It means it’s neutrally charged! Protons are positive while electrons are negative, so they balance each other out. Neutrons are neutral so they don’t weigh in.
Can you post the question
oops pls forgive me I accidentally did the wrong question.
Are u sure this is the right option? Well, antimony can be decomposed. Including octane.
Answer:
See Explanation
Explanation:
The question is incomplete; as the mixtures are not given.
However, I'll give a general explanation on how to go about it and I'll also give an example.
The percentage of a component in a mixture is calculated as:

Where
E = Amount of element/component
T = Amount of all elements/components
Take for instance:
In 
The amount of all elements is: (i.e formula mass of
)



The amount of calcium is: (i.e formula mass of calcium)



So, the percentage component of calcium is:




The amount of hydrogen is:



So, the percentage component of hydrogen is:




Similarly, for oxygen:
The amount of oxygen is:



So, the percentage component of oxygen is:
