Is LiBr Metal?
Li is Metal why Br is Non Metal
How many atoms are present in 27.0 g Li?
1 mole Li = 6.94g Li = 6.022 x 1023 atoms Li 27.0g Li x 6.022 x 1023 atoms Li/6.94g Li = 2.34 x 1024 atoms Li
What does the chemical symbol for Li mean?
lithium is Li
What is the mass in grams of 2.56 x 10.24 atoms Li?
2.59 atoms?? Oh well. 2.59 atoms Li (1mol Li/6.022 X 10^23 )(6.941 grams Li/1mol Li ) = 2.98 X 10^-23 grams
What is the noble-gas notaion Li and the period in which it belongs?
The noble gas notation for Li is: Li+ . This is because Li, lithium, has one valence electron and must "loose" it to have a full outer shell, like those of the nobel gasses. Li is in period 2 of the periodic table.
What is the symbol of cation of LiBr?
Lithium bromide (LiBr) is a compound, not a cation. The cation is Li+.
1 Lithium reacts spontaneously with Bromine to produce Lithium bromide Write the balanced chemical equation for the reaction If 25.0 g of Lithium and 25.0 g of Bromine are present at the beginning?
2 Li + Br2 = 2 LiBr is the balanced reaction eq'n. For the second part you need to calculate the moles. moles(Li) = 25 / 7 = 3.57 moles(Br2) = 25 / )80 x 2) = 0.15 BY mathematical equivalence of the reaction eq'n 2:1::2 = 0.3:0.15 :: 0.3 So only 0.3 moles (LI) will be reacted, leaving ( 3.57 - 0.3 = 3.27 moles) unreacted. ( That 22.85 g lithium unreacted) It will give a product mass of 7.2 g (LiBr)
What is the oxidation number for LiBr?
+1 for Li -1 for Br
Is LiBr Metal?
Li is Metal why Br is Non Metal
The formula for lithium bromide is?
The formula for lithium bromide is LiBr. The compound has a molar mass of 86.845 grams per mole. One of its main uses is as a desiccant.
What is the chemical equation reaction for lithium metal and bromine gas?
Lithium metal when burned in air would form Lithium Oxide.2Li (s) + O2 (g) --> Li2O (aq)
Is LlBr covalent or ionic?
LiBr lithium bromide is ionic, consisting of Li+ and Br- ions
When 7.6 grams of LiBr is dissolved how many moles of cation are produced?
(7.6g LiBr)/(86.84g/mol) x (1molLi/1molBr) = .0875 mol Li or with sig figs, .088
How do you draw the ionic compound LiBr?
That would be: Li+ bonded via the 'Shared Electron Pair' with Br-; or Li+Br-. Linus Pauling was the originator of the Shared Electron Pair concept!
What is the mass in grams of 3.50mol LiBr?
step 1: calculate the molar mass of one molecule LiBr by adding together their amu (atomic mass units) step 2: 3.50 mol * ( molecular mass LiBr / 1 mol LiBr ) = grams LiBr amu on your periodic table is grams when you have one mol of that substance
What is the correct formula for a lithium ion and bromine ion compound?
Lithium ion is Li+ and a bromine ion (called a bromide ion) is Br- and the compound formed from them would be LiBr.
What are the spectator ions in the neutralization of lithium hydroxide with hydrobromic acid?
Hi, the spectator ions are the ones that are still present (unchanged) at the end of the reaction, in this case its the hydrogen and hydroxyl ions (H+ and OH-) The reaction can be written to show these combined to ake a water molecule but that's only done for neatness. the reaction is better written as; (Li+) + (-Br) + (H+) + (-OH) ---> LiBr + (H+) + (-OH) or; Li+ + -Br ----> LiBr Hope this helps, Mike.
