Does the lithium get heavier after the reaction with oxygen?
When lithium reacts with oxygen, the mass of the lithium is unchanged. However, the mass of lithium oxide (Li2O) created is about 2.1 times as great as the starting mass of lithium metal (110% increase), due to the addition of oxygen. If the lithium reacts with nitrogen, the mass of lithium is similarly unchanged. The reaction produces lithium nitride (Li3N), with a mass about 1.7 times as great as the starting mass of lithium metal (67% increase), due to the addition of nitrogen.
Use the periodic table to answer this question. Decomposing calcium carbonate yields calcium oxide and carbon dioxide. What information is needed to calculate the mass of calcium oxide that can be pro?
To calculate the mass of calcium oxide produced from the decomposition of calcium carbonate, you need the molar masses of calcium carbonate (CaCO₃) and calcium oxide (CaO). Additionally, you must know the amount (in grams or moles) of calcium carbonate you are starting with. Using stoichiometry from the balanced chemical equation, you can determine the mass of calcium oxide that can be produced.

"The amount of grams in one mole a substance" is themolar mass (the mass of 1 mole) of a substance.The molar mass of Lithium oxide (Li2O) is 29.881 g/molThe molar mass of a compound can be calculated by adding the molar masses of the compound's constituent elements.In this case :molar mass of lithium oxide= 2x(molar mass of lithium)+ (molar mass of oxygen)= 2x(6.941) + 15.999=29.881 g/molNotes:* the molar masses of elements are found in the periodic table. * Notice the subscript "2" in the chemical formula of lithium oxide , Li2O. This subscript indicates that two lithium atoms are involved in each lithium oxide atom.Hence, we multiply the molar mass of of lithium by "2" when calculating lithium oxide's molar mass.

To calculate the mass of calcium oxide that can be produced from 4.7 kg of calcium carbonate, you need the molar masses of both calcium carbonate (CaCO₃) and calcium oxide (CaO). Additionally, you need to know the balanced chemical equation for the decomposition of calcium carbonate, which is: CaCO₃ → CaO + CO₂.

What is the molar mass of lithium oxide li20?
The chemical formula for lithium oxide is ( \text{Li}2\text{O} ), not ( \text{Li}{20} ). To calculate the molar mass of lithium oxide, you add the molar masses of its components: lithium (Li) has a molar mass of about 6.94 g/mol, and oxygen (O) has a molar mass of about 16.00 g/mol. Thus, the molar mass of ( \text{Li}_2\text{O} ) is ( 2 \times 6.94 , \text{g/mol} + 16.00 , \text{g/mol} = 29.88 , \text{g/mol} ).
What is the molar mass or lithium oxide?
The molar mass of lithium oxide (Li2O) is 29.88 g/mol.
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.

What is the molar mass of lithium oxide Li2O?
Lithium has a molar mass of 6.94 g/mol. Oxygen has a molar mass of 16.00 g/mol. Since Lithium Oxide has 2 Lithium atoms, the molar mass is: (6.94 x 2) + 16.00 = 29.88 g/mol.

What information is needed to calculate the mass of calcium oxide that can be produced frrom 4.7 kg of calcium carbonate?
To calculate the mass of calcium oxide produced from 4.7 kg of calcium carbonate, you need to know the molar mass of calcium carbonate (CaCO3) and calcium oxide (CaO), as well as the stoichiometry of the reaction between these two compounds. This information will allow you to determine the theoretical yield of calcium oxide that can be obtained from the given mass of calcium carbonate.
What mass of calcium oxide is produced by heating 25 moles of calcium carbonate?
The molar ratio between calcium carbonate and calcium oxide is 1:1. So, 25 moles of calcium carbonate will produce 25 moles of calcium oxide. The molar mass of calcium oxide is 56.08 g/mol, so the mass of calcium oxide produced will be 25 moles * 56.08 g/mol = 1402 g.
