Answer:
=1.4953 moles
Explanation:
Iron (III) Oxide is reduced by carbon (II) oxide into Iron. According to the following equation, One mole of Fe₂O₃ react with 3 moles of CO to produce 2 moles of Fe. Thus the reaction ratio of CO to Fe₂O₃ is 3:1
Fe₂O₃₍s₎ + 3CO → 2Fe₍s₎ + 3CO₂₍g₎
125.6 grams of CO is equivalent to: 125.6g/28.0g/mol
=4.486 moles.
The number of moles of Fe produced by the reaction is:
=(4.486 moles×1)/3
=1.4953 moles
Answer:
Molarity of dextrose = 0.03 mol / L
Explanation:
Given data
mass of dextrose = 5 g
Concentration (Molarity) = ?
Solution
as mass is given so we find out number of moles
<em>Moles = mass / molar mass</em>
Molar mass of dextrose = 180.156 g/mol
Moles = 5 g / 180.156 g/mol
Moles = 0.03 moles
Now we find out molarity
<em>Molarity = moles of solute / Litres of solution</em>
As volume is not given so we suppose it as 1 L
Molarity of dextrose = 0.03 mol / 1 L
Molarity of dextrose = 0.03 mol / L
The correct answer would be we have no other frame of reference besides the sky. We could actually tell we are moving because of the shifting of stars in the sky over time. But really, “A” would be your answer. We have the same momentum of the earth. It’s like being on a train at a constant speed. The only way you know you’re moving is if you look out the window or the speed changes causing you to be pushed around. Same thing with earth, our only reference is the sky
Explanation:
Answer is that : no heat will flow
Answer:
The answer to your question is 2 liters
Explanation:
Data
Volume 1 = 1 l Volume 2 = ?
Temperature 1 = 25°C Temperature 2 = 25°C
Pressure 1 = 202.6 kPa Pressure 2 = 101.3 kPa
Process
As Temperature 1 is equal to temperature 2 we can use Boyle's law to solve this problem.
Pressure 1 x Volume 1 = Pressure 2 x Volume 2
-Solve for Volume 2
Volume 2 = Pressure 1 x Volume 1 / Pressure 2
-Substitution
Volume 2 = (202.6 kPa x 1) / 101.3
-Simplification
Volume 2 = 202.6 / 101.3
-Result
Volume 2 = 2 l
