What reagent would distinguish between Ag+ and Fe3+?

Chemistry

The reagent which is used is "NaI", that is Sodium iodide.
When the reagent sodium iodide is added to distinguish the Ag⁺ ions and Fe³⁺ ions, it will react and form precipitate with one, while have no precipitates formed with the other, so that is how we can distinguish both of them.

What is the mass of the hydrogen peroxide that exactly fills a 200.0 mL container? The density of ethyl alcohol is 0.789 g/mL.
Tom [10]

Answer:

290 g of hydrogen peroxide would fill the 200.0 mL container

Explanation:

Given data:

Volume = 200.0 mL  

Mass of hydrogen peroxide = ?

Solution:

Density of hydrogen peroxide is 1.45 g/cm³.

Density:

Density is equal to the mass of substance divided by its volume.

Units:

SI unit of density is Kg/m3.

Other units are given below,

g/cm3, g/mL , kg/L

Formula:

D=m/v

D= density

m=mass

V=volume

Now we can determine the mass of hydrogen peroxide.

D = m/v

1.45 g/cm³ = m/ 200.0 mL

1 mL = 1 cm³

m = 1.45 g/cm³× 200.0 cm³

m = 290 g

So 290 g of hydrogen peroxide would fill the 200.0 mL container.

A gas is initially at a pressure of 225 kPa and a temperature of 245 K in a container that is 4.5 L. If the gas is compressed to
Artyom0805 [142]
Use the ideal gas equation PV=nRT. You can compare before and after using P1V1/n1T1=P2V2/n2T2. Since the number of moles remains constant you can disregard moles from the equation and use pressure, volume and temp. Make sure your pressure is converted to atmospheres, your volume is in liters, and your temperature is in kelvins.

What does the atomic number tell you
rusak2 [61]

Answer:

Explanation:

The atomic number tells you how many protons are in an element. Each element has a different number of protons, so a specific number of protons will also help you easily identify that particular element. For example, if you are given that an element has an atomic number of 1, you would know the element is hydrogen because other elements have different amounts of protons and thus different atomic numbers.
