What volume of hydrogen will produced at 1.45 atm and a tempeture of 20C by the reaction of 37.6g of magnesium 1Mg+2H2O--> Mg(OH)2+H2

V = 25.7 L.  

Explanation:

Hello there!

In this case, according to the given information, it turns out possible for us to solve for the volume of hydrogen, by firstly calculating the moles of this gas produced by 37.6 g of magnesium, according to the 1:1 mole ratio between them:

Now, we use the ideal gas equation:

To solve for the volume, and obtain:

Regards!

the dissolution of polymer can be thermodynamically described in 2 steps.

un recipient conține 6,4 moli de gaz. gazul hidrogen reprezintă 25% din totalul kilometrilor din container. în cazul în care presiunea totală este de 1.24 atm ceea ce este
