<u>Answer:</u> The given number in scientific notation is
<u>Explanation:</u>
Scientific notation is the notation where a number is expressed in the decimal form. This means that the number is always written in the power of 10 form. The numerical digit lies between 0.1.... to 9.9.....
If the decimal is shifting to right side, the power of 10 is negative and if the decimal is shifting to left side, the power of 10 is positive.
We are given:
A number having value = 0.000000093425
Converting this into scientific notation, we get:
Hence, the given number in scientific notation is
The given question is incorrect, here is a complete question.
Given the equation representing a reaction:
Which statement describes the energy changes that occur in this reaction?
(1) Energy is absorbed as bonds are formed, only.
(2) Energy is released as bonds are broken, only.
(3) Energy is absorbed as bonds are broken, and energy is released as bonds are formed.
(4) Energy is absorbed as bonds are formed, and energy is released as bonds are broken.
Answer : The correct option is, (3) Energy is absorbed as bonds are broken, and energy is released as bonds are formed.
Explanation :
Bond energy : It is defined as the amount of energy required to break a molecules into its component atoms.
At the time of bond formation, the energy is released and at the time of bond breaking, the energy is absorbed.
In the chemical reaction, when the energy is shown in product side that means the energy is released.
In the chemical reaction, when the energy is shown in reactant side that means the energy is absorbed.
Hence, the correct option is, (3)
