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.
How many grams does 0.1 moles of lithium weigh?
"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.
Calcium carbonate decomposes into calcium oxide & carbon dioxide Her results:Mass of calcium carbonate before heating = 2.00 g Mass of calcium oxide left after heating = 1.12 g work out the mass of carbon dioxide released during the decomposition?
I am not sure of the answer so can someone help me pls
What substance is remaining when magnesium carbonate powder is heated Also why does the mass change Thanks?
Magnesium oxide. Carbon dioxide is released as agas.

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.

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.
The formula mass of lithium carbonate?
Lithium has 1 positive charge, and carbonate has negative 2 charge. Li+ + (CO32-) Therefore, all you need to do is balance it, you will need 2 Lithiums to balance the negative 2 charge and that's it. Li2(CO3)
What mass of calcium oxide is produced by heating 25 moles of calcium carbonate?

If you heated limestone how would you expect the mass of the limestone to compare with the mass of calcium oxide?
When you heat limestone it becomes calcium oxide but if you mean calcium carbonate then it should go down slightly due to the release of CO2
What is the first basic metal on the periodic table?
You think probable to lithium.
Heated magnesium carbonate breaks down to form magnesium oxide and carbon dioxide. explain how one substance can react to form two new substances while still observing the law of mass conservation?
The mass of magnesium carbonate as reactant is equal to the sum of masses of magnesium oxide and carbon dioxide as products.
