Assuming the most probable meaning of the symbols in the question in standard typography (which the question input rules do not allow!), the expression is 5 Ca(NO2)2. For this expression, the number of oxygen atoms is the product of the explicit subscript 2 immediately following the oxygen atomic symbol, the explicit subscript 2 immediately following the parentheses within which the polyatomic anion symbol that includes the oxygen atomic symbol is enclosed, and the coefficient 5 preceding the entire compound formula: 2 X 2 X 5 = 20 total oxygen atoms.

How many atoms are shown in formula FeO of iron?
The formula FeO represents one iron (Fe) atom and one oxygen (O) atom, totaling two atoms in the compound.
How is ozone shown?
Ozone is typically represented as O3, indicating that it consists of three oxygen atoms. It can also be depicted using structural formulas or ball-and-stick models in chemistry to show how the atoms are bonded together. In atmospheric sciences, ozone concentrations are often shown on maps using color scales to represent the levels in different regions.
What type of atoms are shown in a skeletal model of an organic molecule?
These are atoms of carbon.
May a molecule contain two atoms of the same element?
Yes, a molecule can contain two atoms of the same element. For example, oxygen gas (O2) is a molecule composed of two oxygen atoms bonded together. In this case, both atoms are of the same element, oxygen.
How many atoms of hydrogen are in one molecule of water-?
The chemical formula for water is H2O. The subscripted "2" indicates that there are two atoms of hydrogen in one water molecule. No subcripted number means there is just one atom in the molecule, meaning there are two hydrogen atoms and one oxygen atom.
Are all atoms shown in condensed formulas?
No, in condensed formulas, only the atoms that are bonded directly to each other are typically shown. Hydrogen atoms bonded to carbon and heteroatoms (like oxygen or nitrogen) are often omitted unless necessary for clarity.
What types of atoms are shown in a skeletal model of an organic molecule?
These are atoms of carbon.
What is the ratio of hydrogen atoms to oxygen atoms to be in a molecule of ice?
The ratio of the number of hydrogen atoms to the number of oxygen atoms in any physical state of water is always 2:1, as shown by the chemical formula of water, H2O.
How many atoms are shown in the formula of lithium hydroxide?
LiOH is made of 3 atoms, one of lithium, one of oxygen, and one of hydrogen.
How many atoms per element does carbon dioxide have?
One molecule of carbon dioxide has one carbon atom and two oxygen atoms, as shown by its chemical formula CO2.
What types of atoms are shown in a skeletal model or an organic molecule?
In a skeletal model of an organic molecule, typically only carbon and hydrogen atoms are shown explicitly. Other heteroatoms like oxygen, nitrogen, and halogens are usually implied at the vertex of lines or bonds in the structure.
How many atoms are shown in formula FeO of iron?
The formula FeO represents one iron (Fe) atom and one oxygen (O) atom, totaling two atoms in the compound.
Why does oxygen have a subscript of 3 in aluminum oxide?
Aluminum loses three electrons to have a full valence shell. Oxygen gains two electrons to have a full valence shell. Aluminum Oxide is shown as Al2O3 because there are three oxygen atoms with a total of 6 gained electrons. Two Aluminum atoms lose 6 electrons and three Oxygen atoms gain six. This is the balance between aluminum and oxygen.
How many bonds shown in Lewis structure of 02?
There are two bonds shown in the Lewis structure of O2, one single bond between the two oxygen atoms. Each oxygen atom satisfies the octet rule by sharing two electrons.
How many atoms of each element are shown in the formula for calcium carbonate?
In the formula for calcium carbonate (CaCO3), there is 1 calcium atom (Ca), 1 carbon atom (C), and 3 oxygen atoms (O).
What do subscripts in chemical equations tell about the equation?
The subscript in the equation tells you how many atoms of that element there are in the reaction. For example: H20 --> H2 + O2 Before the reaction there are 2 hydrogen atoms and 1 oxygen (the subscript 1 isn't shown). After the reaction there are 2 hydrogen atoms and 2 oxygen atoms. Keep in mind that this is a skeleton equation and isn't balanced yet.
