Which grade would u like to begin with? I can probably help with grade 9 Intro to Chemistry and Grade 10 Naming elements and compounds. That's all
The atomic weight of H is 1, O is 16.
There are two of each in a hydrogen peroxide molecule.
(1*2)+(16*2)=2+32
2+32=34
The weight of the whole molecule is 34, and hydrogen makes up 2 of that.
(2/34)*100=0.0588235294*100
0.0588235294*100=5.88235294
The percentage mass of hydrogen in a hydrogen peroxide molecule is 5.88%
Answer:
They have mobile charged particles.
Explanation:
Plasma refers to very hot matter such that the electrons in matter are ripped away from the atoms leading to the formation of an ionized gas.
We know that the carriers of electricity are charged particles. Any state of matter that has an abundance of charge carriers will definitely be a good conductor of electricity.
Therefore, plasmas are good conductors of electricity because they have a lot of mobile charged particles.
Don’t worry, you’re right :)
