Coefficient of balanced equation: __Fe + ___020) — _Fe_036)
lesya [120]

Answer:

- Four for iron, three for oxygen and 2 for iron (III) oxide:

4Fe+3O_2\rightarrow 2Fe_2O_3

Explanation:

Hello,

In this case, the oxidation of iron is a widely acknowledged reaction occurring in ships and other machines exposed to the air or highly oxidizing medias. Thus, by the effect of oxygen, iron undergoes oxidation typically to iron (III) oxide:

Fe+O_2\rightarrow Fe_2O_3

Nonetheless, the law of conservation of mass must be respected, therefore the coefficients balancing the reaction are four for iron, three for oxygen and 2 for iron (III) oxide:

4Fe+3O_2\rightarrow 2Fe_2O_3

Best regards.

(a) Calculate the total volume (in liters) of air an adult breathes in a day. (b) In a city with heavy traffic, the air contains
Furkat [3]

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:

  • P = 12 breath/min

in each breath it take an average  of 500 mL on air.

  • 1 breath ≅ 500 mL 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

What is the relationship between the source region of an air mass and the properties of the air mass?
Levart [38]
A source region must have certain temperature and humidity properties that can remain fixed for a substantial length of time to affect air masses above it. above it. Air mass source regions occur only in the high or low latitudes; middle latitudes are too variable.
