Answer:

Mass of Cl₂ produced 12.78 g

Explanation:

Given data:

Mass of MnO₂ = 16 g

Mass of HCl = 30.0 g

Mass of Cl₂ produced = ?

Solution:

Chemical equation:

MnO₂ + 4HCl        →        MnCl₂ + Cl₂ + 2H₂O

Number of moles of MnO₂:

Number of moles = mass / molar mass

Number of moles =  16 g/ 87 g/mol

Number of moles = 0.18 mol

Number of moles of HCl:

Number of moles = mass / molar mass

Number of moles =  30 g/ 36.46 g/mol

Number of moles = 0.82 mol

Now we will compare the moles of Cl₂  with MnO₂ and HCl.

                    MnO₂               :                Cl₂

                        1                   :                   1

                       0.18               :                0.18

                    HCl                  :                   Cl₂  

                       4                    :                     1

                      0.82               :                 1/4×0.82 = 0.205 mol

The number of moles of Cl₂ formed by HCl are less it will limiting reactant.

Mass of Cl₂ formed:

Mass = number of moles × molar mass

Mass = 0.18 mol × 71 g/mol

Mass = 12.78 g

A fish is removed from a contaminated lake. You determine that a particular toxin (X) is present in its cells at concentration X
netineya [11]
The level of toxins in the fish's cell is equivalent to the level of toxins in the water. Therefore, in order to reduce the toxins further, we should replace the now contaminated water with clean water. After the level of toxins in the fish's cell stops reducing, we replace the water with clean water once again.

Why do so many tornadoes occur in tornado alley
Shtirlitz [24]
<span>

The conditions in tornado alley are more favorable. In the summer, the plains of middle US get increasingly hot which in turn, cause updrafts as well as thunderstorms. When hot air becomes unstable and rises it meets cooler air above the thunderclouds, which causes tornadoes.</span>
