A graduated cylinder contains 20.8 mL of water. What is the new water level, in milliliters, after 35.2 g of silver metal is sub

stepladder [879]

Answer: The new water level of the cylinder is 24.16 mL

Explanation:

To calculate the volume of water displaced by silver, we use the equation:

$\text{Density of substance}=\frac{\text{Mass of substance}}{\text{Volume of substance}}$

Density of silver = 10.49 g/mL

Mass of silver = 35.2 g

Putting values in above equation, we get:

$10.49g/mL=\frac{35.2g}{\text{Volume of silver}}\\\\\text{Volume of silver}=\frac{35.2g}{10.49g/mL}=3.36mL$

We are given:

Volume of graduated cylinder = 20.8 mL

New water level of the cylinder = Volume of graduated cylinder + Volume of water displaced by silver

New water level of the cylinder = (20.8 + 3.36) mL = 24.16 mL

Hence, the new water level of the cylinder is 24.16 mL

When preparing the diazonium salt, the solution is tested with potassium iodide-starch paper. a positive test is the immediate f

Dahasolnce [82]

KI-starch paper allows the detection of strong oxidizers such as nitrite. It is used here to control diazotization of 4-nitroaniline. Nitrite oxidizes potassium iodide in order to form elemental iodine which reacts with starch to a blue-violet complex. With KI-starch paper, enough sodium nitrite is added to produce nitrous acid, which then will react with 4-nitroaniline to form a diazonium salt.

What is the most soluble salt of the following set? What is the most soluble salt of the following set?

DiKsa [7]

Answer:

Explanation:

The solubility product of a solid is the amount of solid dissociates into its respective ions in the solution. Thus more the value of the Ksp, the more is the salt soluble in the solvent.

So, Given that:-

$Sn(OH)_2\ (K_{sp} =1.6\times 10^{-19})$

$Al(OH)_3\ (K_{sp} =1.9\times 10^{-33})$

$AgCN\ (K_{sp} =6.0\times 10^{-17})$

$Fe(OH)_3\ (K_{sp} =2.6\times 10^{-39})$

The salt having highest value of Ksp is AgCN. So, it is most soluble.
