Answer:

fe+s is a mixture of iron and sulphur and it can be separated by magnetic separation. But FeS is a compound formed by heating iron and sulphur together.it can't be separated by any method.

Here are some of the differences between a mixture of iron and sulfur, and iron sulfide: the mixture can contain more or less iron, but iron sulfide always contains equal amounts of iron and sulfur. the iron and sulfur atoms are not joined together in the mixture, but they are joined together in iron sulfide.

Iron has a density of 7.9 space straight g divided by cm cubed. How much mass is in a 10 space cm cubed sample of iron? Question

dezoksy [38]

Answer:

79 g

Explanation:

Density (d) of iron = 7.9 g/cm³

Volume of the iron (V) = 10 cm³

Mass of the iron (m) = ?

Solution:

Formula will be used

d = m/V

As we have to find mass so rearrange the above equation

m = dV . . . . . . . . . . . (1)

Put values in above equation 1

m = 7.9 g/cm³ x 10cm³

m = 79 g

So,

mass of iron = 79 g

80g of sodium hydroxide reacts with excess sulfuric acid to produce 142g of sodium sulfate. What mass of sodium hydroxide would

Ostrovityanka [42]

Answer:

Mass of sodium hydroxide needed = 28.2 g

Explanation:

Given data:

Mass of sodium hydroxide = 80 g

Mass of sodium sulfate produced = 142 g

Mass of sodium hydroxide needed = ?

Mass of sodium sulfate produced = 50 g

Solution:

Mass of sodium sulfate produced / Mass of sodium hydroxide = Mass of sodium sulfate produced / x

142 g/ 80 g = 50 g / x

x = 50 g × 80 g / 142 g

x =4000 g/ 142

x = 28.2 g

2. Which of the following expressions is generally used for solubility? (1 point)

miskamm [114]

Answer:

For 2: The correct answer is grams of solute per 100 grams of solvent.

For 3: The correct answer is supersaturated.

For 4: the correct answer is the solubility decreases.

Explanation:

For 2:

Solubility is defined as the property which refers to the ability of the solute that can be dissolved in a solvent. It is defined as the number of grams of solute per 100 grams of solvent.

For 3:

Unsaturated solution is defined as the solution in which amount of solute that is dissolved in the solvent is less.

Saturated solution is defined as the solution in which no more solute can be dissolved in the given amount of solvent.

Emulsion is defined as the dispersion of one liquid in another liquid in which it is not soluble.

Supersaturated solution is defined as the solution in which solvent contains more amount of solute than the required amount. These solutions help in the process of crystallization.

When a crystal is added to a supersaturated solution, more and more particles come out of the solution and this process is known as crystallization.
