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: 598.9K = 325.9°C
Explanation:
P1= 53.3kPa T1= -33+273=240K
P2=133kPa , T2= ?
Applying P1/T1 = P2/T2
Substitute and Simplify
53.3/240 = 133/T2
T2= 598.9K = 325.9°C
Answer:
Explanation:
A new Material is formed.
Basically, Chemical changes differ from Physical changes because in chemical changes, Substances have the ability to become a different substance.
Example:
Water to ice is a physical change because it is still water despite being a solid from liquid.
A Magnesium strip placed in CuSO4 solution made the Mg strip turn into a new substance which is MgSO4. this is a Chemical change because Mg has now become a different substance called MgSO4.
This is genetic engineering.
I hope this helps!
