Answer:

D.

Explanation:

Hard to explain.

Just write out original and work with individual variables each. Balance aluminum first and then use LCM for oxygen and rebalance aluminum.

What is the Chemical Structure of Solids, Liquids and Gases?
postnew [5]

Gas --> separated particles, usually a great amount away from each other

Liquids --> particles are closer together but not always touching

Solids --> particles are solidly packed together, not one is distant

hope this helped, have a fantastic night/day/morning :)

The H atom and the Be3³⁺ ion each have one electron. Does the Bohr model predict their spectra accurately? Would you expect thei
lbvjy [14]

Explanation:

a) Bohr model is perfect for atoms that have single electron and fortunately both Be3+ ion and H atom have one electron so, Bohr model can easily and accurately applied to predict the spectrum of Be3+ and H atom.

b) The energy of an atom in  Bohr model is given by

E= \frac{-13.6z^2}{n^2}

the values of z for H atom and Be3+ ion are 1 and 4 respectively. Hence, energy of atoms would be different for both atoms. Hence, line spectra to be identical is not possible.

Use the unbalanced equation NH3 + O2 = NO + H2O, what is the mole ratio between NH3 and NO
kirill115 [55]
<span>The first thing that needs to be done in order to answer the question above is to balance first the chemical equation by seeing to that the number of moles of a certain element on the reactant side is equal to the number of moles in the product side. 4NH3 + 5O2  4NO + 6H2O The mole fraction between the NH3 and NO is therefore 4:4 or 1:1.</span>
