727,000 in scientific notation is written as 7.27 * 10^5
The decimal or whole number must be between 1 and 10. Then, what I do, is count the amount it takes me to get to 7.27, which, in this case, is 5
Hope that answered your question!
When titrating a strong monoprotic acid and KOH at 25 degrees Celcius, the pH will be approximately equal to 7.00. Since a strong acid and a strong base reacts through a neutralization reaction. The pH of a neutral solution is 7.00. <span />
There are 4 things that are evidence of a chemical change.
1)Change in color
2)Change in shape (gas being let out)
3)Change in temperature
4)Change in smell
Burning wood is a chemical change because it has a change in color, and shape.
The atomic number of Fe= 26
The electronic configuration of Fe will be
1s2 2s2 2p6 3s2 3p6 4s2 3d6
When it loses two electrons to form ferrous ion (Fe(II)) the electrons will be loose by 4s orbital first
So the electronic configuration of Fe^+2 ion will be
1s2 2s2 2p6 3s2 3p6 3d6
Hence there are six electrons in 3d orbital of iron dipositive ion
Now the the electrons in 3d orbital will be like:
so there are four unpaired electrons
