Magnesium stick
Indeks: HHPRĘT MAGNEZ
MAGNESIUM ROD 95.14% Mg
The rod is used to produce molecular hydrogen in water.
As a result of the chemical reaction of magnesium in contact with water, hydrogen and magnesium oxide are formed.
1. Put a magnesium rod into a vessel with a capacity of 1-2.5 liters and pour water.
2. We wait at least 30 minutes.
3. We have ready drinking water.
The rod will last for 1-2 years of daily use.
Single rod is packed in a string bag.
Dimensions: 16 mm x 90 mm
Weight: 32 g
Amount of hydrogen produced: 29.9 liters
(from the chemical reaction Mg + H₂O → MgO + H₂)
_____________________________________________
Magnesium reacts with water, and as a result of the chemical reaction, hydrogen is released and magnesium oxide is formed. Calculate how many grams of hydrogen were produced if 120 g of magnesium were used in the chemical reaction.
We write down the reaction equation:
Mg + H₂O → MgO + H₂ ↑
We write under the substances needed in our calculations their masses:
Mg + H₂O → MgO + H₂ ↑
24g 2g
We calculate our "x" (how many grams of hydrogen were created):
x = 10 g
Answer: The reaction produced 10 g of hydrogen.
