What is the more concise and useful way of representing chemical equations?

Using symbols without chemical formulae
Using descriptive sentences
Using only words without chemical formulae
Using chemical formulae instead of words (correct)

What does a skeletal chemical equation represent?

A balanced chemical equation
A chemical reaction with unbalanced mass (correct)
A chemical reaction without any reactants or products
A chemical reaction without any mass

How can you determine if a chemical equation is balanced?

By counting the total number of atoms in the equation
By comparing the number of atoms of each element on the LHS and RHS of the arrow (correct)
By comparing the length of the equation on both sides
By checking if the equation contains all the elements

Explain the basis for classifying elements as metals or non-metals and provide examples of their uses in daily life.

Elements can be classified as metals or non-metals based on their properties. Metals such as iron, copper, and aluminum are used in construction, electrical wiring, and food packaging, while non-metals like sulfur and carbon are used in matches, plastics, and fertilizers.

What properties are considered when categorizing elements as metals or non-metals and how are these properties related to their uses?

Properties such as luster, malleability, and electrical conductivity are considered when categorizing elements as metals. Non-metals are characterized by properties such as dullness, brittleness, and poor electrical conductivity. These properties determine the usefulness of metals in applications such as construction, electrical wiring, and machinery, and the usefulness of non-metals in applications such as insulation, packaging, and agriculture.
