I attached the full question.
We need to calculate the enthalpy change first:

Keep in mind this is the energy per mole, we need energy per atom:

We can see that this reaction needs the energy to get started (enthalpy change is positive).
The energy of a photon is given with this formula:

We need this photon to have the same energy (or higher) as our enthalpy change:

This wavelenght is clasified as near infrared.
It most likely wont explode right away but the fumes from the heated pickle might put you on a mild high if you breathe it in a lot...

Brainliest pls! thx! :)
To solve this problem we will apply the geometric concepts of the Volume based on the consideration made of the radius measurement. The Volume must be written in differential terms of the radius and from the formula of the margin of error the respective response will be obtained.
The error in radius of sphere is not exceeding 2%

The objective is to find the percentage error in the volume.
The volume can be defined as

Differentiate with respect the radius we have,




The percentage change in the volume is as follows



Therefore the percentage change in volume is 
Answer:
Two or more simple machines work together to form a complex machine. Compound machines can do more difficult jobs than simple machines alone. Examples of complex machines are bicycle, wheel barrow, crane, car jack, lawn mover
