A. Of a given element have different numbers of neutrons
An orbital is the most probable location of an electron. This is because you can't pinpoint the exact location of an electron because as soon as you do it will have moved again, so orbitals are used to find the probability of where a certain electron is.
Answer:
Explanation:
Given parameters:
Number of breathe per minute = 15times
Volume of air per breath = 0.5L
Percentage of oxygen in air = 21%
Solution
There are 24 hours in a day.
60minutes makes a hour in a day,
I will breathe:
15 times x 60 x 24 = 21600 times in a day
The volume of air I will take in per day:
A breathe = 0.5L of air
21600breathe = 0.5 x 21600 = 10800L of air
Volume of oxygen I will breathe per day:
x 10800 = 2268L of oxygen
