Explanation:
inhalation is the exchange of gas from the environmental oxygen to the oxygen in the tissues.
while Exhalation is the gas exchange of CO2 with O2 (the CO2 is exhales from high concentration to the environment of low concentration.
Answer:
NaCL
Explanation:
sodium chlorine is a typical ionic compound
Answer:
The reaction can produce 287 grams of iron(II) carbonate
Explanation:
To solve this question we must find the moles of iron(II) chloride that react. Using the chemical equation we can find the moles of iron(II) carbonate and its mass -Molar mass FeCO3: 115.854g/mol-
<em>Moles FeCl2:</em>
1.24L * (2.00mol / L) = 2.48 moles FeCl2
As 1 mol FeCl2 produce 1 mol FeCO3, the moles of FeCO3 = 2.48 moles
<em>Mass FeCO3:</em>
2.48mol * (115.854g / mol) =
<h3>The reaction can produce 287 grams of iron(II) carbonate</h3>
