35.5 g of tetrachloroethane is added if 15 grams of chlorine is used with excess C_2H_2.

<h3>What is a balanced chemical equation?</h3>

A balanced equation is an equation for a chemical reaction in which the number of atoms for each element in the reaction and the total charge is  the same for both the reactants and the products.

Balanced chemical equation:

2Cl_2 (g) + C_2H_2 (g) → C_2H_2Cl_4(l)

In your case, 2 moles of chlorine gas are needed to produce 1 mole of tetrachloroethane, which implies that there's a 2:1 mole ratio between the two.

Calculating the mass of tetrachloroethane.

mC_2H_2Cl_4(l) = 15 g Cl_2 (g) X \frac{2 mol \;of \;Cl_2}{70 g \;Cl_2} X \frac{1 mol \;of \;C_2H_2Cl_4(l)}{2 mol \;Cl_2} X \frac{167.8 g \;C_2H_2Cl_4(l))}{1 mol \;C_2H_2Cl_4}

C_2H_2Cl_4(l) = 17.75 g

C_2H_2Cl_4(l) = 35.5 g

Hence, 35.5 g of tetrachloroethane is added if 15 gram of chlorine is used with excess C_2H_2

Write the half-reactions as they occur at each electrode and the net cell reaction for this electrochemical cell containing indi
AlexFokin [52]

Explanation:

The given cell reaction is as follows.

       In(s)| In^{3+}(aq) || Cd^{2+}(aq) | Cd(s)

Hence, reactions taking place at the cathode and anode are as follows.

At anode ; Oxidation-half reaction : In(s) \rightarrow In^{3+}(aq) + 3e^{-} ...... (1)

At cathode; Reduction-half reaction : Cd^{2+}(aq) + 2e^{-} \rightarrow Cd(s) ....... (2)

Hence, balance the half reactions by multiplying equation (1) by 2 and equation (2) by 3.

Therefore, net cell reaction is as follows.

      2In(s) \rightarrow 2In^{3+}(aq) + 6e^{-}

      3Cd^{2+}(aq) + 6e^{-} \rightarrow 3Cd(s)

Net reaction: 2In(s) + 3Cd^{2+}(aq) \rightarrow 2In^{3+}(aq) + 3Cd(s)

Thus, we can conclude that the overall cell reaction is as follows.

        2In(s) + 3Cd^{2+}(aq) \rightarrow 2In^{3+}(aq) + 3Cd(s)

A solution of ammonia has a pH of 11.8. What is the concentration of OH– ions in the solution?
balu736 [363]
PH + pOH = 14

11.8 + pOH = 14

pOH = 14 - 11.8

pOH = 2.2

[OH-] = 10 ^- pOH

[OH-] = 10 ^- 2.2

[OH-] = <span>6.33 x 10^-3 M
