The reaction that results in the formation of a solid should be identified. Concept Introduction: A balanced chemical equation is an equation that contains same number of atoms as well as of each element of reactants and products of reaction. For example, the reaction between lead sulphide and oxygen is as follows: 2 PbS+3 O 2 → 2 PbO+ 2 SO 2 Reactants Products In the given reaction, the number of all atoms, on the both side are equal hence this is a balance reaction. The most common driving forces which create product in chemical reactions are as follows: Formation of a solid. Formation of water. Transfer of electrons. Formation of gas. If a substance is not soluble in water than it forms precipitate. The phase of the precipitate is solid. The precipitates are formed depending on the solubility of salt in water.

Interpretation Introduction

Interpretation:

The reaction that results in the formation of a solid should be identified.

Concept Introduction:

A balanced chemical equation is an equation that contains same number of atoms as well as of each element of reactants and products of reaction.

For example, the reaction between lead sulphide and oxygen is as follows:

2 PbS+3 O2→2PbO+2SO2 Reactants Products

In the given reaction, the number of all atoms, on the both side are equal hence this is a balance reaction.

The most common driving forces which create product in chemical reactions are as follows:

Formation of a solid.

Formation of water.

Transfer of electrons.

Formation of gas.

If a substance is not soluble in water than it forms precipitate. The phase of the precipitate is solid. The precipitates are formed depending on the solubility of salt in water.

Learning Goal: This question reviews the format for writing an element's written symbol. Recall that written symbols have a particular format. Written symbols use a form like this: 35 Cl 17 In this form the mass number, 35, is a stacked superscript. The atomic number, 17, is a stacked subscript. "CI" is the chemical symbol for the element chlorine. A general way to show this form is: It is also correct to write symbols by leaving off the atomic number, as in the following form: atomic number mass number Symbol 35 Cl or mass number Symbol This is because if you write the element symbol, such as Cl, you know the atomic number is 17 from that symbol. Remember that the atomic number, or number of protons in the nucleus, is what defines the element. Thus, if 17 protons are in the nucleus, the element can only be chlorine. Sometimes you will only see 35 C1, where the atomic number is not written. Watch this video to review the format for written symbols. In the following table each column…
