The answer is - ide.
That is how you name the anions in a ionic compound, you replace the ending of the name of the element with ide.
Some examples:
Ionic compound anion name of the anion
NaCl Cl- chloride
KF F- fluoride
NaI I- iodide
CaBr2 Br- bromide
The compound HClO4, when placed in water, will dissociate into the ions, H+ and ClO4-. Therefore, the 2.0 M solution will also form 2.0 M H+. The pH is calculated through the equation,
pH = -log[H+]
Substituting,
pH = -log[2] = -0.3
Thus, the pH of the solution is -0.3.
Answer : The final temperature of the system is,
Explanation :
In this problem we assumed that heat given by the hot body is equal to the heat taken by the cold body.
where,
= specific heat of gold =
Note : Molar heat capacity of gold =
Heat capacity of gold =
= heat capacity of water =
= mass of gold = 13.00 g
= mass of water = 13.00 g
= final temperature of system = ?
= initial temperature of gold =
= initial temperature of water =
Now put all the given values in the above formula, we get:
Therefore, the final temperature of the system is,
