The compound Ca(CIO3)2 consists of one calcium (Ca) atom, two chlorine (Cl) atoms, and six oxygen (O) atoms (since each CIO3 group contains one Cl and three O, and there are two such groups). Therefore, the total number of atoms in the compound is 1 (Ca) + 2 (Cl) + 6 (O) = 9 atoms.
Assuming that the compound is the one that should have been written as Ca(ClO3)2, the answer can be determined by counting in a properly interpreted formula: one Ca, two Cl, and six O for a total of nine.
The chemical formula 4NaOC1 represents a compound comprised of sodium (Na), oxygen (O), and chlorine (Cl). In this formula, there are 4 sodium (Na) atoms, 1 oxygen (O) atom, and 1 chlorine (Cl) atom. Therefore, the total number of atoms is 4 (Na) + 1 (O) + 1 (Cl) = 6 atoms.
Chlorine dioxide has a bent shape. It is very interesting in that one Cl-O bond is a double bond, and the other is a single bond with three electrons. Refer to the related links for the Wikipedia article on this compound.
The compound in the group is HCl (hydrochloric acid). Mercury (Hg) is a metal, while O (oxygen) and C (carbon) are nonmetals that do not form a compound with H in the same context as HCl. HCl consists of hydrogen (H) and chlorine (Cl), making it a distinct chemical compound.
+3 for Cr and -2 for O
The aluminum ion is Al3+ and the sulfide ion is S2-. The formula for aluminum sulfide is Al2S3. In an ionic compound, the size of the charge of each ion becomes the subscript on the opposite ion. This is called the crisscross rule. https://www.youtube.com/watch?v=99NVKAss5LE&t=240s
This compound is potassium oxide, K2O.
The compound Ca(CIO3)2 consists of one calcium (Ca) atom, two chlorine (Cl) atoms, and six oxygen (O) atoms (since each CIO3 group contains one Cl and three O, and there are two such groups). Therefore, the total number of atoms in the compound is 1 (Ca) + 2 (Cl) + 6 (O) = 9 atoms.
To balance the formula Cr₂O₃, you ensure that the number of chromium (Cr) and oxygen (O) atoms on both sides of the equation is equal. In Cr₂O₃, there are 2 chromium atoms and 3 oxygen atoms. This compound is already in its simplest form, meaning it cannot be simplified further while maintaining the ratio of chromium to oxygen. Thus, the balanced formula is Cr₂O₃ as it stands.
Chemical formula foe chlorine monoxide is Cl2O. It is made of elements Cl and O. So it is a compound.
H3C is a part of the larger compound H3C-CH2-O-CH3, which is ethyl methyl ether, also known as methoxyethane.
In Na2Cr2O7, sodium (Na) has an oxidation state of +1, and oxygen (O) typically has an oxidation state of -2. Given that the overall compound is neutral, the oxidation state of chromium (Cr) in this case is +6.
Cr2O3 is an ionic compound. It is composed of chromium (Cr) and oxygen (O) ions that are held together by ionic bonds.
The compound calcium chlorate contains the elements calcium (Ca), chlorine (Cl), and oxygen (O).
Assuming that the compound is the one that should have been written as Ca(ClO3)2, the answer can be determined by counting in a properly interpreted formula: one Ca, two Cl, and six O for a total of nine.
