A compound is a combination of a different elements to form a new substance. The new substance may well have different properties to that of the composing elements. When a compound is made of 50% sulphur and 50% oxygen, it's empirical formula is SO (sulphur oxide). In other words, there is one sulphur atom and one oxygen atom - each consists of 50% of the overall molecule.
The choices can be found elsewhere and as follows:
A.) a definite shape and a definite volume
B.) a definite shape but no definite volume
C.) no definite shape and no definite volume
I believe the correct answer is option C. Two basic properties of the gas phase would be it has no definite shape and no definite volume. It takes the shape and volume of its container. Hope this answers the question.
Answer:
percentage composition of O in HClO IS 30.47
Explanation:
percentage composition of oxygen in HClO =(atomic mass of O)/(atomic mass of HClO)×100
=
=30.47
<h3><u>Answer;</u></h3>
only in the n = 3 energy level
<h3><u>Explanation;</u></h3>
- <em><u>The atom of a chemical element is made up of sub-atomic particles which are the neutrons, protons and electrons.</u></em> The neutrons and protons occupies the nucleus of an atom while the electrons occupy the energy levels.
- <em><u>The first energy level (n=1) of an atom occupies a maximum of two electrons because it has only an S-orbital which can only have two electrons.</u></em>
- <u>The second energy level (n=2) can have a maximum number of 8 electrons, since it contains, one S- orbital which can hold two electrons, and a p-orbital which can accommodate six electrons.</u>
- <em><u>The third energy level (n=3) can have a maximum number of 18 electrons,</u></em> because it has <u><em>the S-orbitals which holds 2 electrons, the p-orbital which holds 6 electrons and the d-orbital which holds 10 electrons. </em></u>
