Final answer:
There are 6 oxygen atoms in each formula unit of calcium bicarbonate (Ca(HCO3)2), with each bicarbonate ion contributing three oxygen atoms. Option A: 6.
Step-by-step explanation:
The chemical formula for calcium bicarbonate is Ca(HCO3)2. To determine how many oxygen atoms are in each formula unit of calcium bicarbonate, we need to look at the formula and count the number of oxygen atoms within the bicarbonate ions (HCO3-). Since there are two bicarbonate ions, each containing three oxygen atoms, we multiply 3 by 2, which gives us 6 oxygen atoms in one formula unit of calcium bicarbonate.
The correct answer to the question of how many oxygen atoms are present in each formula unit of calcium bicarbonate is
The chemical formula for calcium bicarbonate is Ca(HCO3)2.
To determine the number of oxygen atoms in each formula unit of calcium bicarbonate, we need to look at the structure of the compound. Each HCO3 group contains 3 oxygen atoms, so to calculate the total number of oxygen atoms, we multiply the number of HCO3 groups by the number of oxygen atoms in each group. In this case, we have 2 HCO3 groups, so the total number of oxygen atoms is 2 × 3 = 6.
Therefore, the correct answer is A. 6.
