Answer:
a) V air/day = 8640 L air an adult breaths / day
b) 0.0181 L CO intake a person / day
Explanation:
a) one average person has 12 breaths for min:
in each breath it take an average of 500 mL on air.
⇒ 12 breath / min * 500mL air / breath = 6000 mL air / min
the average air volume per day of a person is:
⇒ Vair/day = 6000 mL air / min * (60 min / h) * ( 24 h / day ) = 8640000 mLair / day * ( L / 1000 mL)
⇒ V air / day = 8640 L / day
b) 2.1 E-6 L CO / L air * 8640 L air / day = 0.0181 L CO / day

Explanation:
Population change is governed by the balance between birth rates and death rates. If the birth rate stays the same and the death rate decreases, then population numbers will grow. If the birth rate increases and the death rate stays the same, then population will also grow.

Explanation:
Hello,
In this case, given that 1 kilometer equals 1000 meters, 1 meter equals 3.281 feet and 1 hour equals 3600 seconds, the required velocity in feet per second turns out:
Regards.
Electrolysis is a process, which allows us to break down a chemical compound into its elements, completing the balance by adjusting the number of atoms on both sides of the reaction is important because the number of electrons given up during oxidation must be the same as the number of electrons gained during the reduction.
<h3>What is electrolysis of water?</h3>
It is a process of oxidation and reduction of one or more elements that, through the induction of electric current, breaks down the water molecule (H2O), thus producing gaseous hydrogen and oxygen.
Oxidation and reduction processes occur simultaneously and never in isolation, which is why they are called redox reactions.
Therefore, we can conclude that electrolysis is a process where electrical energy will change to chemical energy where it is important that the number of electrons given up during oxidation is the same as the number of electrons gained during reduction.

Coarse and fine adjustment The coarse adjustment knob should only be used with the lowest power objective lens. Once it is in focus, you will only need to use the fine focus. Using the coarse focus with higher lenses may result in crashing the lens into the slide.
