If 50.0g of kcl reacts with 50.0 g of 02 to produce KCLO3 according to the following equation, how many grams of kclo3 will be formed

Mass = 82.11 g

Explanation:

Given data:

Mass of KCl = 50.0 g

Mass of O₂ = 50.0 g

Mass of KClO₃ produced = ?

Solution:

Chemical equation:

2KCl + 3O₂   →     2KClO₃

Number of moles of KCl:

Number of moles = mass /molar mass

Number of moles = 50.0 g/ 74.5 g/mol

Number of moles = 0.67 mol

Number of moles of O₂:

Number of moles = mass /molar mass

Number of moles = 50.0 g/ 32 g/mol

Number of moles = 1.56 mol

Now we will compare the moles of oxygen and KCl.

          O₂          :          KClO₃

            3           :             2

           1.56       :          2/3×1.56 = 1.04 mol

        KCl          :          KClO₃

            2           :             2

           0.67       :         0.67

Number of moles of KClO₃ formed by KCl are less thus, it will act as limiting reactant.

Mass of KClO₃:

Mass = number of moles × molar mass

Mass = 0.67 mol ×122.55 g/mol

Mass = 82.11 g

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.

one negative thing it that it can kill water animals. another negative thing is it can cause the destruction of ecosystem. one way water pollution can be reduced is to conserve energy.
