Answer:

The second sample will produce 1563 grams of fluorine (F2)

Explanation:

The reaction will be MgF2 → Mg + F2

The stoichiometry ratio of MgF2 and F2 is 1 : 1.

That means for 1 mole of MgF2 consumed there is 1 mole of F2 produced.

The first sample produces 2.15 kg of magnesium and 3.36 kg of fluorine

The second sample produced 1 kg of magnesium and x kg of fluorine

This we can show in the following equation =

2.15kg / 3.36 kg = 1kg / x

2.15/3.36 = 0.63988

0.63988 = 1/ x

x= 1/0.63988  = 1.563 kg

1.563kg = 1563 grams

The second sample will produce 1563 grams of fluorine (F2)

In the reaction of iron water shown below what coefficient must be placed before the iron to balance the reaction fe+4h2o fe3o4
tiny-mole [99]
Answer is: three.
Unbalanced chemical reaction: Fe+4H₂O → Fe₃O₄ + 4H₂.
Balanced chemical reaction: 3Fe+4H₂O → Fe₃O₄ + 4H₂.
In balanced reaction, there is three iron atoms on the left and on the right, eight hydrogen atoms and four oxygen atoms on both side of chemical reaction.

two kilogram of nasialo4 zeolites are used in a water filter to remove calcium. after complete ion exchange the zeolite is remov
defon

After ion exchange with zeolite in water filter to remove calcium by substitute natrium ion with calcium ion, the weight of zeolite become 1.9578 kg.

ion exchange calculation can be done by using basic stoichiometry if we know how the reaction of the ion exchange. In this case where zeolite with natrium ion will be exchanged with calcium. The reaction of exchange will be like this:

2NaSiAlO_{4} + Ca^{2+} ⇒ Ca(SiAlO_{4}) _{2} + 2Na^{+}

Calculate the molecule weight of both zeolite
Atomic weight data:
Na = 23 gram/mole

Si = 28 gram/mole

Al = 27 gram/mole

O = 16 gram/mole

Ca = 40 gram/mole

Molecule weight

NaSiAlO_{4} = 142 gram/mole

Ca(SiAlO_{4}) _{2} = 278 gram/mole

Calculate mole from 2kg of zeolite with natrium :

2000 gram/ 142 = 14.0845 mole

Based on the stoichiometry, we got the mole of zeolite with calcium:

14.0845 mole x 1/2 = 7.0423 mole

Weight of zeolite after the ion exchanged with calcium:

7.0423 mole x 278 = 1957.8 gram = 1.9578 kg
