In a crystal, the molecules are closer together as they are in any solid. they have less room to move, and might even be combined together rather than individual
A. Adding a catalyst. A catalyst by definition is a compound that speeds up reaction rates.
Mendeleev was the first to arrange elements in a table based on their properties.
Answer: 0.336L
Explanation:
4HF + O2 —> 2F2 + 2H2O
1mole of HF occupies 22.4L at stp.
Therefore Xmol will occupy 0.67L i.e
Xmol of HF = 0.67/22.4 = 0.03mol
From the equation,
4moles of HF 2moles of F2.
Therefore, 0.03mol of HF will produce = (0.03x2)/4 = 0.015mol of F2.
1mol of F2 occupies 22.4L at stp.
Therefore, 0.015mol will occupy = 0.015 x 22.4L = 0.336L
