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.
