Answer:
7.71 × 10⁻⁴ M/s
Explanation:
The initial rate of the reaction can be expressed by using the formula:
![\dfrac{\Delta [O_2]}{\Delta t}](https://tex.z-dn.net/?f=%5Cdfrac%7B%5CDelta%20%5BO_2%5D%7D%7B%5CDelta%20t%7D)
where the number of moles of O₂ = 
where;
Pressue P = 1.00 atm
Volume V =5.74mL = (5.74 /1000) L
Rate R = 0.082 L atm/mol.K
Temperature = 298 K
= 2.35 × 10⁻⁴ mol
Δ[O₂] = 
Δ[O₂] = 
Δ[O₂] = 0.04626 M
The initial rate =
= 
= 7.71 × 10⁻⁴ M/s

Answer:
Correlation means association - more precisely it is a measure of the extent to which two variables are related. There are three possible results of a correlational study: a positive correlation, a negative correlation, and no correlation.

An electron should emit energy to return to its original energy level from a higher energy level.
<h3>What is an energy level?</h3>
Energy levels (also called electron shells) are fixed distances from the nucleus of an atom where electrons may be found.
The electron absorbs the energy and jumps to a higher energy level. In the reverse process, emission, the electron returns to the ground state by releasing the extra energy that is absorbed.
Hence, an electron should emit energy to return to its original energy level from a higher energy level.
