8 0

You could identify a physical property of a substance before you performed the activity because the characteristics of a material known as its physical qualities are those that may be investigated independently of the substance's chemical makeup.

This is further explained below.

<h3>What is physical property?</h3>

Generally, Any attribute that can be measured and has a value that can be used to describe the state of a physical system is considered to be a physical property.

In conclusion, The changes that take place in a system's physical attributes may be utilized to provide a description of the transitions that take place between its momentary states.

Ferrous sulfate (FeSO4) was used in the

BARSIC [14]

Ferrous sulfate (FeSO4) is obtained by the reaction of aqueous ferric sulfate with gaseous sulfur dioxide and water according to the equation below:

Aqueous ferric sulfate = $Fe_2(SO_4)_3_{(aq)}$

Gaseous sulfur dioxide = $SO_2_{(g)}$

Water = $H_2O_{(l)}$

Aqueous sulfuric acid = $H_2SO_4_{ (aq)}$

Aqueous ferrous sulfate = $FeSO_4_{ (aq)}$

Thus, the balance equation becomes:

$Fe_2(SO_4)_3_{(aq)}$ + $SO_2_{(g)}$ + $2H_2O_{(l)}$ $--->$ $2 H_2SO_4_{ (aq)} + 2 FeSO_4_{ (aq)}$

2Fe +3S= Fe2S3 how many grams of sulfur are involved in this reaction if 95 grams of iron are needed to react with sulfur

Zepler [3.9K]

Answer:

83 g

Explanation:

Step 1: Write the balanced equation

2 Fe + 3 S ⇒ Fe₂S₃

Step 2: Calculate the moles corresponding to 95 g of Fe

The molar mass of Fe is 55.85 g/mol.

95 g × 1 mol/55.85 g = 1.7 mol

Step 3: Calculate the moles of S needed to react with 1.7 moles of Fe

The molar ratio of Fe to S is 2:3. The moles of S needed are 3/2 × 1.7 mol = 2.6 mol

Step 4: Calculate the mass corresponding to 2.6 moles of S

The molar mass of S is 32.07 g/mol.

2.6 mol × 32.07 g/mol = 83 g

Which is a chemical change?

OverLord2011 [107]

A chemical change alters the chemical makeup of a substance. So, wood burning would be a chemical change. The others just alter the physical makeup of the substance.
