When using the scientific notation system to express large numbers, move the<u> decimal point</u> until <u>one </u>digit(s) remain(s) to the left, then indicate the number of moves of the decimal point as the <u>power of ten.</u>
Explanation:
Scientific notation is the way to express the large value in short form.
The number in scientific notation have two parts.
. The digits (decimal point will place after first digit)
× 10 ( the power which put the decimal point where it should be)
for example the number 6324.4 in scientific notation will be written as = 6.3244 × 10³

because it says when ever air hits the iron it reacts so if we make a slower release then it will take less time to get cold !
An ionic bond is a bond which occurs when there is a

atom hence making it more negative (anion), while the other becomes a cation.
So answer is:
