-what would happen if there was no gravity
okay this is all I could think of
pls mark me as brainlist
The empirical formula can be C₄H₈ or CH₃-CH=CH-CH₃.
Explanation:
As the number of moles of each element is already given ,then there is no need of further calculations. We can get the empirical formula by writing the moles of each element in its subscript position. As empirical formula is one of the simplest way to represent any chemical compound. So the given compound can be written as CₓHₙ. Here x and n are the number of moles of carbon and hydrogen present in the compound.
Since it is stated as the 4 moles of Carbon and 8 moles of hydrogen is present and it is known that each carbon can have maximum four single bond with its neighbors, so the empirical formula can be written as
C₄H₈ or CH₃-CH=CH-CH₃
Thus, the empirical formula can be C₄H₈ or CH₃-CH=CH-CH₃.
In the first chart (NH4)2SO4
Nitrogen is 2
Hydrogen is 8 (h4*2)
Sulfur is 1
Oxygen is 4
For the second chart
Nitrogen i believe is 2
Hydrogen would be 10
Sulfur would should 1
and Oxygen should be 4
Answer:
In first shell duplet rule is applied because first shell contains maximum 2 electrons
Explanation:
<span>The number of atoms in 4.75 moles of gold (Au) is found using Avogadro's number, which is 6.022Ă—1023 mol-1. Determine the number of atoms by multiplying 4.75 moles by Avogadro's number. The number of atoms in 4.75 moles of gold is 2.8605172125000205e24.</span>
