mono to name monocarbon.

The compound she is most likely naming is:

 CBr_4.

As you see, the chemical formula has 1 atom of C, which is likely why she named it mono, and 4 atoms of Br.

The right name is carbon monobromide, i.e. you have to supress the prefix mono, as per IUPAC rules.

Dafna11 [192]

Answer:

18.18C

Explanation: Write whats below to show your work :D

m=55

C=0.45

Q=450zj

ch.temp=?

Q=mct

450 = (55)(.45)T

450 = 24.75

/24.75 = /24.75 (cancels out)

18.18 is the answer

Hope this helps! did it with my teacher.

If a liquid has a pH of 7 it is what?
sweet-ann [11.9K]

Answer:

Neutral

Explanation:

A pH of 7 is neutral. A pH less than 7 is acidic. A pH greater than 7 is basic. The pH scale is logarithmic and as a result, each whole pH value below 7 is ten times more acidic than the next higher value.

Four acids are analyzed and there KA values are determined which of the following values represents the strongest acid
Advocard [28]

x= the coefficients in front of the substance in the balanced chemical equation  

[H+]= the concentration of hydrogen ions  

[A-]= the concentration of the other ion that broke off from the H+  

[HA]= the un-disassociated acid concentration  

The higher the Ka value, the greater amount of disassociation of the reactants into products. As for acids, they will break down to form H+ ions. The more the H+ ions, the stronger acidity of the solution. Thus since A has the highest Ka value, that represents the strongest acid.  

You can determine the Ka value from a number of ways. If equilibrium concentrations are given of a certain acid solution, you can find the proportion of the concentration of ions to the concentration of the remaining HA molecules, using the equation above. Also, pH and KpH can be used in a number of ways. This gets more complicated and depends on the situation, and requires more advanced equations.


Hope this helped a little, its obviously not my best work
