A platinum wire is dipped into a strontium nitrate solution. Then inserted into a burner flame, then the strontium atoms emit a characteristic red color. this is an example of how an element can be identified by its unique atomic emission spectrum.

<h3>What is atomic emission spectrum?</h3>

The goal of an atom's electron arrangement is to keep the energy of the atom as low as feasible. An atom's ground state has the lowest energy level of all the atoms. When the energy is applied to those atoms, the electrons take it in and go to a higher energy level. The electrons in atoms have quantized energy levels, which again means that they must transition from one level to another in discrete increments rather than constantly. An atom is said to be in an excited state when its potential energy exceeds that of the ground state. An excited atom is not a stable atom.

LiOH+HBr---&gt; LiBr +h20 If you start with 10.0 grams of lithium hydroxide, how many grams of lithium bromide will be produced?
kicyunya [14]
<span>LiOH+HBr---> LiBr +h20. Moles of LiOH = 10/24 = 0.41moles. According to stoichiometry, moles of LiOH = moles of LiBr = 0.41moles. Therefore mass of LiBr =moles of LiBr x molecular weight of LiBr = o.41 x 87 = 35.67g. Hope it helps </span>

Can the excess reactant control the percentage yield
katrin2010 [14]

Explanation:

when one reactants is in excess, there will always be some left over. The other reactants becomes limiting factor and controls show much of each product is produced.while using excess percentage yields this is at the expense of atom economy.
