If lithium carbonate contains 18.8 percent lithium. What mass of lithium is present in a 1.55g of lithium carbonate?
To work out the mass of one element within a compound (ie the mass of Lithium in Lithium Carbonate), first work out the RFM (Relative Formula Mass) of the compound. To do this, look on the periodic table (PT) & add up the RAM (Relative Atomic Mass) of all of the atoms in the compound (the RAM is the larger of the 2 numbers in each box on the PT). So, if the formula for one molecule of Lithium Carbonate is Li2CO3, then the RFM is Li + Li + C + O + O + O = 7 + 7 + 12 + 16 + 16 + 16 = 74 Next work out what percentage of the compound is the element you want to know. So, Lithium accounts for 14 (2 Lithiums = 7 x 2) out of every 74 grams of Lithium Carbonate. As a percentage, this is ( 14 / 74 ) x 100 = 18.9 %. So, 18.9% of 1.55g [ ( 1.55 / 100 ) x 18.9 ] = 0.29g So there is 0.29g of Lithium is 1.55g of Lithium Carbonate.
Why is lithium hydroxide and lithium carbonate the least soluble hydroxide and carbonate among group1 metal hydroxides and carbonates?
Lithium hydroxide and carbonate are the least soluble among group 1 metal hydroxides and carbonates because of the small size of the lithium ion. This small size leads to higher lattice energies, making it more difficult for water molecules to break the ionic bonds and dissolve the compounds. Additionally, lithium ions have a high charge density, which further stabilizes the solid state of lithium hydroxide and carbonate.
What is the blanced equation for lithium carbonate and iron II iodide?
Lithium carbonate + Iron(II) iodide ----> Lithium iodide + Iron(II) carbonateLi2CO3 + FeI2 ----> 2 LiI + FeCO3
What are other names for lithium?
Lithium is sometimes known as Li in the periodic table or as "lithia" when referring to lithium compounds. It is also commonly referred to by its chemical name, lithium carbonate, in pharmaceutical contexts.
What is the net ionic equation for the reaction of barium nitrate and lithium carbonate?
The net ionic equation for the reaction of barium nitrate and lithium carbonate is Ba^2+ + CO3^2- -> BaCO3. This is because barium forms a white precipitate of barium carbonate when it reacts with carbonate ions, and lithium ions do not participate in the formation of the precipitate.
What is the name for Li2O?
lithium hydroxide + carbon dioxide --> lithium bicarbonate
What happen when lithium carbonate is heated?
Lithium carbonate is thermally decomposed by heating.
What is the word equation for the reaction of lithium carbonate and hydrochloric acid?
lithium carbonate + hydrochloric acid ---> lithium chloride + carbon dioxide + water
What ionic compound is Li2CO3?
Lithium carbonate is the ionic compound with the formula Li2CO3. It is composed of lithium ions (Li+) and carbonate ions (CO3^2-).
What is the word equation for lithium carbonate and sulfuric acid?
lithium carbonate + sulfuric acid = lituim sulfate + water + carbon dioxide
Is lithium carbonate molecular or ionic?
Lithium carbonate is ionic because it is composed of lithium cations (Li+) and carbonate anions (CO3^2-). These ions are held together by ionic bonds, which involve the transfer of electrons between the lithium and carbonate atoms.
What is the formulae of lithium hydroxide?
LiOH
Why carbonate of lithium is not stable?
Lithium carbonate is generally stable, but it can react with acidic solutions to form lithium ions, which are water-soluble. This can lead to the gradual decomposition of lithium carbonate over time in the presence of moisture or acids. Additionally, lithium carbonate can absorb carbon dioxide from the air, forming lithium bicarbonate, which can further contribute to its instability.
What is the balanced equation of lithium carbonate?
The balanced equation for lithium carbonate is Li2CO3.
If a patient takes a 300mg lithium carbonate capsule how much elemental lithium is taken?
A 300mg lithium carbonate capsule contains about 112mg of elemental lithium.
What is Chemical identification test of lithium carbonate?
One common chemical identification test for lithium carbonate is the flame test. When lithium carbonate is heated in a flame, it produces a characteristic crimson red color. This color is distinctive for lithium ions and can be used to confirm the presence of lithium in a sample.
Is Lithium Hydrogen Carbonate's formula LiHCO3?
No, the formula for lithium hydrogen carbonate is LiHCO3. Lithium carbonate has the chemical formula Li2CO3.
