If by valences, you mean valence electrons, chromium has 6, lithium has 1, carbon has 4, and sulfur has 6. If by valences, you mean valence electrons, chromium has 6, lithium has 1, carbon has 4, and sulfur has 6.
Yes, it has iron, chromium, carbon and nickel.
Steel by definition is an alloy of iron and carbon, with other possible ingredients as well (nickel, chromium, etc.). It always has both iron and carbon.
No, lithium is in the alkali metals group.
Yes, carbon is more reactive than chromium. Carbon is a non-metal and easily forms compounds with other elements, while chromium is a transition metal that is more stable and less reactive.
Carbon dioxide does not react with lithium under normal conditions. Lithium is a highly reactive metal that can react with water or oxygen to form lithium oxide or lithium hydroxide, but not with carbon dioxide.
Carbon (12) has a higher atomic mass than lithium (7).
lithium carbonate + hydrochloric acid ---> lithium chloride + carbon dioxide + water
Li4C is the chemical formula for lithium carbide, a compound composed of lithium and carbon atoms. It is an ionic compound that is typically synthesized through the reaction of lithium metal with carbon at high temperatures. Li4C is not commonly encountered as it is unstable and generally reactive.
Chromium can combine with various elements to form different compounds. For example, it can combine with oxygen to form chromium oxide, with carbon to form chromium carbide, and with sulfur to form chromium sulfide. Additionally, chromium can also combine with other metals to form alloy compounds.
Lithium is the odd one out because it is a metal, while nitrogen, oxygen, and carbon are nonmetals.
lithium carbonate + sulfuric acid = lituim sulfate + water + carbon dioxide
The chemical formula for chromium III carbonate is Cr2(CO3)3. When it decomposes, it yields chromium III oxide (Cr2O3) and carbon dioxide (CO2).
