Zn + 2 HCl ZnCl2 + H2

Chemistry
1 answer:
son4ous [18]4 years ago
4 0

Answer:

0.153 moles of hydrogen.

B) Multiply 10 grams of Zn x (1 mol Zn/65.39 g)

Explanation:

Given data:

Mass of zinc = 10 g

Moles of hydrogen = ?

Solution:

Chemical equation:

Zn + 2HCl  →  ZnCl₂ +  H₂

Number of moles of zinc:

Number of moles of zinc = mass/ molar mass

Number of moles of zinc = 10 g/ 65.4 g/mol

Number of moles of zinc = 0.153 mol

Now we will multiply the moles of Zn with hydrogen:

                     Zn            :            H₂

                      1              :              1

                     0.153       :            0.153

In general, how do the intermolecular attractions between particles in a gas compare with those between particles in a liquid?
Free_Kalibri [48]
In general the inter- molecular attraction between particles of gases is much more smaller than those found in the particles of liquids. Because of this, the particles of gases are usually far apart from one another while the particles of liquid are closer together compares to that of gases.

Bumek [7]

Answer:

J.J. Thomson’s experiments with cathode ray tubes showed that all atoms contain tiny negatively charged subatomic particles or electrons. Thomson proposed the plum pudding model of the atom, which had negatively-charged electrons embedded within a positively-charged “soup.”
