Identify the coefficients and subscripts in the following formulas.

The Correct Answer and Explanation is:<\/mark><\/strong><\/p>\n\n\n\n
Section A: Coefficients and Subscripts<\/h3>\n\n\n\n\n
3MgCl\u2082<\/strong><\/li>\n<\/ol>\n\n\n\n
\n
Coefficient:<\/strong> 3<\/li>\n\n\n\n
Subscript for Mg:<\/strong> 1<\/li>\n\n\n\n
Subscript for Cl:<\/strong> 2<\/li>\n<\/ul>\n\n\n\n\n
Subscript for O:<\/strong> 2<\/li>\n<\/ul>\n\n\n\n\n\n\n\n
Explanation <\/h3>\n\n\n\n
In chemical formulas, coefficients<\/strong> and subscripts<\/strong> help us understand how many atoms or molecules are involved in a substance or reaction.<\/p>\n\n\n\n
Coefficients<\/strong> appear in front of the formula. They show how many molecules<\/strong> or formula units<\/strong> of the compound are present. For example, in 3MgCl\u2082<\/strong>, the number 3<\/strong> is the coefficient. This means there are three molecules of magnesium chloride<\/strong>.<\/p>\n\n\n\n
Subscripts<\/strong> are the small numbers written after element symbols within a chemical formula. They show the number of atoms of that element<\/strong> in one molecule or unit<\/strong> of the substance. In MgCl\u2082<\/strong>, the subscript 2<\/strong> after Cl shows there are two chlorine atoms for every one magnesium atom. Magnesium has no subscript, which means there is only one atom of magnesium (subscript of 1 is implied).<\/p>\n\n\n\n
In V\u2082O\u2085<\/strong>, there is no number in front, so the coefficient is considered to be 1<\/strong>. The subscripts 2 and 5 show there are two vanadium atoms and five oxygen atoms in one molecule.<\/p>\n\n\n\n
In 4K\u2082CO\u2083<\/strong>, the coefficient 4 means there are four units of potassium carbonate. The subscripts show two potassium atoms, one carbon atom, and three oxygen atoms in each unit.<\/p>\n\n\n\n
In NaC\u2082H\u2083O\u2082<\/strong>, no coefficient is written, so it is 1. The formula contains one sodium atom, two carbon atoms, three hydrogen atoms, and two oxygen atoms. This compound is called sodium acetate<\/strong>, a common salt in chemistry.<\/p>\n\n\n\n
Understanding coefficients and subscripts is important for balancing equations and calculating quantities in chemical reactions.<\/p>\n\n\n\n<\/figure>\n","protected":false},"excerpt":{"rendered":"
