Answer:
A. AlO
Explanation:
The empirical formula of a compound is the simplest possible formula giving the ratio of atoms in a molecule of the compound.
We know that Aluminium forms 
and oxygen forms 
.
As such the formation of the ionic compound between a metal and non-metal results into 
.
The empirical formula is as follows:
Element Aluminium Oxygen
% composition
by mass 26.98 16.0
mole ratio 26.98/26 16/16
= 1.04 = 1
divided by the
smallest number 1.04/1 1/1
1.04 1
The empirical formula is AlO
Answer:
Explanation:
Hello,
In this case, since the carbon of the initial compound is present in the carbon dioxide product, we can compute the mass and moles of carbon in the compound:
Next, the mass and moles of hydrogen in the compound, is contained in the yielded amount of water, thus, we compute the mass and moles of hydrogen in the compound:
In such a way, the mass of oxygen comes from the mass of the compound minus the mass of carbon and oxygen:
And the moles:
Then, we compute the subscripts by diving the moles of C, H and O by the moles of oxygen as the smallest moles:
After that, we write:
Which must be shown in whole number only, thereby we multiply the subscripts by 2, so the empirical formula turns out:
Best regards.
Answer:
Chicken noodle soup would be considered a mixture.
Answer:
Tetrahedral, sp3, p
Explanation:
C has 4 bonds and hence its tetrahedral shape with 109.5 degrees. since there are 4 bonds, it is sp3
Non of them seem right... but I think C could be correct cause it definitely cant be A.
