MnO_2 To write the chemical formula for Manganese (IV) Oxide, you must make sure to balance the charges. The roman numeral IV in front of manganese tells us that it is oxidizing at 4^+. Looking at the table, oxygen is a group 16 element which means it oxidizes at a 2^- state, To neutralize the oxidation number of manganese, two atoms of oxygen should be added to achieve the final compound MnO ...
Explanation: Barium is an alkaline earth metal, and forms Ba2+ ions; nitrogen is from Group 15, and can form nitride ions, N 3−. The salt that forms will be electrostatically neutral, so a formula of Ba3N 2. Charge is balanced. Ba_3N_2 Barium is an alkaline earth metal, and forms Ba^ (2+) ions; nitrogen is from Group 15, and can form nitride ...
Explanation: Graphite is simply an allotrope of carbon, and therefore only contains carbon atoms in its chemical formula. Its structure looks like this: Just repeating units of carbon atoms (C). Graphite is simply an allotrope of carbon, and therefore only contains carbon atoms in its chemical formula. Its structure looks like this:
The balanced chemical equation is: Mg_ ( (s))+ 2HCl_ ( (aq))rarrMgCl_ (2 (aq)) + H_ (2 (g) The reaction between magnesium and hydrochloric acid combine to form a salt of magnesium chloride and release hydrogen gas. This single replacement reaction is a classic example of a metal reacting in an acid to release hydrogen gas. I hope this was helpful.
A diamond consists of a giant three-dimensional network of carbon atoms. In effect, a diamond is one giant molecule. All we can do is write its empirical formula, which is C. The answer is simple: "C". Diamond is one form of carbon; the other is graphite. To distinguish them, we write: diamond: C (s,diamond) graphite: C (s,graphite) The s ...
ZnBr_2 The zinc ion will have a charge of +2 and the bromide ion has a charge of -1 because it is a halogen. Combining the ions in a 1:2 ratio produces a compound which is electrically neutral. Zinc can sometimes have other oxidation states (+1 for example) but these are pretty rare... This video discusses some more examples of how to figure out a formula for a compound from its name or vice ...
This represents the element aluminum in its metallic form, which is what aluminum foil is made of. Alumina is synthetic aluminum oxide of the molecular formula Al2O3. It is used in the smelting of ...
"Na"_3"N" Sodium is an element in group 1 of the periodic table. As such, it will form an electron by losing a single electron to form a "1+" ion: "Na"^+. Nitrogen is an element in group 5 of the periodic table. When it forms the nitride ion, it gains three electrons to form a "3-" ion: "N"^(3-). In ionic compounds, the charges of constituent ions must balance. This can be achieved by having ...
The formula for calcium fluoride is "CaF"_2". An ionic compound is neutral, which means its overall charge is zero. Therefore, the sum of the charges of each ion in the compound must equal zero. In calcium fluoride, the calcium ion "Ca"^(2+)", has a charge of 2+, and the fluoride ion "F"^(1-)" has a charge of 1-. We will need two fluoride ions to make the overall charge zero. "Ca"^(2+)"+ 2F ...
C_5H_7N is the empirical formula of nicotine. It tells that in one molecule of nicotine there are 5 atoms of carbon for each 7 atoms hydrogen and 1 atom of nitrogen. C_10H_14N_2 is the molecular formula of nicotine. It provides the ratio of atoms of each of the elements present 5:7:1 it also provides the actual number of atoms.
