Question

1. using a periodic table, determine how many carbon atoms are in the following equation: 3nahco₃

Explanation:

Step1: Analyze the chemical formula

The formula is $3NaHCO_3$. The sub - script after the element symbol represents the number of atoms of that element in one formula unit. Here, for carbon (C) in $NaHCO_3$, the sub - script of C is 1.

Step2: Consider the coefficient

The coefficient 3 in front of $NaHCO_3$ means there are 3 formula units of $NaHCO_3$. Since each formula unit has 1 carbon atom, the total number of carbon atoms is $3\times1 = 3$.

Answer:

3
